A Network Coding Scheme in Wireless Mesh Networks
Shizhong Yang · Beijing Youdian Xueyuan xuebao · 2010
A wireless mesh transport control protocol(TCP) network coding scheme based on rate-matching receiver is proposed.A network coding(NC) layer to code transport control protocol data(TCP-DATA) and transport control protocol ack(TCP-ACK) on mesh connectivity layer(MCL) is constructed,and modified distribution coordination function request to send/clear to send(DCF RTS/CTS) mechanism to match data rate in the receiver is adopted.Actually a real 3 hops wireless mesh linear network has been constructed,capturing the TCP network coding data based on the proposed scheme,therefore,it is concluded that the TCP throughput of the end-to-end system is approximately 20% higher than non-NC scheme.
