Proposed Simulator Based on Developed Lightweight Authentication and Key Management Protocol for Wireless Sensor Network

Abstract

Recently, wireless sensor networks is considered as an important part of the life. It becomes wide spread in different applications, such as military, medical and environment. In this paper, a modified lightweight authentication and key management protocol for wireless sensor network is introduced, employing the technique of Elliptic Curve Cryptography with Diffie-Hellman. In addition, A designed simulator that simulate the phases of authentication starting from base station tell the last sensor node. This simulator is produced to tackle the problem of lightweight protocol absence in the well-known simulators, such as NS2 and NS3. The modified protocol and the presented simulator are tested over different scenarios and the obtained results show the superior performance of them. Moreover, the results illustrate the high accuracy of the simulator and benefits of the modification on the lightweight protocol.
