Establishing Secure Event Detection with Key Pair in Heterogeneous Wireless Sensor Network

Abstract

How to improve the efficiency with security with the extension of lifetime of sensor nodes is the interesting area in the field of Heterogeneous Wireless Sensor Network (WSN). Key management is also an important concept of any secure communication. Expiring secure connections cause that connectivity in network decrease. For decreasing effect of compromising a node on expiring secure connections. The heterogeneity among sensor nodes help provides scalability, notable energy efficiency and security benefits. The previous protocol uses both probabilistic key pre-distribution in the lower tier of the network architecture and public key cryptography in the upper tier to distribute session keys. We proposed a protocol for key establishment which provides a high level of security and minimizes the resource consumption of the sensor devices. This provide a better suited for heterogeneous environment when applied with sensor devices. Finally our proposed protocol is better in comparison from others by applying different simulators.
