一种新的均衡流量提高网络能量效率的Ad hoc网络路由建立算法

能量问题是Ad hoc网络中的一个重要问题，该文提出了通过均衡流量提高网络能量效率的TBDB路由建立算法。该算法在路由建立时对可选的路径集合进行限制，根据节点在饱和状态时归一化吞吐量的值，分别设定链路层队列中数据长度的门限值和节点连接度的门限值，收到路由请求的节点，根据门限值和节点的当前状况对节点是否响应收到的路由请求做出判决，从而调节了网络中节点的负荷，均衡了网络中能量的消耗，避免节点长期处于重负荷状态，保证了当前正在进行的传输。分析和仿真表明该算法在均衡流量的同时，也将网络中能量的消耗均衡地分散于网络各个部分，改进了网络的性能。仿真结果表明该路由算法提高了网络的吞吐率和能量效率，并且降低了平均端到端的延时。

A New Route Setup Scheme for Ad hoc Networks to Improve Energy Efficiency

Energy problem is very important in Ad hoe networks due to energy-constrained. In this paper, a traffic balanced route setup scheme, called TBDB, is presenred to improve energy efficiency. TBDB routing setup scheme decides whether to reply the route request by the connected flows of the node. Both of them have own threshold values and make routing decisions by the status of the node. The threshold values can be obtained by the normalized throughput values under saturated status. Analysis and simulation results show that both of them balance the energy consumption and the traffic of networks, improve the energy efficiency greatly, and decrease the average end to end delay.
