Intrusion Tolerant Routing for Mesh Networks

Intrusion tolerant QoS provision in mobile multihop relay networks

“…Particularly, Figure 8 shows the processing delay according to the number of malicious nodes within a mesh network. We notice that the processing delay does not highly increase when a malicious clusterhead is only detected without being isolated, but that the same delay becomes very important when the number of malicious access nodes increases (i.e., for example when a router presents malicious entities and should broadcast its status to its neighbors or when a clusterhead should be completely isolated) [9].…”

“…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.…”

“…To achieve this, we propose to compare the simulation results obtained within the MMR networks context to those of an intrusion tolerant routing protocol within the mesh context. Such a routing protocol, called MERQIT, has been presented in [9]. We think that such a comparison is appropriate for two reasons.…”

“…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.…”

“…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. In order to address the mesh context, we proposed an Intrusion Tolerant routing protocol called mesh routing with QoS and intrusion tolerance (MERQIT) that guarantees consistent delay constraints while securing the route establishment procedure and achieving good performance at the metropolitan scale, [9]. MERQIT adopts the concept of clusterheads which are in charge of managing the non line of sight mobile nodes.…”
