RSU message updating and broadcasting using TLB algorithms with secure navigation in VANET

Abstract

VANET (Vehicular Ad hoc Networks) is one of the dynamic domains to enhance the research issues. VANETs regard vehicles are considered as mobile nodes and give the way for driving securely by conveying information between vehicles. In VANET, the vehicles are consider as mobile nodes should have been designed with an On Board Unit (OBU) and on the road (stationary) there are Road Side Units (RSUs-Infrastructure Based) embedded. In general there are two ways of communications are taken places in VANET: One is between the vehicles of data propagation from source node to destination node were both nodes are in mobile. The second way of communication is through RSU i.e. the RSU is importunate the data transfer to the vehicles. Here either source or destination node is mobile the RSU is immobile; Vehicle-to-RSU communication (V2R.). Often the links disconnects due to high mobility of the vehicles hence the communication path needs to be modify and reestablish very frequently. As a result to provide routing protocols in VANET is become bottleneck with low delay and low overhead. By considering the issue we proposed TLB (Teacher-Learner based) optimization algorithm through which updating the routing information in RSU recurrently and broadcasting the information among the mobile node. Here RSU consider as teacher phase and vehicles consider as learner phase. TLB algorithm replicate the consequence of teacher’s influence on the output of learners in a class also it is a population based algorithm.
