SECURE AND EFFICIENT WATCHDOG OPTIMIZATION FOR CLUSTER-BASED WIRELESS SENSOR NETWORKS

Abstract

Watchdogs are an effective mechanism to detect selfish and malicious attacks from computer networks. In networks, such as MANETs, attack analysis and detection is a more importantfor the whole network. Watchdog systems detect the misbehavior and that neighbor node by using data collection and analysis, so accuracy, less delay and effectiveness are achieving much more security and performance in wireless sensor networks.In previous process watchdog has inefficient trust system for security in the network.In this paper, we propose a watchdog technique for improving the trust system in networks by using effective optimization methods. To expose this method,:we can achieve better efficiency compare to existing and minimum energy cost for using watchdog technique and also keeping sufficient level security. In our contributions of the proposed method, it consists of theoretical analyses and practical algorithms. Using this watchdog approach the detection of misbehaved nodes is reduced, sufficient security, less energy consumption and the overall accuracy increased.
