A Wireless Sensor Network (WSN) is a wireless decentralized structure network consists of many nodes. Nodes can be fixed or mobile. WSN applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in WSN. Wireless Localization used to determine the position of nodes. The precise localization in WSNs is a co...

Wireless sensor networks consist of a network in which node are spatially distributed. These sensor nodes communicates with each other for transferring data from one node to another. These sensor nodes while transfer of data consumes energy. So the energy consumption is high in wireless sensor networks. To reduce the energy consumption the compressive sensing method is given known as compressiv...

Simulation results show that the algorithm in this...

An ad-hoc wireless sensor network is also called self-organized networking that wireless sensor nodes can automatically communicate for each other. Therefore, each sensor node is no need for the information such as location of each sensor. Similarly, it consumes much energy on the information exchanged of each sensor node in order to maintain the entire ad-hoc wireless sensor network alive. The...
