摘要： 无线传感器网络能够实时的监测、感知和采集各种环境或监测对象的信息，其关键技术之一就是路由算法及实现。本研究提出一种改进的定向扩散路由算法，通过分析兴趣扩散的深度、邻居节点的梯度及接收信息的效率，选取最优的节点用以建立数据传输路径。并在网络仿真工具OMNET++环境下实现了对该协议的仿真，仿真表明该协议具有很好的性能，能大大缩短路由建立的时间，提高数据传输的速度。

Abstract: Wireless sensor network (WSN) can be employed for testing，sensing，collecting and processing real-time information of monitored objects，and one of the key techniques for its successful application is the routing algorithms. An improved directed diffusion routing mechanism is proposed in this paper. By analyzing the height of interest diffusion, the gradient of neighboring nodes and the efficiency of receiving message, the optimal set of nodes are determined for building data transport route. Simulation of the proposed routing protocol is implemented with OMNET++ software and the results indicate the protocol have good performance with decreased time for establishing the route path and increased speed of data transmission.
