Priority Based Trust Efficient Routing Using Ant Colony Optimization for IoT-based Mobile Wireless Mesh Networks

Abstract

Wireless Mesh Networks (WMNs) are considered as an important structure for the next generation wireless networks that have numerous nodes organized in the mesh topology. In WMN, the data packets are forwarded through the multi-hop model. Nowadays, the combination of mesh clients with the Internet of Things (IoT) is gaining substantial importance for connecting numerous machines and it is used to acquire faster coverage. Moreover, the nodes in the WMN are susceptible to the malicious nodes which transmit the compromised and manipulated data to the destination. In this research, the Priority based Trust Efficient Routing using Ant Colony Optimization (PTERACO) is proposed to achieve data privacy and reliable routing over the WMN. Subsequently, Advanced Encryption Standard (AES) and Rivest Cipher 6 (RC6) are used to provide added security to the data. The PTER-ACO is analyzed by means of energy efficiency, network throughput, Packet Loss Rate (PLR), computational overhead, and latency. The existing methods such as Improved version of the Dijkstra Algorithm (IDA), Round Trip Time (RTT) based detection and Robust and Trusted Scheme (RTS) are used to evaluate the PTER-ACO, against these methods. The PLR of the PTER-ACO method is 21 % for 10 malicious nodes, which is less when compared to the IDA, RTT and RTS
