ENERGY CONSUMPTION ANALYSIS OF WSN?S VARIOUS ENVIRONMENT FOR ADEQUATE KEY-REDISTRIBUTION IN DEF.

Increasing energy efficiency in wireless sensor networks is important because it is related to network lifetime. The sensor nodes are deployed in open environment, it causes threat like captured the sensor node. An attacker is possible to generate a false report using a compromised node and inject an attack on the network. False report injection attack causes fatal damage like false alarms, energy depletion, and other loss to users at the wireless sensor networks. To solve this problem Yu and Guan proposed dynamic en-route filtering scheme. It method detects and filters false reports early. Also, research has been conducted to increase energy efficiency through key-redistribution based on Dynamic en-route Filtering. In this paper, we analyze the average energy consumption of wireless sensor networks various environment for adequate key redistribution. The Experimental results show up to 32.75% energy efficiency improvement
