Abstract: In view of cooperative diversity for Wireless Sensor Networks(WSNs), the symmetric cooperative model combining nodes energy consumption with throughput is discussed. Based on Raiffa-Kalai-Smorodinsky Bargaining Solutions(RBS), the symmetric cooperation problem is recast into a bargaining problem. A WSN symmetrical cooperation strategy to improve the network transmission efficiency is proposed. The symmetric cooperative model is analyzed, which consists of [n] sensor nodes and one sink. The implementation process for an optimal bandwidth allocation strategy is discussed based on RBS. The simulation results show that this symmetric cooperation strategy can improve the sensor node’s transmission efficiency dramatically.

摘要: 针对无线传感器网络(WSN)的合作多样性问题,对结合节点能耗和吞吐量的对称合作模式进行了讨论。基于Raiffa-Kalai-Smorodinsky议价解(RBS),将对称合作问题转换成议价问题,提出了一种提高网络传输效率的WSN对称合作策略。分析了由[n]传感器节点和一个sink 组成的对称合作模型,并在此基础上,讨论了RBS最优带宽分配策略的实现过程。仿真结果表明,该对称合作策略可以大大提高传感器节点的传输效率。
