Abstract
Owing to the growth in several applications, Wireless Mesh Networks (WMN) is emerging as a vital technology for future wireless networks. Wormhole attack is one of the major security threats, which can disturb majority of routing communications, even when placed strategically. Therefore, a technique that can find wormhole-free routes in the network is required. In order to achieve this, in this paper, we propose a Monitoring Technique for Wormhole-Free Routing and DoS Attack Defense in WMNs. Initially, finite state model is applied where the node keeps the information about its sender and neighborhood receiver. Then, wormhole-aware secure routing is implemented to find wormhole free routes in the network. Finally, the priority mechanism is applied where the data packets are transmitted based on their priority. Based on the finite state model and priority mechanism, the malicious or wormhole nodes in the network are removed.
