Abstract :
Based on the idea of contention reservation and polling, a user-dependent perfect-scheduling multiple access (UPMA) protocol for supporting node mobility and multihop architecture is described. In the protocol, only the nodes have packets to send contend to use the channel and the nodes without traffic transmission are immediately deleted from the polling list, thus it improves channel utilization greatly. Moreover, a collision avoidance and resolution protocol is proposed to guarantee a node to access the channel rapidly. Finally, taking a wireless network with star topology as an example, the network performance of Internet data traffic is simulated and related conclusions are given.
