JANUS: A Framework for Scalable and Secure Routing in Hybrid Wireless Networks

Abstract

In this paper we introduce JANUS, a framework for scalable, secure and efficient routing for hybrid cellular and Wi-Fi networks. JANUS uses a scalable routing algorithm with multiple channel access, for improved network throughput. In addition, it provides protection against selfish nodes through a secure crediting protocol and protection against malicious nodes through secure route establishment and data forwarding mechanisms. We evaluate JANUS experimentally and show that its performance is 85% of the optimum algorithm, improving with a factor greater than 50% over previous work. We evaluate the security overhead of JANUS against two type of attacks: less aggressive, but sufficient for some applications, selfish attacks, and purely malicious attacks.

Cross-Layer Metrics for Reliable Routing in Wireless Mesh Networks

“…The secure message transmission (SMT) protocol proposed by Papadimitratos et al in [9] exploits multiple node-disjoint paths to increase the end-to-end delivery rate using a message dispersion scheme that enables the destination to recover the information contained in data packets by increasing its redundancy. JANUS [16] provides a secure and reliable routing framework for hybrid cellular and Wi-Fi networks. In [17], the authors propose ARCS, an innovative routing protocol that enforces the cooperation among selfish nodes, limiting at the same time the damage caused by malicious devices.…”

Research on Selective Forwarding Attack Detection Scheme in Wireless Sensor Networks

“…Selective forwarding attack and transmission failure share the same characteristics of packets loss. JANUS scheme is proposed to detect unreliable links using response mechanism [5]. However, malicious node may return a response, but actually it does not forward any data packets or only sends part of the data.…”

Cross Layer Secure and Resource-Aware On-Demand Routing Protocol for Hybrid Wireless Mesh Networks

“…A secure intra-mesh routing protocol (SIMRP) [18] is resistant to fabrication, replay and most of the common security attacks, but it is unable to respond to collaborative, blackhole, grayhole and wormhole attacks. JANUS [8] is a framework for secure routing in WLANs and cellular networks, which are single-hop in nature, so this mechanism may not perform well in a multi-hop wireless networks.…”
