An Authenticated Trust Based Security Mechanism for Video Transmission in Wireless Mesh Networks

Recently Wireless mesh networks (WMNs) have emerged as a key technology to meet the challenges in multimedia networks. Mostly the WMN are multi-hop in nature and in order to achieve availability, the routing protocols must be robust against both dynamically changing topology and malevolent attacks. In WMN, Security is one of the primary concerns due to the open nature and to ensure security in wireless mesh network (WMN) is a critical issue. To address the security vulnerabilities, though several secure routing protocols have been proposed but still there exist problems. In order to overcome this, a Secured Optimal Trusted Multipath Routing Protocol (SOTMRP) using fuzzy is proposed which is an extension of our previous work that improves the security in path selection. To ensure security in video transmission an Improved Dynamic DES algorithm (IDDES) is proposed and also to authenticate the destination an authenticated 3-way hand shaking mechanism is implemented in our system. The Simulation results show that the secured SOTMRP outperform well than other trust models by considering the various parameters such as Average throughput, Packet Delivery Ratio, Energy consumption, Trust value computation and Control Overhead.
