Evaluation of Directed Diffusion Protocol for Mobile Sensor Networks

چکیده
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 data’s 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 node’s 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. Keywords— Directed diffusion, Drain rate, Power Consumption, Wireless Sensor Networks.

Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
