Abstract:
1. A method for managing channel access by nodes in a wireless communication network, the method comprising: monitoring, by at least one node in the network, at least one of data transmissions and intent-to-transmit messages by neighboring nodes; determining, by the at least one node, the identity of those time slots in use by the at least one node and by the neighboring nodes and those time slots not in use by the at least one node and the neighboring nodes; broadcasting, by the at least one node, information including the identity of used and unused time slots to the other nodes, such that the other nodes can chose an unused time slot for packet transmission; operating the at least one node to compute the transmit energy used to transmit data packets, based on the predicted path loss of monitored nodes directly connected to the at least one node; and broadcasting the computed transmit energy from the at least one node when the at least one node changes the level of transmit energy.
