Integrated Network Topological Control and Key Management for Securing Wireless Sensor Networks

摘要

Wireless Sensor Networks (WSN) have appeared as one of the important fields at present due to their low-cost, self-organizing behavior, sensing ability in inconsiderate environments, and their huge application extent. One of the most challenging topics in relay network is security. The existing Network Topology Acquisition (NTA) processes for non transparent mode relay networks are not effective in providing the security features. At the same time, it is critical to provide privacy and validation in order to prevent information from relay networks. In the proposed system, key management is provided for privacy and simultaneously, validation for security measure is offered with relay nodes. Incorporated Network Topological control and Key management (INTK) scheme on the relay network provide the effective routing and security solution. INTK Scheme encompasses the incorporation of security and routing, active security, robust re-keying, low complexity and the multiple intensity of encrypt features in relay networks. Security scheme is designed with consideration of the multi cluster based topology control through a multiple intensity keying. The proposed security scheme has low communication energy due to its multi cluster-key executive. INTK Scheme acquires results on 4.5% improved security level with lesser execution time and communication energy consumption. A variety of numerical parameters are computed using ns2 simulator on existing NTA processes for non transparent mode relay networks and proposed INTK Scheme. INTK is highly realistic because it is intended to incorporate routing layer and security protocol without sacrificing energy.
