面向无线体域网的能耗控制路由算法研究

Research on Energy Consumption Control Routing Algorithm for Wireless Body Area Network

无线体域网传感器节点的能量是有限的,如何优化体域网的路由选择,降低网络能耗成为无线体域网路由算法设计的关键。目前,常用于无线体域网的动态源路由算法DSR虽能够顺利完成数据传递,但存在能耗较高的问题。因此,在DSR的基础上,提出了一种基于能耗控制的路由算法ECC-DSR。该路由算法采用节点独立性传输链路,并综合考虑路由路径跳数、节点发射功率与剩余能量,动态调整路由,从而使路由在传输数据时可以充分利用网络中的资源。仿真结果表明,ECC-DSR协议能够降低无线体域网的能耗,延长网络生存期。

Because the energy of sensor node of wireless body area network is limited,so how to optimize the routing to reduce network energy consumption becomes the key to WBAN routing algorithm design.At present,although the dynamic source routing algorithm（DSR）,which is commonly used in WBAN,can successfully finish the process of data transmission,there is aproblem of high consumption.Therefore,the energy consumption control routing algorithm which is based on DSR was proposed in this paper.The routing algorithm uses Node-Disjoint and takes into account the number of hops of the routing path,the node of the transmit power and the residual energy.Based on those above people can adjust the route dynamically,so that data transmission can make full use of the resources in the network,simulation shows that ECC-DSR can reduce energy consumption and prolong WBAN lifetime.
