Efficient utilization of energy of the network is one of the major issues faced by wireless sensor network, when sensors are placed in a hostile environment. One of the methods to solve this problem is to activate only a few sensors which satisfy the coverage constraints. This can be done by partitioning a set of all sensors into many subsets or sensor covers such that each sensor cover satisfies...
In this paper, a novel improved memetic algorithm is proposed for maximizing the sensor covers from the randomly deployed sensors in a hostile environment. This is achieved by optimizing the sensing range of the sensors by reducing the redundant target coverage and partitioning the set of all sensors into several subsets or sensor covers in such a way that each sensor cover monitors the entire targets...
Wireless sensor networks are employed in diverse range and are growing area of research and development due to the importance and necessity of applications. Wireless sensor networks depend on batteries with limited power and cannot be recharged or replaced often. Extending the lifetime of wireless sensor networks is a key issue that is being discussed in recent years. The lifetime of the wireless...
