An Efficient Approach for Data Aggregation Routing Using Survival Analysis in Wireless Sensor Networks

Wireless Sensor Network (WSN) is a collection of small sensor nodes with a communications infrastructure to achieve mutual communication and to monitor and record conditions at diverse locations. The major constraints of WSN are limited availability of power and it is prone to frequent node failures. In order to prolong the lifetime of the sensor nodes, the sensor data should efficiently reach the base station and there should be a reduction in message transmission, which consumes the majority of the battery power. Aggregation of data at intermediate sensor nodes helps in saving the energy that would be spent if the nodes send directly to the base station.
