A Review on use of Optimization Approaches for Energy Efficient Wireless Sensor Networks

Abstract
Nowadays, wireless sensor networks (EEWSNs) are widely being utilized in various fields such as internet-of-things, smart grids, military surveillance and health monitoring. The sensing nodes driven with limited energy supplies compelled the research community to propose optimization algorithms to achieve the smooth working of network for the longest achievable time. This paper reviews the implementation of optimization algorithms, heuristics or meta-heuristics, to achieve the energy efficient wireless sensor networks (EEEEWSNs) while fulfilling some constraints such as full coverage of all targets or whole area. Keywords - Wireless sensor networks, Energy efficiency, Heuristics, Meta-heuristics
