Collision Free MAC Protocol for Multi-Hop Wireless Networks
面向多跳无线网络的无冲突MAC 协议

Collision rate increases significantly with the appearance of hidden nodes in multi-hop wireless network, which results in unsuccessful transmissions and leads to performance degradation of the network. The RTS/CTS handshakes of 802.11DCF can not eliminate hidden nodes, and the situation becomes worse when the nodes are equipped with higher speed wireless devices, which require higher signal to interference and noise ratio (SINR) for successful reception. This paper analyzes the prevalence of hidden nodes i...
