摘　　要：动态源路由(Dynamic Source Routing,DSR)是移动自组织网络(Mobile Ad-hoc Networks,MANETs)的典型路由。但是,DSR路由总是选择最短路径进行通信,导致网内流量的不平衡。为此,提出基于能量感知和低拥塞的DSR改进路由(Energy-aware and congestion-less-based DSR improved routing,EACL-DSR)。EACL-DSR路由在路由发现阶段同时考虑了拥塞率和能量效率,其目的在于降低拥塞概率,并依据节点能量和拥塞率这两项信息选择合适的下一跳转发节点,提高路由稳定性。仿真数据表明,提出EACL-DSR路由提高了数据包传递率和吞吐量。Dynamic Source Routing( DSR) is one of the well-known protocols in MANETs. However,DSR opt for shortest paths for communication during the path selection process,which may lead to an unbalanced traffic flow across the network. Therefore,the DSR is improved,and Energy-aware and congestion-less-based DSR improved routing( EACL-DSR) is proposed in this paper. We consider routing in view of congestion and energy efficiency at the same time. The aim is to select a route to minimize the chances of congestion. The intelligent node selection process of ECL-DSR selects only suitable nodes in terms of energy and network load in order to improve the stability of routing. The simulation results show that the proposed routing protocol improve the packet delivery ratio and throughput.
