AVOIDANCE OF DATA REDUNDANCY IN WIRELESS SENSOR NETWORKS

Sensor nodes are mobile in nature in some Wireless Sensor Networks (WSN). Due to this nature there is no guarantee of reliable data reception. To ensure this, sensor nodes are deployed densely in monitoring environment. The node in the particular region senses the same kind of information and then forwards it to the sink or base station. This redundant information provides reliability with the power and memory constraints. The main goal of this paper is to avoid the data redundancy and to reduce the energy consumption and memory space. It uses the match detection technique to avoid the redundancy problem. Through analysis and simulation, this paper demonstrates that the proposed technique is effective and efficient for avoiding redundancy in sensor networks.
