| 摘 要： | 该文提出了一种基于信道阻力的Ad hoc网络多路径动态源路由算法。算法中定义了信道阻力的概念，并以信道阻力为依据来进行多条路径的流量分配，由于信道阻力计算中综合考虑了链路质量的各个度量参数，因此能够根据各条路径的传输能力合理分配数据流量。NS2环境下的仿真表明，新算法能够有效地平衡网络负载，提高网络的吞吐量。

| Abstract: | A multipath dynamic source routing algorithm based on channel resistance is presented. In the algorithm, the concept of channel resistance is defined and used for distributing data flow between different paths. Because the parameters of link quality are comprehensively considered in calculating channel resistance, the algorithm can reasonably distribute data flow to different paths according to their transmission ability. Simulations under NS2 environment prove that the new algorithm has better performance in balancing the network load and improving network throughput. |
