Description:	A Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a temporary network without using any existing network infrastructure or centralized administration. OLSR routing protocol it will be vulnerable to malicious nodes as black hole attack. Black hole attack involved in MANET were based on proactive routing protocol OLSR routing protocol, OLSR is a security problem emanating from attacks. When forwarding packet to destination, several types of confidentiality, authentication and integrity caused by the attack. This research utilizes the Secure Open Link State Routing (SOLS) mechanism which includes certificate authorized nodes (CAs) and Relatively Slow Algorithm (RSA) to enhance the security and provide secure routing for OLSR routing protocol, through detection of malicious nodes that perform black hole attack. The proposed protocol is called Securing Optimized Link State Routing Protocol (SOLS) mechanism. The aim of using the RSA algorithm with certificate authorized nodes (CAs) is to find the secure path from the source to the destination and to detect the black hole attack. We have evaluated the performance of (SOLS) mechanism by designing simulation using MATLAB. We have compared our mechanism with the performance of protocol OLSR and Baadachi’s approach. The comparison was conducted based on the detection ratio, packet delivery ratio, routing overhead, total network load, average delay and source traffic sent & destination traffic received. The (SOLS) outperformed the Baadachi’s approach under wide network performance metrics and settings. The SOLS improved the detection ratio by 4% compared to Baadachi’s approach; the implication of this finding is that (SOLS) can be applied in MANET to detect black hole attack.,Master of Computer Science
