Sensor Positioning in Wireless Ad-hoc Sensor Networks with utilization of Energy

Manas Kumar Ray, Debaprasad Misra

Abstract


‘Localization’ is the most crucial and important issue in Wireless Sensor Network (WSN). It is use in various applications like positioning, tracing and routing. This paper is focused on coverage a space like military area, hospitals etc by using minimum number of sensor and optimized minimum energy. This paper, give a positioning algorithm, which estimate the position of sensors with minimum numbers and low energy consumption.. A sensor network deployment can usually be categorized as either a dense deployment or a sparse deployment. A dense deployment has a relatively high number of sensor nodes in the given field of attention while a sparse deployment would have fewer nodes. The dense deployment model is used in situations where it is very important for every event to be detected or when it is important to have multiple sensors cover an area. Sparse deployments may be used when the cost of the sensors make a dense deployment prohibitive or when you want to achieve maximum coverage using the bare minimum number of sensors. In this positioning algorithm dense deployment is used. But, future work is sparse deployment. It is assumed that the sensor nodes are static, they stay in the same place once they are deployed. In this algorithm each sensor node determining the location it needs to move, to in order of provide maximum coverage by utilizing minimum energy.
