A Review: Optimization of Energy in Wireless Sensor Networks

Wireless Sensor Networks have become an important research topic in last year. WSN is a collection of tiny, large number of densely deployed sensor node; these sensor nodes are smart, effective which is very powerful and versatile networking where traditional wired and wireless networking is unable to deploy. These sensor nodes have limited transmission range, processing and storage capabilities as well as their energy resources. Routing protocols for wireless sensor networks are responsible for maintaining the energy efficient paths in the network and have to ensure extended network lifetime. In this paper, we propose a new approach to provide multiple routing paths using an Ant Colony Optimization (ACO) algorithm. Ant Colony Optimization based routing algorithms have been proposed to solve the routing problem trying to deal with these constrains. This paper will find an energy efficiency path in the WSNs using a method is based on Ant Colony Optimization (ACO) algorithms, aiming to minimize the consumption of power, improve fault tolerance, and length the network lifetime. We conclude that the proposed protocol effectively extends the network lifetime with less consumption of energy in the network.
