Abstract

The present invention is directed to a method for reducing the guard time of a Mobile ad hoc networking (MANET) system during reception according to which a transceiver architecture that is provided at each node includes a combination of a hopping transmitter and a plurality of hopping narrowband independent receivers that are capable of receiving and processing the entire operational band assigned to the system at once and that include channel frequencies dynamically selected within a wide operating bandwidth. Alternatively the transceiver architecture includes a non hopping wideband receiver capable of receiving and processing the entire operational band assigned to the system at once. Several channels arbitrarily spread over a frequency band assigned to the system are simultaneously received while keeping the architecture of the MANET system. The transmission hopping patterns are determined to use the least possible number of frequencies. For each transmitting node time slots in which a counterpart receiver at each remaining active node is not transmitting and a frequency channel in which no other active node transmits are found. The transmission frequency is then determined and if no other node had chosen the same time slot and if the transceiver is not transmitting in the slot the transmission is received while allowing relay nodes to transmit simultaneously using different channels. Whenever a plurality of narrowband independent receivers is used for reception guard time is allocated to time slots on demand. Otherwise no guard time is allocated to the time slots.
