Detection of Greedy Nodes over Wireless Sensor Networks

Http://www.ijesrt.com/issues%20pdf%20file/Archives%202013/april_2013/30.pdfWireless Sensor Networks (WSNs) are ad nodes to collectively gather physical or environmental conditions at diffe transmit data or information from different sensor nodes to a data repository on a server. The life span of the sensor network is limited to its left-over power. The wireless sensor nodes run through the batteries and deployed in hostile environment their battery is usually un the nodes do not forward the packets or data to other nodes in order to conserve their own resources such as energy, bandwidth and power. These types of nodes that act in a selfish manner to conserve their respective resources are called greedy nodes. This paper describes the various techniques to detect greedy nodes. It also discusses the key features of greedy nodes. The main goal of this paper
