A HEURISTIC TO ACHIEVE MAXIMUM LIFETIME AND TARGET COVERAGE IN WIRELESS SENSOR NETWORK

S.Jayarani , K.Vinotkumar

ABSTRACT Network lifetime plays an integral role in setting up an efficient wireless sensor network. This proposed method was able to achieve the theoretical upper bound. The objective of proposed system is contained as twofold. The first one is to deploy sensor nodes at optimal locations such that to achieve the theoretically computed network lifetime is Maximum. The another fold is to schedule these sensor nodes such that the network attains maximum lifetime. Thus, the overall all objective of the proposed system is to identify optimal deployment locations of the given sensor node with a pre-specified sensing range, and to schedule them such that the network lifetime is maximum with a required coverage level. An effective approach to extend the network lifetime is to schedule the active states is sensor. In this proposed system Artificial Bee Colony (ABC) algorithm used for sensor deployment problem followed by a heuristic for scheduling. The ABC approach is used to minimize the energy consumption. A comparative study shows that artificial bee colony algorithm performs better for sensor deployment problem. Keywords:- Artificial Bee Colony, Sensor Network, Deployment, Energy Consumption.
