摘　　要：干扰严重影响移动Adhoc网络的网络吞吐量、能量消耗、网络寿命等性能.在已有基于邻居数目和分布位置的干扰模型基础上,进一步考虑各邻居上的通信量情况,提出通信量干扰模型.并在该干扰模型的基础上,提出一个通信量相关干扰感知路由TIR(traffic load-based interference-aware routing)协议.TIR通过在源节点和目的节点之间选择干扰最小的路径来降低数据包在转发过程中可能受到的干扰.模拟实验结果表明,所提出的通信量干扰模型符合移动Adhoc网络的特性,通信量相关干扰感知路由协议对网络寿命、通信延迟及吞吐量等网络性能有明显改善.The interference will greatly influence the performances of networks on its throughput, energy consumption, and lifetime in mobile ad hoe networks （MANET）. On the basis of the existing interference models founded on the number and distribution position of the neighbor nodes, the traffic load of neighbors is further considered and an interference model based on traffic load is proposed. Based on the new interference model, a traffic load-based interference-aware routing （TIR） protocol is proposed, which chooses the routing path with the minimal interference between the source node and the destination node to reduce the possible interference generated when a packet is being forwarded. The results of the simulations show that the proposed interference model based on traffic load suits the characteristic of the MANET, and the TIR protocol obviously improves the network＇s lifetime, communication delay and throughput.
