Experimental Evaluation of Location-Based Mobile Agent Migration Mechanism for Information Dissemination Scheme in VANETs

A vehicular ad hoc network (VANET) consists of vehicles (mobile nodes) and road side units which are equipped with the wireless devices such as wireless LANs. As one of the application scenarios (use case) in VANETs, there is the information provision of the parking spaces´ situation in the city central to vehicles (mobile nodes). In this scenario, the road side unit (source node) deployed at the parking spaces periodically disseminates the empty information to mobile nodes in VANETs. Therefore, we have proposed a location-based mobile agent migration mechanism which decides how to migrate mobile agents in the network for information dissemination scheme in VANETs. In this paper, we conduct the simulation experiments in the VANET environment to evaluate the proposed information dissemination scheme, and then show the effectiveness in comparison with Epidemic routing.
