摘要：In this paper a new algorithm for the selection of multipoint relays (MPR) in optimized link state routing protocol (OLSR) is proposed. OLSR is a routing protocol which could reduce the overhead of control messages by selecting MPRs. So, the number of MPRs is a key for the performance of OLSR. However, as the greedy algorithm introduced in RFC 3626 has some problems with MPR selection, which will make a negative effect on the security performance of OLSR. In fact, the OLSR is known to be vulnerable to various kinds of malicious attacks. This paper proposes a collusion attack against MANETs exploiting vulnerabilities of OLSR. In this attack, two attacking nodes cooperate in order to disrupt the topology discovery and prevent routes to a target node from being established in the network.
