摘要
针对无线传感器中的节点调度传输问题,提出了一种基于网络编码的协同点对点信息交换算法。由于该算法不仅能够充分利用无线信道的广播特性,而且使用了协同点对点信息交换,从而有效地弥补了PIE算法在数据包的个数大于节点数目的情况下,性能不理想的缺陷,实现了传输次数的减少。仿真结果表明,所提算法的传输有效性明显地优于PIE算法和最少优先算法。
Aiming at the peer scheduling problem in wireless sensor network, a cooperative peer-to- peerinformation exchange algorithm based on network coding is proposed. This proposed algorithm not only makes fujiuse of broadcasting characteristics of wireless channel, but also uses cooperative peer- to- peer informationexchange, so it can effectively make up for the shortages of PIE algorithm and reduce the number oftransmissions. Experimental results demonstrate that the performance of the proposed algorithm is better thanthat of PIE algorithm and rarest first algorithm.
