无线传感器网络路由协议开发及改进

随着传感器网络研究的不断深入,实现和改进可实用性强的路由协议是一项具有现实意义的工作。基于真实的无线传感器网络,在MICAZ节点实现并改进了Flooding和Gossiping协议,首先设计了Flooding协议的报文格式和路由表,并开发了单源结点和多源结点路由协议,且利用序列号方法缓解了Flooding协议存在的报文内爆问题。同时,在多源的Gossiping协议中,设计了广播应答机制和随机转发选择机制以消除两个相邻节点的之间的数据循环发送。最后,基于组建的实际网络对两种协议改进后的性能进行了比较分析。

Implementation and Improvement of Sensor Networks Routing Protocols

The increasing research efforts of wireless sensor networks give rise to the implementation and improvement of routing protocols in wireless sensor networks. The Flooding and Gossiping protocols on real MCIAZ sensor nodes of our experimental sensor network are implemented and improved. the package format and routing table for Flooding, developing single-source and multiple-source Flooding protocols are designde, in whichthe sequence number to relieve the explosion problem therein is emplied. A broadcast-answer and randomly optional forwarding mechanism to avoid the repeated transmission between neighboring nodes are designed. Finally, the two improved protocols based on our deployed sensor network are compared and analyzed.
