无线传感器网络中存在大量数据,数据融合及网络优化可以有效降低网络能耗,提升网络吞吐量。由于无线传感器网络自身的广播特性,在无线网络中应用网络编码可以带来吞吐量提升等性能增益。考虑将N个源节点的K个数据发送到D个不同目的节点的情况,源节点在自身可用路径上分配流量,利用博弈论研究无线传感器网络流量分配问题,提出了一种动态控制方案,源节点根据效用函数调整路径流量分配,以增加网络编码机会,从而降低网络能耗。理论分析和仿真结果表明,该方案是稳定、有效的。

Data integration and network optimization play an important role in wireless sensor network which is data-centric. Network coding has been used as an efficient method to improve network throughput over wireless environments. The problem of broadcasting K different contents to D destinations from N sources in wireless network was considered. A dynamic control scheme that allows sources split traffic was proposed. The scheme adjusts the traffic based on the utility function to increase the number of coding opportunities. The theoretical analysis and simulation results show that the proposed scheme is stable and effective.
