Routing Protocols for Energy Efficiency in WSNs: A review

Abstract

Wireless sensor networks (WSNs) is a significant part of networking area. They are cheap, efficient, and small, they are become more and more important for several applications. However, with the widespread use of applications that rely on wireless sensor networks, they continue to suffer from limitations such as data routing and security. WSNs can be used for several applications. Nodes of Sensor work on batteries. It is impossible to charge or replace the battery in some applications. For that purpose, optimal use of node’s energy is a key issue in the network. Routing is a significant challenge to extend the lifespan of network. Several protocols are implemented in WSNs. In this study, a survey on clustering techniques, present a characteristic and requirements routing design of WSNs. Result of this study shows how to solve some of these problems. WSN routing protocols have to ensure shortest paths, minimum energy consumption, less delay and maximum lifespan of network.
