Data Security in Wireless Sensor Networks Using a Star Topology Approach

Security has become one of the major issues for data communication over Wired and Wireless sensor networks. Consider wireless sensor networks while transferring the data it can be attacked by different kinds of attacks such as compromised node, denial of service attacks. We agree that existing multi-path routing approaches are vulnerable to such attacks, mainly due to their deterministic nature. By considering the routing algorithm, it can compute the same routes known to the source, therefore all information sent over these routes. To secure the data from these attacks we can generate randomized multipath routes. These routes are taken by the shares of different packets change over time. While sending the data the randomized multi path routes include the same routes. In this paper, “instead of selecting self nodes “we generate dynamic multi path routing in which the shares of different packets are taken and send to the destination. We develop efficient topology for delivery the data in secure manner. The experimental results show that topology out performs traditional schemes in terms of CPU cost, minimization of retransmissions.
