Poly Tree Construction Method to improve QoS in Wireless Sensor Networks

Abstract: The recent developments in Wireless Sensor Networks (WSN) suffer from efficient and secure transmission of packets. The common attacks in WSN are dropping/modification of data packets. Security to the data can be improved by disconnecting the droppers/modifiers form the network. This paper proposes a method to identify the nodes which are droppers and to disconnect them from the network. Simulation results are presented.
