在动态网络拓扑中,AODV协议通过数据源节点S泛洪广播RREQ消息请求到任意目标节点D的路由,而在无线体域网络中,只有一个sink目标节点,除最短跳数路由上的节点外,其他参与RREQ接收和转发的节点浪费了能量。提出了一种能量平衡的无线体域网络AODV多播路由发现协议,通过在节点广播的hello消息中增加到sink的最小跳数hops、到sink的下一跳节点next和节点本身是否具备转发能力isforward 3 个参数,只选择能到达sink节点的邻居节点参与转发RREQ消息,变广播为多播,有效地降低了路由发现的能量开销,并通过能量平衡延长了WBAN的使用寿命。性能分析与模拟实验表明,该协议在RREQ数量、数据传输率和能量消耗等方面优于相似协议EAAODV。
In AODV protocol with the dynamic topology networks,the source node S requests a route to an arbitrary destination node D with flooding broadcast the RREQ message,but there is only one destination node sink in a WBAN,other nodes involved in receiving and forwarding RREQ have wasted energy except the nodes on minimum hop count routing.An energy balance AODV protocol with multicast route discovery for wireless body area networks was proposed,it increased the minimum hop count to sink hops,the next hop node to sink next and the node itself has the forwarding capability isforward three parameters in a hello message,and selects neighbors which could reach the sink only to participate in forwarding the RREQ message.This protocol effectively reduces the energy cost of the routing discovery through changing the broadcast to multicast,and prolongs the service life of WBAN with energy balance.The performance analysis and simulation experiment indicate that the proposed protocol is more advantaged than similar EAAODV in the number of RREQ,packet delivery ratio and energy consumption.
