AODV(Ad Hoc on-demand distance vector)路由协议是Ad Hoc网络中一种具有代表性的按需路由协议。传统的AODV是以“最小跳数”为参数建立和更新路由的。随着网络负荷的增加,以这种方式建立和更新路由容易引起网络中部分节点较其它节点更多地参与通信,在这些节点发生拥塞的可能性将更大,频率将更高,这会增加网络能耗,缩短网络生存时间。针对这一问题,笔者提出了通过控制拥塞对AODV进行节能改进的一种算法—Lengthen Lifetime AODV(LLAODV)。
AODV (Ad Hoc on-demand distance vector) routing protocol is a typical on-demand routing protocol in Ad Hoc networks. The traditional AODV is based on the “minimum hops” as a parameter to establish and update the routing. As network load increases, establishing and updating routes in this manner tends to cause some nodes in the network to participate more in communications than others, with a greater probability of congestions at these nodes and a higher frequency, which increases Network energy consumption, shorten network life time. In response to this problem, the author put forward an algorithm for energy saving improvement of AODV by controlling congestion - LENGthen Lifetime AODV (LLAODV).
