Abstract

Abstract: This paper proposes an improved DRR algorithm which aims at deficiency of Directional Rumor Routing（DRR）.In contrast to DRR，there are two differences：（1）IDRR introduces virtual sink node and virtual source node to help the delivery of event agents and query agents.（2）After obtaining location information of the sink node，IDRR employs the geographical information of the sink node and the residual energy of other nodes to make the routing decision from the source node to the sink node.The simulation results show that IDRR can increase the probability of event agents hitting related query agent，prolong the network lifetime，and balance the energy consumption more effectively?than traditional DRR algorithm.

摘要： 针对定向谣传路由DRR算法的不足，提出了改进的算法模型IDRR，主要体现在以下两点：（1）在DRR算法的事件agent和查询agent发送方向上引入了虚拟Sink节点和虚拟Source节点。（2）获得Sink节点地理位置信息以后，利用Sink节点的地理位置信息和节点的剩余能量来确定一条优化的数据传输路径。仿真结果表明：改进后的IDRR算法提高了事件agent和查询agent的相交概率，均衡了网络节点的能量消耗和延长了网络的生命周期。
