能量感知多路径负载均衡路由算法

针对移动自组织网络的网络拥塞问题,基于能量感知技术并结合负载均衡和拥塞控制方法,提出了一种能量感知多路径负载均衡路由算法。该算法利用能量感知选择满足条件的节点作为路由节点,建立多条连接源节点和目的节点的有效路径;同时分析路径的跳数、节点缓冲区的占用情况,从有效路径中选出用于传输的最优路径;然后对最优路径上的节点和路径的负载情况进行建模分析,当节点能量、节点负载、路径负载到达设定的阀值,就将最优路径上的流量分流到其它路径。利用NS2仿真软件,在不同的场景下对该算法以及QMRB、SMORT进行仿真测试。仿真结果显示:提出的算法与其它路由算法相比将网络性能提升了近20%,起到了均衡负载的作用,能有效地解决网络拥塞问题。

An Energy-aware Multipath Load Balancing Routing Algorithm

Aimed at the network congestion problem for mobile ad hoc network based on energy aware technology and load balancing combined with congestion control method, this paper proposes an energy-aware multipath load balancing routing algorithm. The algorithm utilizes energy-aware for selecting the node of satisfying the conditions as the routing node to establish multiple effective paths of connection source node and destination node. At the same time, the paper analyzes the number of hops in the paths and the buffer occupancy of the node, selects the optimal path for transmission from the efficient paths, and establishes a model of the load of nodes and paths on the optimal path. When the energy of node, the load of node and the load of the path reach the set threshold, the flow of the optimal path is diverted to other paths. The simulation software NS2 is utilizes for testing this algorithm, QMRB and SMORT in different scenarios. The simulation results show that the proposed algorithm improves the network performance by about twenty percent compared with the other routing algorithms.
