AN IMPROVED MOBILE AD-HOC NETWORK

摘要

A mobile communication system which consists of a plurality of MANETs and nodes, which comprises a transceiver at each node. Each transceiver is a combination of a hopping transmitter operating according to a predetermined hopping sequence and rate and a wideband reference receiver, that can simultaneously receive at once, the whole operating band assigned to the system. Each transceiver further includes a circuitry for reallocating simultaneously receiving channels, dynamically spread over a wideband frequency range and circuitry for determining transmission hopping patterns to use the least possible number of frequencies according to the active population status of nodes that belong to the plurality of MANETs. This circuitry is also used for adapting the transmission scheme of the alien transceivers by finding 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, neighboring the counterpart receiver transmits, while determining proper transmission frequency for each transmitting node.
