A New MAC Algorithm for Ad HOC Network Based on Ultipacket Reception and RTS Refused Probability

摘要

Medium access control (MAC) is a key issue in multi-hop ad hoc network where a common channel is shared by a population of users. In recent years, the technique of multipacket reception (MPR) and multipacket separation (MPS) is widely applied in the area of wireless network. Based on the technique of MPR and MPS, the paper puts forward the RTS refused probability in the queue management of network layer and brings forward a new medium access control algorithm for ad hoc network. The performance analysis of the algorithm has been given. We also compare the performance of this algorithm with IEEE 802.11. The simulation result shows that the new algorithm can increase the throughput of the ad hoc network.
