摘要
针对AOMDV协议只使用主路径传输数据,导致备用路径未能得到充分利用以及网络负载失衡的问题,本文提出一种LBAOMDV(Load Balanced AOMDV)协议。该协议在AOMDV协议的基础上使用基于路径长度、路径使用次数以及路径状态的分流传输机制在多条路径上同时传输数据以均衡网络负载,当网络中的节点负载过重并通过预先设定的阀值时将触发拥塞预警机制以减少通过该节点的数据流量,从而进一步达到网络负载的动态均衡。
AOMDV routing protocol transmits data using only the primary path,does not take full advantage of the al-ternate paths,and does not balance the network load.To solve this problem,we propose a LBAOMDV（Load Balanced AOMDV）protocol.The proposed protocol uses shunt transmission mechanism which based on path length、path used times and path state to make data transmit in multiple paths at the same time,it will balance the load,when the load of an node in the network increases beyond a defined threshold,it will trigger congestion warning mechanism to reduce the data traffic through the node,it will further achieve dynamic load balancing.
