Intrusion tolerant QoS provision in mobile multihop relay networks

Abstract

We propose in this article an architecture called trusted timely attacks-tolerating communication architecture (3TCA) designed for mobile multihop relay (MMR) networks. The 3TCA architecture is based on trusted components providing trusted time-related and security-related services along with an intrusion-related service while guaranteeing QoS compensation. 3TCA components are implemented at access nodes such as relay stations (RSs) and multihop relay base stations (MR-BSs) in order to achieve trusted QoS-aware handover management while guaranteeing intrusion tolerance. In particular, we provide QoS guarantees in terms of delay, bandwidth and jitter for the MMR networks while addressing group mobility through performing handover disturbance compensation for mobile RSs. Meanwhile, we tolerate particular timely-based and DoS attacks through compensating their impact on the already agreed QoS level. Simulations show that adopting compensation is suited for the MMR context although it induces additional complexity. © 2013 Krichene and Boudriga.
