The Performance Analysis of Packet Radio Network with Multihop Structure

A multihop packet radio network with RTS/CTS multiple access protocol of IEEE 802.11 MAC is presented,with emphasis on its throughput analysis and comparison of throughput among slot ALOHA,CSMA and RTS/CTS multiple access protocols.In packet radio network,robust clustering network structure can be achieved rapidly by minimal ID clustering algorithm with lower control information,and it is efficient to take advantage of multiple channels with suitable medium access control (MAC) protocol.But it is unable to avoid hidden terminal problem of carrier sense multiple access due to two hop clustering structure in each cluster.However,Request To Send (RTS) and Clear To Send (CTS) access method in IEEE 802.11 MAC protocol can reduce the collision time of packet greatly so as to improve the performance of packet radio network.
