An Optimized Energy Saving Model for Hybrid Security Protocol in WMN


Wireless mesh network (WMN) is an emerging field of research with a large number of applications and associated constraints. WMN is used as a new wireless broadband network structure which is completely based on IP technologies. It has the ability to produce high speed and wide area of coverage, and it also provides a high capacity for handling the nodes. To help authenticate messages, identify valid nodes and remove malevolent node. Security and privacy are two major problems in WMN. Unfortunately, in mesh networks most privacy-preserving schemes are vulnerable to attacks. The most dangerous attack to be noted in mesh network is node impersonation attack which makes them more insecure. WMN is said to be an emerging wireless broadband network structure, where it is completely based on the IP technologies. The mesh routers and clients play a vital role in the mesh networks where they act as a backbone and help the mesh networks to achieve their target in an efficient way. The important factor in the wireless mesh network is to provide a trusted handoff between the nodes, and they need an access authentication effectively. This area can be considered as the vulnerable one, and there is a chance for some attacks which makes the network unstable. Achieving the seamless handoff is a complex case in every dynamic heterogeneous wireless mesh network. This is because providing a security for such kind of structure is very difficult and the existing procedure for providing security for heterogeneous network gives protection for certain types of attacks. In this paper, we use an optimization algorithm for finding the best position for deploying mesh routers and for developing a hybrid and secured model for detecting node impersonation attack by combining ECDSA with CHAP. We also show how our proposed model can handle the throughput, authentication delay, etc., without facing any problem such as energy consumption and delay.
