可以理解的是，多个电子设备中每个电子设备可以保存各个电子设备是否在线，例如，如表3所示，每个电子设备可以保存的各个电子设备是否在线可以是一致的。换句话说，如果一个电子设备在线，并且有的电子设备可以检测到该电子设备在线，由于电子设备交互信息，则多个电子设备都可以确定该电子设备在线。
需要说明的是，一个电子设备在线可以理解为一个电子设备可以被搜索到，或者可以理解为电子设备在可通信的区域内或者可以被发现等，一个电子设备在线不是说该电子设备一定有已经建立好的网络连接。如果一个电子设备有已经建立好的网络连接可以认为该电子设备在线，或者即使该电子设备没有已经建立好的网络连接，只要能够被其他电子设备搜索到或者检测到，则可以认为该电子设备在线。换句话说，在线指的是电子设备可以被发现，不代表已经有数据通道了。

方法300中的多个电子设备可以是不同类型和/或不同场景中的电子设备的组合，例如多个电子设备可以是手机、车机、智能音箱、智能耳机以及其它不同类型的设备，或者这些不同类型的电子设备处于不同的场景，例如多个电子设备可以包括工作地的手机和居住地的平板。这样，方法300得到的网络拓扑关系可以适用于不同类型的电子设备进行传输数据，也可以适用于不同场景中不同类型的电子设备传输数据，能够提高适用性，也可以 将多个电子设备进行系统的规划。此外，方法300中的网络拓扑关系在物理上的形状可以是网状拓扑、星型拓扑、环形拓扑以及其他形状的拓扑结构。
为了更好的理解方法300的网络拓扑关系，下面结合图5描述方法300中的网络拓扑关系。如图5所示，用户在应用层能够实现两个设备之间的通信，实际上是链路层存在不同网络连接组成的物理子网络，不同的电子设备之间的通信可以通过链路层电子设备之间的实际的网络连接进行通信，在网络层电子设备之间可以通过不同的路径进行通信。网络拓扑关系在链路层表征为各个电子设备之间支持的网络连接方式，在网络层表征为各个电子设备之间存在的传输数据的路径。在应用层，不同电子设备之间进行传输数据时，用户不感知网络层和链路层的网络关系，只能感知到在应用层两个电子设备之间完成了数据交互。例如，如图5中，在应用层，手表与音箱在逻辑上是可以直达的，能够直接实现数据的交互，手表与音箱能够在应用层直接通信是因为在网络层和链路层进行了混合连接组网，手表与手机之间可以在链路层通过蓝牙网络传输数据，手机与音箱之间在链路层可以通过WiFi网络传输数据，这样，手表与音箱之间的传输数据的网络连接在网络层存在手表到手机的网络连接以及手机到音箱的网络连接。在图5中的网络层的实线表示传输数据的过程中的实际的网络连接，虚线表示支持的网络连接但未传输数据，同样链路层的实线表示传输数据过程中两个电子设备实际采用的蓝牙网络和WiFi网络，虚线表示两个电子设备支持的蓝牙网络和WiFi网络，但是未采用蓝牙网络和WiFi网络传输数据。
示例性的，在网络层的各个电子设备的之间的网络拓扑关系如图6所示，设备A、设备B、设备C和路由器通过网络连接，设备A、设备B、设备C和设备G之间两两之间通过网络连接。设备B与设备D、设备E、设备F分别通过网络连接。其中，设备G可以为远端设备。
与图6对应的链路层的各个电子设备之间的网络拓扑关系如图7所示。图7中，设备A、设备B、设备C和路由器通过wifi连接；设备A、设备B、设备C之间通过ble、wifi、wifip2p都有端到端连接；设备B和设备D、设备E之间保持ble端到端连接；设备B和设备F之间保持USB端到端连接；设备A、设备B、设备C和设备G之间都有lan或者p2p的端到端连接。图6和图7中实线表示网络连接已经建立好，虚线表示两个设备之间可以存在这些网络连接，但是还没有建立好。
下面具体结合图8描述电子设备之间如何利用方法300中已经建立好的网络拓扑关系传输数据。图8中仅仅描述两个电子设备之间传输数据，其他电子设备之间传输数据的方式与图8所示的传输方式一致，本申请实施例不详细描述。如图8所示，方法800包括：
S810，多个电子设备中的第一电子设备利用网络拓扑关系确定向多个电子设备中的第二电子设备传输第一数据的路径信息以及所述路径信息指示的传输路径上的相邻两个电子设备之间的网络连接方式。
其中，路径信息用于指示第一电子设备向第二电子设备传输的第一数据所经过的电子设备。
可选地，第一电子设备可以是业务发起方。或者网络拓扑关系中的中心节点可以确定路径信息以及路径信息指示的传输路径上的相邻两个电子设备之间的网络连接方 式，并将这些信息发送给第一电子设备。
具体地，S810，包括：第一电子设备根据网络拓扑关系选择能到达第二电子设备的传输路径以及这些传输路径上的电子设备之间的网络连接方式，例如，第一电子设备首先通过与第五电子设备之间的WiFi连接将第一数据发送到第五电子设备，第五电子设备再通过第五电子设备与第二电子设备之间的蓝牙传输方式将第一数据发送到第二电子设备，在这个例子中，第一电子设备可以根据网络拓扑关系确定的传输路径是第一电子设备-第五电子设备-第二电子设备，传输路径上第一电子设备与第五电子设备之间的连接方式是WiFi连接，第五电子设备与第二电子设备之间的连接方式是蓝牙连接。
可选地，S810还包括：第一电子设备根据网络拓扑关系以及S302交换得到的其他电子设备的信息选择能到达第二电子设备的传输路径以及这些传输路径上的电子设备之间的网络连接方式，例如根据网络拓扑关系以及电子设备的处理能力信息、电子设备的网络质量、电子设备的电量信息、电子设备的运动信息、电子设备的权重信息和电子设备的角色信息中的至少一种信息确定第一数据所经过的电子设备。
可选地，S810还包括，第一电子设备根据网络拓扑关系以及各个电子设备是否通信可达确定能够到达第二电子设备的传输路径以及这些传输路径上的电子设备之间的网络连接方式。
此外，若第一电子设备确定传输路径上的两个电子设备之间有多种网络连接方式，第一电子设备通过以下至少一种方式确定采用哪种网络连接方式。
方式一，第一电子设备可以根据自身当前已经建立的网络连接确定传输路径上与第一电子设备相邻的电子设备采用哪种网络连接方式，传输路径上第一电子设备与第五电子设备相邻，若第一电子设备与第五电子设备的某一网络连接正在连接没有断开，则可以复用正在连接的这种网络连接方式。例如，网络拓扑关系中第一电子设备与第五电子设备可以通过WiFi传输或者蓝牙传输，其中第一电子设备和第五电子设备已经建立了蓝牙连接，则可以确定蓝牙为这第一电子设备和第五电子设备之间的网络连接方式。若第一电子设备与第五电子设备之间不存在已经建立的网络连接，则第一电子设备根据第一数据的特征确定第一电子设备与第五电子设备之间网络连接。
此外，第一电子设备可以结合第一数据的特征确定传输路径上的其他相邻电子设备之间的网络连接。例如，若第一电子设备确定传输路径上的两个电子设备可以通过WiFi传输或者蓝牙传输，由于WiFi传输的时延低于蓝牙传输的时延，第一数据为时延要求高的数据，则第一电子设备可以确定WiFi为这两个电子设备之间的网络连接方式。若第一数据为时延要求低的数据，由于蓝牙比较节省功耗，则第一电子设备可以确定蓝牙为这两个电子设备之间的网络连接方式。
方式二，第一电子设备可以根据自身当前已经建立的网络连接以及第一数据的特征确定传输路径上与第一电子设备相邻的电子设备采用哪种网络连接方式。例如网络拓扑关系中第一电子设备与第五电子设备可以通过WiFi传输或者蓝牙传输，第一数据为时延要求高的数据，且这两个电子设备之间的WiFi处于连接状态，则第一电子设备可以确定WiFi为与第五电子设备之间的网络连接方式。又例如，网络拓扑关系中第一电子设备与第五电子设备可以通过WiFi传输或者蓝牙传输，第一数据为时延要求低的 数据，且这两个电子设备的蓝牙处于连接状态，则第一电子设备可以确定蓝牙为与第五电子设备之间的网络连接方式。再例如，网络拓扑关系中第一电子设备与第五电子设备可以通过WiFi传输或者蓝牙传输，第一数据为时延要求高的数据，且这两个电子设备的蓝牙处于连接状态，WiFi处于断开状态，由于处于连接状态的蓝牙满足不了第一数据的时延要求，则第一电子设备可以确定WiFi为与第五电子设备之间的网络连接方式。再例如，网络拓扑关系中第一电子设备与第五电子设备可以通过WiFi传输或者蓝牙传输，第一数据为时延要求低的数据，且这两个电子设备的WiFi处于连接状态，蓝牙处于断开状态，由于处于连接状态的WiFi满足可以满足第一数据的时延要求，则第一电子设备可以确定WiFi为与第五电子设备之间的网络连接方式，或者第一电子设备或第五电子设备对功耗要求比较高，则第一电子设备可以确定蓝牙为与第五电子设备之间的网络连接方式。
方式三，第一电子设备可以结合第一数据的特征在多种网络连接方式选择一种网络连接方式等。例如若传输路径上的两个电子设备可以通过WiFi传输或者蓝牙传输，由于WiFi传输的时延低于蓝牙传输的时延，第一数据为时延要求高的数据，则第一电子设备可以确定WiFi为这两个电子设备之间的网络连接方式。若第一数据为时延要求低的数据，则第一电子设备可以确定蓝牙为这两个电子设备之间的网络连接方式。
方式四，第一电子设备可以在两个电子设备的多种网络连接方式中任意选择一种网络连接方式。
在上述几种方式中，第一数据可能是高时延要求的数据或者低时延要求的数据，第一数据的特征为时延特征。可选地，第一数据的数据量可能大也可能小，第一数据的特征可以为数据量。可选地，第一数据可能是传输速率要求高的数据也可能是传输速率要求低的数据，第一数据的特征可以为传输速率要求。
可以理解的是，第一电子设备还可以通过其他的方式在两个电子设备的多种网络连接方式中确定一种网络连接方式，本申请实施例不予限制。
结合表2举例来说，若网络拓扑关系如表2所示，手机需要给眼镜传输数据，手机与眼镜之间没有网络连接，但是眼镜与PAD之间有WiFi连接，PAD与手机之间没有网络连接，但是PAD与PC之间有BR或者WiFi连接，PC与手机之间有BR或者WiFi连接。因此，手机可以确定向眼镜传输数据的路径为：手机-PC-PAD-眼镜。手机可以结合上述四种方式的至少一种方式确定这条传输路径：手机-PC-PAD-眼镜这条路径上任意两个电子设备之间的网络连接方式。
举例来说，若网络拓扑关系如表2所示，手机需要给眼镜传输数据，手机与眼镜之间没有网络连接，但是眼镜与PAD之间有WiFi连接，PAD与手机之间没有网络连接，但是PAD与PC之间有BR或者WiFi连接，PC与手机之间有BR或者WiFi连接。因此，手机需要确定这些设备是否在线，若在线信息为表3所示，手机可以确定PC、PAD和眼镜都在线，手机可以确定向眼镜传输数据的路径为：手机-PC-PAD-眼镜。手机可以结合上述四种方式的至少一种方式确定这条传输路径：手机-PC-PAD-眼镜任意两个电子设备之间的网络连接方式。
此外，若第一电子设备确定有多条传输第一数据的传输路径。可选地，若电子设备之间还交换了电量信息、网络质量和电子设备的处理能力信息，则第一电子设备可 以结合电子设备的电量、第一数据的业务类型、第一数据的时延要求、电子设备的处理能力信息和网络质量中的至少一项以及网络拓扑关系在多条传输路径中选择一条传输路径。具体地，第一电子设备首先根据网络拓扑关系选择能到达第二电子设备的多条传输路径，并且也能确定这些传输路径上电子设备之间的网络连接方式。第一电子设备需要结合多条路径上的电子设备的电量、第一数据的业务类型、第一数据的时延要求和网络带宽至少一项在多条路径中选择一条传输路径，利用传输路径传输数据。
可选地，若S302交换的信息包括各个电子设备的服务信息，第一电子设备可以根据第二电子设备的支持的服务确定向第二电子设备发送第二电子设备支持的服务对应的第一数据。例如第一电子设备需要将第一数据投屏到第二电子设备，第一电子设备需要确定第二电子设备是支持投屏服务的，才可以传输投屏服务对应的第一数据。
S820，第一电子设备根据路径信息以及所述路径信息指示的传输路径上的相邻两个电子设备之间的网络连接方式向第二电子设备传输第一数据。
例如，S820，包括，第一电子设备与路径信息指示的第五电子设备建立相应的网络连接，并采用建立的网络连接方式传输第一数据，第五电子设备与第二电子设备建立网络连接方式，并采用建立的网络连接传输第一数据。当路径信息指示的两电子设备间的网络连接已经处于连接状态，则无需重新建立，示例性的，第一电子设备确定传输路径上的第五电子设备和第二电子设备之间通过WiFi传输，当第五电子设备和第二电子设备之间的WiFi处于连接状态，则第五电子设备和第二电子设备，可继续使用处于已连接状态的WiFi通道传输数据；当第五电子设备和第二电子设备之间的WiFi未处于连接状态，则第五电子设备和第二电子设备可建立WiFi连接，以传输数据。这样，第一数据可以到达第二电子设备。当然路径信息指示的传输路径上可以包括除了第五电子设备之外的其他的电子设备或者也可以不包括第五电子设备。
需要说明的是，第一电子设备与第二电子设备之间也可以直接传输第一数据，换句话说第一电子设备确定的路径信息上可以只有第一电子设备和第二电子设备，没有其他的电子设备。
需要说明的是，若路径信息指示的传输路径上的相邻两个电子设备之间本身存在网络连接，则不需要再重新建立网络连接，只需要利用存在的网络连接传输第一数据即可。若路径信息指示的传输路径上的相邻两个电子设备之间不存在网络连接则建立相应的网络连接，利用建立的网络连接传输第一数据。下面描述建立网络连接的方式：
方式一：在S820之前，方法800还包括：第一电子设备确定传输路径以及传输路径上的相邻两个电子设备之间的网络连接方式之后，第一电子设备可以将网络连接指示信息(用于指示传输路径上相邻两个电子设备之间的网络连接)直接或者间接发送给传输路径上的各个电子设备，相邻两个电子设备之间根据网络连接指示信息建立相应的网络连接。举例来说，传输路径为第一电子设备-第五电子设备-第二电子设备，第一电子设备确定第一电子设备与第五电子设备之间的网络连接为ble，第五电子设备与第二电子设备之间的网络连接为WiFi-p2p。第一电子设备与第五电子设备建立ble连接，第一电子设备通过建立的ble连接向第五电子设备发送网络连接指示信息，网络连接指示信息用于指示第五电子设备与第二电子设备之间的网络连接为WiFi-p2p连接。第五电子设备与第二电子设备建立WiFi-p2p连接。换句话说，方法800在传输数据之前可以 将传输路径上的网络连接建立好，或者是有的网络连接本身是连接状态，则无需建立网络间接直接传输数据即可。
在方式一下，携带第一数据的报文的报文头可以携带路径信息以及路径信息指示的传输路径上的当前相邻两个电子设备之间的网络连接方式，这样，传输路径上的任何一个电子设备接收到第一数据之后可以根据这些路径信息确定下一跳节点。
此外，携带第一数据的报文的报文头中的源地址为第一电子设备的地址，目的地址为第二电子设备的地址，例如第一数据的源地址为第一电子设备的ID，目的地址为第二电子设备的ID，这样，在整个路由的过程中可以保证第一数据能够到达第二电子设备，且第二电子设备也能够根据源地址获知第一数据来源于第一电子设备。
为了更好的理解方式一，图9所示的实施例的前提是设备A与设备B之间没有建立WiFi-p2p连接，设备B与设备E之间也没有建立ble连接，若电子设备保存了如图7的网络拓扑关系，下面结合图9描述传输数据的过程。如图9所示，包括：
S901，设备A确定需要向设备E发起通信请求。
S902，设备A根据S810确定设备A到设备E的传输路径是先到设备B，再到设备E，设备A可以确定设备A与设备B之间利用WiFi-p2p传输。这样路由信息是设备A-设备B-设备E，设备A与设备B之间采用WiFi-p2p传输，设备B与设备E之间采用ble传输。
S903，设备A与设备B建立WiFi-p2p连接。
S904，设备A通过建立的WiFi-p2p连接发送网络连接指示信息，指示设备B与设备E之间为ble连接。
S905，设备B与设备E建立ble连接。
换句话说，设备B可以是传输数据之前获知与设备E之间为ble连接，并将ble提前建立好。
S906，设备A通过WiFi-p2p连接向设备B发送携带第一数据的报文。报文的格式如图10所示，业务标识用于唯一标识当前业务，报文类型表示当前报文的类型为文件类型，连接方式表示设备A与设备B之间是WiFi-p2p连接，源地址为设备A的ID，目的地址为设备E的ID，设备A的下一跳链表为设备B-设备E，因为设备A为首节点，设备A的上一跳节点链表为空，图10中数据部分可以为第一数据。
需要理解的是，S906在S903之后，但是S906与S904-S905的任一项顺序没有限制。
S907，设备B通过ble连接向设备E发送携带第一数据的报文，发送给设备E的报文格式如图11所示，其中与图10不同的是，图11中连接方式为ble，图11中的上一跳链表为设备A，下一条链表为设备E。
设备E接收到报文之后通过原路径以同样的方式返回应答报文，应答报文用于表示设备E收到第一数据。
此外，设备A与设备B传输完报文之后，可以断开WiFi-p2p连接，设备B与设备E传输完报文之后，可以断开ble连接。
方式二，S820中，携带第一数据的报文的报文头可以携带路径信息以及路径信息指示的传输路径上的任意相邻的两个电子设备之间的网络连接方式，这样，传输路径上的任何一个电子设备接收到第一数据之后可以根据这些路径信息以及路径信息指示的传输路径上的电子设备之间的网络连接方式确定下一跳节点以及与下一跳节点之间 的网络连接方式。
为了更好的理解方式二，若电子设备保存了如图7的网络拓扑关系，图12所示的实施例的前提是设备A与设备B之间没有建立WiFi-p2p连接，设备B与设备E之间也没有建立ble连接，下面结合图12描述传输数据的过程。如图12所示，包括：
S1201，设备A确定向设备E发起通信请求。
S1202，设备A根据S810确定设备A到设备E的传输路径是先到设备B，再到设备E，设备A可以确定设备A与设备B之间利用WiFi-p2p传输。这样路由信息是设备A-设备B-设备E，设备A与设备B之间采用WiFi-p2p传输，设备B与设备E之间采用ble传输。
S1203，设备A建立与设备B之间的WiFi-p2p连接。
S1204，设备A向设备B发送携带第一数据的报文，携带第一数据的报文的格式如图13所示，连接方式字段表示设备A与设备B之间是WiFi-p2p连接，设备B与设备E之间为ble连接，其他字段的定义与图10相同。
S1205，设备B根据图13中的连接方式确定与设备E之间的连接为ble连接，并与设备E建立ble连接。
换句话说，S1205中，设备B可以根据携带第一数据的报文中获知与设备E之间的连接为ble连接。
S1206，设备B向设备E发送携带第一数据的报文，携带第一数据的报文的格式如图14所示，14中的连接方式字段表示设备B与设备E之间为ble连接，其他字段的定义与图10相同。
当然，图14中的连接方式字段也可以为图13中的连接方式字段。
设备E接收到报文之后通过原路径以同样的方式返回应答报文。
此外，设备A与设备B传输完报文之后，可以断开WiFi-p2p连接，设备B与设备E传输完报文之后，可以断开ble连接。
作为S810和S820可替换的方式，第一数据的源地址为第一电子设备的地址，目的地址为第二电子设备的地址，例如第一数据的源地址为第一电子设备的ID，目的地址为第二电子设备的ID。网络拓扑关系中的任何一个电子设备都可以根据网络拓扑关系以及本地的策略确定第一数据的下一个节点，具体地，第一电子设备只需要根据网络拓扑关系以及本地的策略确定第一数据到达第二电子设备的下一个节点是什么，下一个节点接收到第一数据之后结合网络拓扑关系以及本地的策略确定第一数据到达第二电子设备的下一个节点是什么，依次可以将第一数据传输到第二电子设备。这样，第一数据的数据包无需携带路径信息以及路径信息指示的传输路径上的电子设备之间的网络连接方式，每个电子设备接收到第一数据时自身确定下一跳节点以及与下一跳节点之间的网络连接方式。
上述提到的本地策略可以是电子设备自身根据交换得到各个电子设备的信息制定本地策略，每个电子设备制定的本地策略可以相同也可以不相同，本申请实施例不予限制。
可选地，方法300中，可能不断地有电子设备之间能够互相发现，则会导致网络拓扑关系不停的变化，使得多个电子设备需要不断地交换信息，不断地更新网络拓扑关系，这样会导致开销比较大，功耗也比较大，因此方法300中的确定的网络拓扑关系根据是定时 更新或者是满足一定的触发条件再更新，下面结合图15的描述满足触发条件之后更新方法300中的网络拓扑关系。
S1501，开始。
S1502，多个电子设备之间持续自发现。
S1503，多个电子设备之间持续交换信息。
可选地，在S1503中多个电子设备之间持续交换信息可以是定期交换信息，或者是在有信息在原来基础上发生变化之后再交换信息。举例来说，若一个电子设备的检测到自身与另一个设备的网络连接从连接状态变为断开状态，则可以将变化的信息进行交换。
具体地，电子设备交换的信息参见S302的描述。
S1504，第一电子设备根据交换信息确定一个或多个电子设备的场景是否发生变化。若场景发生变化，则执行S1505，否则回到S1502。
可选地，第一电子设备保存有方法300得到的网络拓扑关系，若网络拓扑关系中的任一电子设备的S302中的任何一种信息发生变化，该电子设备将变化后的信息直接或者间接发送给第一电子设备，第一电子设备根据变化后的信息确定电子设备的场景是否发生变化。例如，变化后的信息包括：SSID，第一电子设备根据SSID确定某一电子设备的场景是否发生变化。举例来说，某一电子设备的SSID从家庭网络的SSID变成车载网络的SSID，该电子设备将变化后的SSID直接或者间接发送给第一电子设备，第一电子设备根据变化后的车载网络的SSID确定该电子设备的场景发生变化。
可选地，第一电子设备还可以根据网络能力信息、网络质量和运动信息中的至少一项以及SSID确定某一电子设备的场景是否发生变化。
在一些可能的实现方式中，第一电子设备可以是多个电子设备中任一电子设备。
在一些可能的实现方式中，第一电子设备可以是多个电子设备中的中心节点，此时，多个电子设备交换的信息包括角色信息。或者第一电子设备可以是多个电子设备中权重较高的节点，此时多个电子设备交换的信息包括权重信息。
S1505，第一电子设备根据交换信息确定多个电子设备中是否存在电子设备为加速运动。
具体地，S302中，电子设备交换的信息包括电子设备的运动信息，这样，第一电子设备可以根据运动信息确定多个电子设备的运动状态。当第一电子设备确定多个电子设备中的某个电子设备正在加速运动时，则回到S1502；当第一电子设备确定多个电子设备中的电子设备运动速度比较小时，则执行S1506。
在S1505中，第一电子设备可以根据某个电子设备的运动信息指示的运动速度以及该电子设备历史的运动速度确定速度的变化量，若速度的变化量大于速度阈值，则认为该电子设备为加速运动，否则不是加速运动。或者第一电子设备可确定某个电子设备运动信息指示的该电子设备的加速度，若加速度大于速度阈值，则认为该电子设备为加速运动，否则不是加速运动。
S1506，第一电子设备确定增加的电子设备的数量是否大于第一数量阈值或者减少的电子设备的数量是否大于第二数据阈值。
具体地，第一电子设备根据交换信息确定增加的电子设备的数量。第一电子设备根据下线的电子设备确定减少的电子设备的数量。若增加的电子设备的数量大于第一数量阈值 或者减少的电子设备的数量大于第二数据阈值，则执行S1507。若增加的电子设备的数量小于或等于第一数量阈值或者减少的电子设备的数量小于或等于第二数据阈值，则回到S1502。
具体地，随着网络中电子设备的增加或者减少，第一电子设备可以根据增加的电子设备的数量或者减少的电子设备的数量确定是否需要触发自组网。例如，方法300中，10个电子设备组成了网络拓扑关系，随着设备的持续互相发现以及交换信息，例如增加了3个电子设备执行S1502-S1503之后，第一电子设备会接收到增加的3个电子设备交换的信息，因此第一电子设备可以确定增加的电子设备的数量。又例如，第一电子设备定期接收不到电子设备的信息，即检测不到电子设备的信息，则第一电子设备可以确定该电子设备不在线，这样会使得表2中电子设备对应的某一行都为“X”，不在线的电子设备也可以称为减少的电子设备。
可选地，第一数量阈值和第二数据阈值可以是协议规定的，或者可以是一个电子设备确定的发送给其他的电子设备的。
S1507，第一电子设备触发连接自组网。
具体地，第一电子设备触发连接自组网可以是第一电子设备向网络拓扑关系中的其他电子设备发送组网指令，其他电子设备接收到组网指令之后，根据组网指令更新自身保存的网络拓扑关系示意图。具体地，第一电子设备向其他电子设备发送组网指令可以通过网络拓扑关系中的电子设备通过多跳传输依次发送到各个电子设备。例如，第一电子设备启动自组网，并可以向第四电子设备发送组网指令，第四电子设备接收到组网指令后启动自组网并将组网指令发送到第二电子设备，第二电子设备接收到组网指令之后，启动自组网。
可选地，若两个电子设备之间已经建立网络连接，则可以通过建立的网络连接发送组网指令，若两个电子设备没有建立网络连接，则两个电子设备之间可以建立网络连接，再利用建立的网络连接传输组网指令。
可以理解的是，组网指令的格式可以是协议规定的，多个电子设备可以按照协议规定的解析组网指令。
第一电子设备可以开启智能连接组网以触发连接自组网，例如，第一电子设备的某个控件可以开启执行连接组网或者第一电子设备的某个控件可以触发显示界面显示提醒用户是否需要开启自组网。
在第一电子设备触发连接自组网之后回到S1501。
上述方法图15描述的是，当电子设备的场景发生变化、变化的电子设备的数量满足阈值并且电子设备的运动不是加速运动时才触发自组网，这个变化的顺序不做任何限定，换句话说，S1504-S1506这三个步骤的顺序不做任何限制，可以先判断变化的电子设备的数量，再判断电子设备是否加速运动，最后判断场景是否发生变化。或者上述方法1500可以包括S1504-S1506中的任意一个条件可以触发自组网，或者可以包括S1504-S1506中的两个条件可以触发自组网，本申请实施例不予限制。
可以理解的是，方法1500中只是举例描述触发自组网需要满足的条件，还可以是其他的条件出发自组网，换句话说，本申请实施例对触发自组网的条件并没有任何限制。
需要说明的是，每个电子设备开启智能连接组网可以理解为每个电子设备更新自身的保存的网络拓扑关系。
也需要说明的是，方法800中传输数据可以是利用方法300得到的网络拓扑关系传输数据也可以是利用方法1500更新后得到的网络拓扑关系传输数据。
为了更好的说明本申请实施例提供的方法，下面结合具体的例子举例说明，如图16所示，以手机和手表为例。
S1601，手机在后台定期发送消息，消息中携带手机的设备ID。手表能够通过蓝牙或wifi接收到手机发送的消息。
当然S1601中的消息还可以携带账号和各类标志位。
S1602，手表接收到手机发送的消息后，回复响应消息给手机，响应消息中包括手表的设备ID。
或者S1602中，响应消息还可以包括手表的账号和各类标志位。
如果S1601中手机发送的消息携带手机的设备ID，则S1602中手表回复的响应消息中携带手表的设备ID；如果S1601中手机发送的消息携带手机的设备ID、账号和各类标志位，则S1602中手表回复的相应消息中可携带手表的设备ID、账号和各类标志位。
S1603，手机根据手表回复的响应消息中携带的手表的设备ID确定手表是新上线的设备，且之前手机未与手表建立过网络连接。
在一种可能的实现方式中，在S1601之前，用户对手机与手表之间进行了绑定，例如，通过pin码或者QR码等绑定，这样，在S1601之前手机确定手表为可信设备。
在另一种可能的实现方式中，当S1602中的响应信息包括手表的账号时，手机确定手表的账号与自身的账号是否相同，若相同，则手机可以确定手表为可信设备。
S1604，手机向手表发送建立连接请求，建立连接请求中携带手表的Mac地址。
由于手表是信任设备，因此手机可以获知手表的Mac地址。
S1605，手机与手表建立网络连接，如蓝牙连接，并互相认证。
S1606，手机通过建立的网络连接向手表发送自身的基本信息、网络能力信息和处理能力信息。手表存储手机的这些信息。
示例性的，手机向手表发送自身的基本信息可以为：
Figure PCTCN2021112168-appb-000010
Figure PCTCN2021112168-appb-000011
其中，手机向手表发送的处理能力信息用于指示手机的处理能力。手表根据手机发送的处理能力信息指示的处理能力与自身的处理能力进行比较，发现手机的处理能力强于自身的处理能力，则手表可以确定自身的角色(Role)为普通节点。
在一种可能的实现方式中，若手机也未接收到其他的设备发送的基本信息和网络能力信息，即此时的拓扑信息为空，手机还可以在S1606中向手表发送的拓扑信息为空或者可以不发送拓扑信息。
S1607，手表通过建立的蓝牙连接向手机发送自身的基本信息、网络能力信息和处理能力信息。手机存储手表的这些信息。
示例性的，手表向手机发送自身的基本信息可以为：
{NetworkId：4d3b-4535-6c37-f243//标识唯一组网设备
DeviceId：4d3b-4535-6c37-f243//设备标识
DeviceName：kk’s watch//设备名称为kk的手表
DeviceType：06D//设备类型为手表
Weight：40//当前设备的权重值，通过节点网络能力和类型计算
Role：中心节点//设备角色
SwVersion:v1.1//系统版本号
}
示例性的，手表向手机发送自身的网络能力信息可以为：
Figure PCTCN2021112168-appb-000012
在一种可能的实现方式中，S1607在S1606之后，即此时手表根据手机发送的处理能力信息已经确定自身为普通节点，则S1607中，手表发送的角色信息(Role)为普通节点。
在另一种可能的实现方式中，S1607与S1606同时进行了，即手表不知道手机的处理能力信息，在S1607中，手表发送的角色信息(Role)为中心节点。
手机在S1607接收到手表的处理能力信息之后，将手表的处理能力信息所指示的处理能力与自身的处理能力进行比较，手机确定自身的处理能力高与手表的处理能力，手机将自身确定为中心节点。
经过S1606和S1607就完成了手机与手表的基本信息、网络能力信息和处理信息的交换。
其中，手机与手表执行完S1606和S1607之后，可以断开用于交换信息的蓝牙连接，当然也可以不断开蓝牙连接。
S1608，手机可以根据交换的信息确定网络拓扑关系。
S1609，手表可以根据交换的信息确定网络拓扑关系。
作为S1609可替换的方式，手机执行完S1608之后，可以将确定的网络拓扑关系发送给手表，例如，如果手机与手表之间的蓝牙正在处于连接状态，则通过手机与手表之间的蓝牙发送网络拓扑关系。如果手机与手表之间不存在处于连接状态的网络连接，则可以建立任意一种手机和手表都支持的网络连接，手机利用建立的网络连接向手表发送网络拓扑关系。
例如结合S1606和S1607中的例子，手机和手表确定的网络拓扑关系为：
Figure PCTCN2021112168-appb-000013
Figure PCTCN2021112168-appb-000014
S1610，手机周期性发送消息，消息中携带手机的设备ID。
其中，S1610中手机周期性发送的消息包括的内容与S1601中消息携带的内容也可以相同，本申请实施例不予限制。
S1611a，手表接收到手机发送的消息之后，回复响应消息，响应消息中携带手表的设备ID。
经过S1610与S1611，手机可周期性或定期发送广播消息，手表与手机可确认互相在线。
其中，手机和手表在第一次交换信息后，手机可继续周期性发送广播消息，以确定手表是否在线。手表可只发送设备在线的响应消息，而无需再发送自己的基本信息和网络能力信息，而当自身的基本信息和/或网络能力信息发生变化时，才会向对端发送自己变化后的基本信息和/或网络能力信息。具体的，当手表的基本信息和/或网络能力信息发生变化时，手表可以与手机建立任意一种手机和手表都支持的网络连接，并发送变化后的基本信息和/或网络能力信息。
S1611b，若手表接收不到手机发送的消息，也不会回复响应消息，手机定期(如5min)接收不到手表发现的响应消息，则可以确定手表不在线。
在一种可能的实现方式中，当手机确定手表不在线时，可以将网络拓扑关系中关于手表的信息删除，并且将表3中的“O”改为“X”；或者手机多次发送消息都没有收到手表的响应消息，且次数大于预设值，手机删除网络拓扑关系中关于手表的信息。
在另一种可能的实现方式中，当手机确定手表不在线时，可以不删除网络拓扑关系中关于手表的信息，继续保存，当下次手表上线时，只需要交换变化的信息，不交换没变化的信息。
手机继续执行S1610。当手表能再次接收到手机发送的消息时，手表执行S1611a。
S1612，手表确定自身的基本信息、网络能力信息或者处理信息发生变化，在手表执行S1611a的情况下，手表可以执行S1612。
S1613，手表发送建立连接请求消息，建立连接请求消息中携带手机的Mac地址。
S1614，手表与手机建立网络连接，如蓝牙连接，并互相认证。
S1615，手表通过建立的蓝牙连接传输变化后的信息。
当然，根据具体实现设计，若手机确定手表不在线之后，手机删除了关于手表的信息，则S1615中，手表可以利用建立的网络连接传输自身的基本信息、网络能力信息和处理信息。
S1616，手机根据变化后的信息更新S1608中确定的网络拓扑关系。
当然，手表也根据自身变化后的信息更新S1609中确定的网络拓扑关系。
其中，S1616中，手机可以也接收到多个设备的变化的信息之后更新网络拓扑关系，不限于只接收到手表变化的信息就更新。
手机保存有手机与手表之间的网络拓扑关系，当新上线台灯之后，台灯向手机发送的信息与手表向手机发送的信息基本一致，手机根据台灯发送的信息更新网络拓扑关系，不同的是，手机可以将自身保存的手机与手表之间的网络拓扑关系发送给台灯，这样，台灯就可以根据自身的信息以及手机发送的网络拓扑关系确定新的网络拓扑关系。
经过S1601-S1616，手机和手表确定了网络拓扑关系，当手机需要向手表传输数据时，手机根据确定的网络拓扑关系，确定手机到手表通过蓝牙传输，当手机确定与手表之间的蓝牙正在连接时，手机通过正在连接的蓝牙向手表传输数据，当蓝牙未连接时，手机建立与手表之间的蓝牙连接，并通过建立的蓝牙连接传输数据。
需要说明的是，本申请实施例中，各个电子设备交换的信息可以包括一个或多个信息，根据需要进行设计具体交换哪些信息，且各个电子设备交换的信息可以通过一次交换或者通过多次交换，例如针对基本不变的信息可以一次交换，经常变化的信息可以变化后在交换，本申请不予任何限制。
也需要说明的是，本申请实施例中前述描述的是，多个电子设备中每个电子设备保存的网络拓扑关系一致，当然多个电子设备中每个电子设备保存的网络拓扑关系也可以不一致，这样，每个电子设备可以利用自身保存的网络拓扑关系确定数据传输的下一跳节点，无需首节点进行全局规划。
本申请实施例中的组网定义为：在蓝牙、WiFi等信号可检测到的范围内存在有信任关系的多个电子设备，一个设备会和其他设备维持一个逻辑上的连接，在系统运行时可同步这些电子设备的状态和信息。这些可信的电子设备就形成了一个组网。基于组网，业务可以实现无感发现连接，在业务请求时，无需等待发现连接认证过程即可直接发起业务。
因此，本申请实施例方法，可以在网络层将不同连接的网络进行组网，形成一个网络拓扑关系，这样，网络拓扑关系中的任何两个设备进行通信时，都可以基于该网络拓扑关系实现两个电子设备之间的通信。网络拓扑关系可以包括多个电子设备之间中任意两个电子设备之间的网络连接，这样，两个设备在传输数据时直接根据网络拓扑关系确定传输路径，避免两个电子设备之间需要先发现两个电子设备之间的一个或多个网络连接方式，再在一个或多个网络连接方式中选择一个合理的网络连接建立连接所带来的时延，有利于降 低传输数据的时延，并且可以系统的规划设备之间的连接关系。此外，网络拓扑关系可以根据网络中的电子设备的信息进行实时的更新，从而可以保证实时性。
