A Mobile Agent Migration Mechanism for Information Dissemination Scheme in VANETs Considering Entrance and Exit of Mobile Nodes

摘要

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. Mobile nodes exchange the information messages with each other so that VANETs are configured in a self-organized manner. As one of the application scenarios (use case) in VANETs, there is the information provision of the parking lots' situation in the city central to vehicles (mobile nodes). In this scenario, the road side unit (source node) deployed at the parking lot periodically disseminates the empty information to mobile nodes in VANETs. Therefore, we have proposed a mobile agent-based information dissemination scheme in the VANET environment. In this paper, we propose a location-based mobile agent migration mechanism which decides how to migrate mobile agents in the network. In addition, we conduct the simulation experiments in the VANET environment considering the entrance and exit of mobile nodes to evaluate the proposed information dissemination scheme.
