Agent based Dynamic Analytical Hierarchy Routing Protocol for Vehicular Ad hoc Networks

Vehicular Ad hoc Networks (VANETs) has a large research potential due to the requirement of real-time traffic information and its various applications. QoS requirements are important for VANET applications to ensure safety and provide emergency services. Due to the highly dynamic environment the connectivity between vehicles degrades leading to a highly unstable network. Existing algorithms does not guarantee the stability in network during the routing process. They ignore the mobility constraints which are the most influential factors in VANETs. Routing in VANETs can be modeled as a multi-criteria decision making problem. To address the problem of stability by ensuring high throughput and packet delivery ratio with reduced delay, a routing protocol has been designed and implemented using agent based analytical hierarchy process. Experimental results show a significant improvement in achieving the network stability compared to traditional algorithms.
