“…OLSR-EA is able to prolong network lifetime and save total energy in MANET scenarios with a variety of traffic loads, node mobilities, and both homogeneous and heterogeneous power consumptions among the nodes. Cervera et al [35] presented taxonomy of flooding disruption attacks that affect the topology map acquisition process in Hierarchical OLSR (HOLSR) network, and preventive mechanisms to mitigate the effect of this kind of attack. According to their work, it is possible to mitigate the effect of flooding disruption attack by selecting MPR set with additional coverage or generating control traffic with redundant information.…”

Abstract-Characteristics of the mobile ad-hoc networks such as nodes high mobility and limited energy are regarded as the routing challenges in these networks. OLSR protocol is one of the routing protocols in mobile ad hoc network that selects the shortest route between source and destination through Dijkstra's algorithm. However, OLSR suffers from a major problem. It does not consider parameters such as nodes' energy level and links length in its route processing. This paper employs the artificial immune system (AIS) to enhance efficiency of OLSR routing protocol. The proposed algorithm, called AIS-OLSR, considers hop count, remaining energy in the intermediate nodes, and distance among node, which is realized by negative selection and ClonalG algorithms of AIS. Widespread packet -level simulation in ns-2 environment, shows that AIS-OLSR outperforms OLSR and EA-OLSR in terms of packet delivery ratio, throughput, end-end delay and lifetime.

“…As a consequence, the nodes in the network compute inconsistent routing tables that do not reflect accurately the network topology. In link state routing protocols for MANETs, some attacks can be launched even in networks with either cryptographic capabilities [24,32,31] or Intrusion Detection Systems (EDS) [65,21,46] implemented, e.g., a misbehaving node refuses to compute a valid MPR set.…”

In link state routing networks, every node has to construct a topological map through the generation and exchange of routing information. Nevertheless, if a node misbehaves then the connectivity in the network is compromised. The proactive Optimized Link State Routing (OLSR) protocol has been designed exclusively for Mobile Ad Hoc Networks (MANETs). The core of the protocol is the selection of Multipoint Relays (MPRs) as an improved flooding mechanism for distributing link state information. This mechanism limits the size and number of control traffic messages. As for several other routing protocols for MANETs, OLSR does not include security measures in its original design. Besides, OLSR has been extended to address a number of problems in MANETs. For example, Hierarchical OLSR (HOLSR) has been proposed to address scalability and Multipath OLSR (MP-OLSR) to address fault tolerance. However, these OLSR extensions can be affected either by inheriting or adding new security threats. In this chapter, we present a review of security issues and countermeasures in link state routing protocols for MANETs.
