An Energy Efficient WSN through Watchdog Optimization

Muhammed Swalih.K.T, Akila.M

Abstract: The technique of using watchdog is a fundamental building block to many trust systems that are designed for securing wireless sensor networks (WSNs). But this kind of technique consumes much energy and hence largely limits the lifespan of WSN. Although the researches in this field realized the importance of trust systems efficiency in WSNs and proposed several solutions which are not sufficient for achieving maximum efficiency. So they have overlooked to optimize the watchdog technique, which is perhaps among the top energy consuming units. The inefficient use of watchdog technique is used in existing trust systems. Thereby this proposed method is a suite of optimization methods to minimize the energy consumption of watchdog usage, while keeping the security of whole system in a sufficient level. Here the concept contributions of this project consist of theoretical analyses and practical algorithms, which can effectively and efficiently schedule the watchdog tasks depending on the sensor nodes locations and the target nodes trustworthiness. Implementing and simulating the project is done using Network simulator, to assess its real time working and performance evaluation
