Abstract:
1. A method for communicating between nodes in an ad-hoc multi-channel medium access control (MAC) communication network, wherein the ad-hoc multi-channel MAC communication network comprises a reservation channel for communicating handshake messages relating to each of a plurality of data packet transmissions, and a data channel for communicating the data packet transmissions upon successful handshake on the reservation channel, the method comprising: comparing a size of a data packet message to a predetermined maximum size; wherein the predetermined maximum size is a size of Request-To-Send (RTS) message; transmitting the data packet message from a source node to a destination node over the reservation channel as an initial message between the source and destination nodes when the size of the data packet message is less than the predetermined maximum size; and performing a request-to-send/clear-to-send handshake on the reservation channel between the source and destination nodes when the size of the data packet message is at least the predetermined maximum size, and transmitting the data packet message from the source node to the destination node over the data channel when the request-to-send/clear-to-send handshake is successful.
