Maximizing Security and Advancing Performance of a Wireless Mesh Network by Implementing a New Approach “Reference Broadcast System”

A wireless mesh network can be seen as a special type of wireless ad-hoc network. A wireless mesh network often has a more planned configuration, and may be deployed to provide dynamic and cost effective connectivity over a certain geographic area Wireless mesh networks often consist of mesh clients, mesh routers and gateways. In wireless mesh network security of network is one of most concerned area. Here we have proposed a new approach to maximizing security of a network basically we have worked on DOS in which we have shown applied our approach in wormhole attack. The wormhole attack is one of the most severe security attacks encountered in wireless ad hoc networks. It can significantly disrupt the communications across the network, is hard to detect and can be implemented without having a cryptography key or knowing the network routing protocol. We have proposed approach called RBS (Reference Broadcast System) in this approach relative velocity of various nodes is get compared. More precisely there is a reference node in network and when a malicious node attacks into the network than velocity of a malicious node get drastically changed in comparisons of other nodes with respect to that reference node this is happened because a malicious node attacks from outside of the network so it becomes easy to detect that node on the basis of velocity. We have performed our analysis with wormhole attack and without worm hole attack and our results proved the significance of the approach that we have applied here. We have analyzed our result on the basis of various parameters and improvement in the network has been verified by simulated results in Xgraph.
