Comparative Review of Routing Protocols for Energy- Efficient and Security in Wireless Sensor Network

Abstract

Recent developments in advanced wireless system have resulted in several improvements in the deployment of sensor networks communicating wirelessly. In order to monitor and control physical processes or parameters in a given system or environment, sensing device(s) is/are required. Thus, wireless sensor network (WSN) is a connection of sensor nodes designed to sense data from environment where they are deployed according to application. One of the most critical issues in WSN is the energy-efficiency. As a fundament factor to effective WSN installation, energy-efficient in the operation of WSN is a necessary topic that has attracted great attention in wireless sensor applications. Another important issue is the security of the WSN. As a result of the sensitive of data gathered by WSN, securing its nodes especially the sink node, will help prevent attackers from stealing important data that require high confidentiality in such areas as military applications. This paper has reviewed some of the routing protocols that have been designed for energy-efficient operation to prolong the lifetime and provide security for nodes of WSN
