Mobility Management In Wireless Sensor Network

Abstract: Wireless sensor network consist of sensors which senses some physical phenomenon then information is gathered and processed to get result. There are various issues regarding the mobility management such as coverage, connectivity, energy consumption, Location management. Wireless sensor networks are being used in different area such as in military, wildlife tracking, Industry security, disaster management. In many such tasks, node localization is very important. Node localization is required to report the origin of events, assist group querying of sensors, routing and to answer questions on the network coverage. So, one of the fundamental challenges in wireless sensor network is node localization. In real world if we want to implement some experiments with Wireless Sensor Network then are various practical difficulties. So to analysing its performance simulation essential for the study of WSNs. The ns-2 network simulator is one of the most widely used tool to investigate the characteristics of WSNs. This paper presents an extension of ns-2.
