无线传感器网络分层带宽自适应路由协议

在无线传感器网络(WSNs)中,节点能量使用严格受限,限制了网络的使用寿命。固定环带宽度的分层路由协议是一种有效的解决方法。在此基础上,提出了一种引入环带宽度自适应调整的路由机制。该机制根据节点剩余能量和传输数据能耗自动调整环带宽度,并决定节点是否参与网内数据报文的传输。采用Matlab作为仿真工具对该路由机制进行了仿真分析,结果表明:该算法通过调整环带宽度的方式能够有效延长网络使用寿命和维持网内负载均衡。

Hierarchical bandwidth adaptive routing protocol in WSNs

In wireless sensor networks（ WSNs）,energy of node is severely limited,which restricts lifetime of WSNs.Hierarchical routing protocol is an efficient method to prolong lifetime of WSNs.Based on these kinds of protocol,propose a routing protocol that can adjust the bandwidth automatically.The presented mechanism can not only automatically regulate bandwidth according to node residual energy and energy consumption of data transmission,but also decides whether nodes will take part in transmitting packets in network.Simulate the proposed mechanism by using Matlab,the results show that the algorithm can efficiently prolong lifetime and keep load-balance of WSNs by regulating bandwidth.
