Recent technological advances have enabled distributed information gathering from a given region by deploying a large number of networked tiny microsensors which are low power devices equipped with programmable computing, multiple sensing and communication capability thus forms Wireless Sensor networks. Directed Diffusion is a data centric routing protocol in Wireless Sensor Networks (WSN). It is a reactive protocol which creates routes based on needs. Sensed datas are stored in attribute value pairs. A Sink request data by sending interests. The interest messages are flooding through the network and are added to each nodes interest cache. The data that match the interests are sent towards the sink. However, there is very little research addressing the impact of mobility on this class of routing protocols. In this paper, we address the behavior of a Directed Diffusion routing under different scenarios.
