Intelligent Decision for Dynamic Fuzzy Control Security System in Wireless Networks

Abstract

Security in wireless networks has become a major concern as the wireless networks are vulnerable to security threats than wired networks. While elliptic curve cryptography (ECC) prominently offers great potential benefits for wireless sensor network (WSN) security there is still a lot of work needs to be further improved due to WSN has very restraint running conditions such as limited energy source, capability of computing, etc. It is well known that scalar multiplication operation in ECC accounts for more 80% of key calculation time on wireless sensor network motes. In this paper we presented an intelligent decision for optimized dynamic window based on our previous research works. The whole quality of service (QoS) has been improved under this algorism in particularly the power consuming is more efficiently. The simulation results showed that the average calculation time, due to intelligent decision system and the fuzzy conditions decreased from previous 26 to current 9 as a whole the calculation time, decreased by approximately 17.5% in comparison to our previous algorithms in an ECC wireless sensor network.
