基于无线网状网络的COPE优化方案

OPE bridges network coding with practice successfully. However, the requirement nodes need to encode packets in COPE limits the increasing of system throughput. In order to solve this problem, this paper proposes an evolved scheme(we call it ECOPE) based on COPE. By analyzing a common topology in networks, COPE lowers limit in encoding packets, increases the chance that packets in the output queue are encoded, accelerates the number of packets encoded, reduces transmissions per packet needs, and thus improves network throughput. In the meantime, by changing the number of output queue, we find the relationship of output queue and packets transport costs and take advantage of this to cut down the cost.
