A limelight on routing techniques in Wireless Sensor Networks with node mobility

Abstract

Routing in Wireless Sensor Networks (WSNs) is an emerging research area. This paper presents a survey of routing techniques in WSNs which support node mobility. In recent years, advancement in WSNs lead to the development of many routing protocols specifically designed for WSNs. The routing protocols discussed in this paper in general can be four main category such as Network structure, Communication model, Topology based and reliable routing. Existing routing protocols in WSNs mostly addresses static nodes. This paper presents routing protocols which support Node mobility and compares them with certain criteria. Finally, the paper concludes with future research related to network layer issues such as routing with node mobility.
