On a QoS Intrusion Tolerant Routing protocol in Ad-hoc Networks

Abstract

We propose in this paper a protocol, called QITAR, which will secure the ad-hoc routing process while guaranteeing end-to-end QoS requirements in terms of delay or bandwidth constraints. Our approach provides an intrusion tolerant environment and uses and enhances the concept of Trusted Timely Computing Base in order to deduce consistent delay information and verify the bandwidth value pretended by untrusted nodes. QITAR also proposes a rescue procedure that saves the resources and accelerates the route maintenance in case of node mobility. Intrusion tolerance, Ad-hoc Routing, QoS.

Intrusion tolerant QoS provision in mobile multihop relay networks

“…Speed sensitive HO scheme, [6] Speed sensitive HO under hierarchical cellular system Does not consider security issues Path selection method, [7] Secures the routing for MMR networks Does not consider QoS issues QITAR, [8] Achieves QoS and intrusion tolerance for ad hoc networks -Vulnerable to high-speed mobility-May experience scalability problems MERQIT, [9] Achieves QoS and intrusion tolerance for mesh networks -Clusterheads are mobile nodes that may experience attacks and leave the network-Isolates malicious nodes WSN-TUM, [13] Fault-intrusion tolerant framework for sensor networks -Split the packet on fragments and send them on disjoint routes. However MMR networks use the same route as the routing architecture is a tree rooted at the MR-BS-Global QoS is hard to guarantee since each fragment uses a different route with different QoS constraints-All sensors participate in the securization effort.…”

“…A few intrusion tolerant routing protocols for the ad hoc and mesh contexts have addressed QoS issues, [8,9]. However, such protocols can not be directly adopted by relay networks.…”

“…However, such protocols can not be directly adopted by relay networks. For instance, the QoS and intrusion tolerant ad hoc routing (QITAR) protocol that was proposed in [8] is a QoS aware intrusion tolerant routing protocol for ad hoc networks. Nevertheless, QITAR can not be applied in the MMR context as it is very vulnerable to high-speed mobility and it may experience scalability problems.…”
