| 摘 要： | 无线传感器网络中,传感器节点的能量、存储和计算能力有限,且无线传感器网络具有数据链路不对称、拓扑易变化等特点,设计节能可靠的网络协议是困难的。设计良好的网络协议不仅能降低网络的负载,还有助于节省传感器节点的能量,从而延长网络的生存周期。在无线传感器网络操作系统TinyOS平台上实现了基于RS纠删码的信息分发协议,并理论分析了在单跳情况下的协议性能,最后在仿真环境TOSSIM上模拟比较了在多跳、多路径情况下该信息分发协议和洪泛分发协议的性能。模拟仿真表明,提出的基于RS纠删码的信息分发协议明显减少了发送方发送数据包的数量,同时提高了节点的报文接收率,从而达到了降低网络能耗的目的。

| Abstract: | In wireless sensor networks(WSNs),the energy supply,storage capacity and computation power of sensor node are constrained.Furthermore,the irregular link and variable topology are common.Hence,it is difficult to design and implement a reliable and energy efficient network protocol.Well-designed network protocol can not only reduce network load,but also help to save energy of sensor nodes,therefore prolonging the network life.In this paper,an information dissemination protocol based on RS erasure codes was pr... |
