Cognitive security protocol for sensor based VANET using swarm intelligence
Rajani Muraleedharan, Lisa Ann Osadciw · 2009
Intelligent Transportation system (ITS) using wireless and mobile ad-hoc sensor network has inspired many autonomous applications. Vehicular Ad-hoc network (VANET) is an emerging technology where vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communicate wirelessly using dedicated short-range communication band. In sensor based VANET (S-VANET) issues like response time, data aging, bandwidth, packet delivery, message prioritization and communication cost is a major concern. In this paper, we apply cognitive security protocol that disseminates information using distributed sensor technology while prioritizing prevention of data aging, efficient quality-of-service (QoS) and robustness against denial-of-service (DoS) attack. The reliability and optimality of the protocol is computed based on current mission response time and maintaining message authentication, integrity, confidentiality and non-repudiation.
