Wireless Sensor Networks: A Study on Energy Optimization Techniques

Abstract

WSN’s (wireless sensor networks) are battery powered nodes and the key aspect of this article is to minimize the energy efficiency and increase the lifetime of nodes. The wsn’s assess the energy phases of each node in the networks. These sensor nodes are small, economical and limited resource devices that sense the atmosphere which interact with each other. The lifetime of these nodes are completely depends on energy utilization. In WSN sending and receiving data speeds are varied node to node. Energy optimization techniques are used to enhance the energy and also enhance the lifetime of sensor nodes. This study is broadly based on different techniques which will help to avoid energy wastage of network nodes and its success rate. Several optimization techniques are proposed for developing network lifetime and power utilization like, GA, ACO, ABC, PSO, LEACH, HEED, TEEN and PEGSIS.
