摘要：Mobile Ad Hoc Network (MANET) comprises a set of wireless mobile nodes which dynamically generate a temporary network devoid of application of any present network infrastructure and centralized administration. Basically, Optimized Link State Routing (OLSR) is a security problem emanating from attacks. When handling packet forwarding, several types of availability as well as integrity attacks exist, including fabrication, modification, misrouting and dropping whether full or partial. This research utilizes the Secure Optimized Link State Routing (OLSR mechanism which includes certificate authorized nodes (CAs) and RSA algorithm 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 (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 to MANET to detect black hole attack.
