基于网络编码的多径路由策略

针对无线传感器网络节点能量受限制的特点,提出基于网络编码的多径路由策略.该策略在数据传输过程当中通过增加跨层协作机制,减少对单个数据包的依赖,降低数据包重传次数,使得网络带宽得到优化,同时数据在传输路径中进行随机编码使得数据包安全传输.分析表明,该策略可以保证数据传输的有效性和安全性.

A multi-path routing strategy based on network coding

Focus on the energy limited characteristic of the nodes in wireless sensor network. We propose a multi-path routing strategy based on network coding. By adding the cross-layer cooperation scheme, this strategy can bring down the dependence on the single data and reduce the influences which the link failure brings. So the network bandwidth is optimized, and meanwhile the random network coding operation on the transmitting data make the data packet transmitted safety. Analysis results illustrate that the strategy can guarantee the validity and the security of data transmission.
