A research on controlling topology of wireless sensor networks against node based attacks

Abstract

The topology design with survivability and reliability is a crucial aspect in wireless-sensor networks. Controlling the topology is very important as it can affect the efficiency of Wireless-Sensor Networks (WSN).To address the problem, an approach on energy efficiency is proposed on scale free networks. The nodes in the network are evenly distributed to accommodate scaling of the network. The quality parameters like energy and load balance should be captured by the network, as factors like residual energy of the node and node degree are taken into consideration. Arrangements are made to look at the network in a practical way and core functionality of the network is not disturbed. Strategies are deployed to make the network robust for node based random and malicious attacks. In this Survey, we concentrate on the study of topology control techniques with energy based parameters, change the topology of the network to improve efficiency of network in terms of network lifetime.
