Data Aggregation over Geographical Area Coverage in Wireless Adhoc and Sensor Networks

Wireless sensor networks has become envisage for various purpose in all the fields of technology. Random deployments are a fundamental crisis to realize coverage and/or connectivity in sensor networks. Path-Trace-Back protocol is proposed proficiently to preserve the data at specific geographic area coverage in a network with node mobility in nature. This scheme can turn out to be more difficult for isolated places in the area where only low density of sensor nodes exist. To tackle this problem, the path-trace-back scheme, initially permits a mobile node to periodically return the data to fixed location about the trail area coverage whose packets travel from the region of source and utilizes the reported trail to enhance the path revisited. Based on the optimality conditions, we devise the distance based and trail based approach for an explicit area using Path-trace -- back protocol that shows an enhancement of 80 percent against the distance based and Max Propagation protocol. The result obtained achieves higher performance when the region of coverage area is less connected.
