Simulation is an important approach to evaluate protocols. Realistic simulations lead to accurate evaluations. However, most of evaluations in VANET recently were still using MAN.ET mobility models or MANET models with a map bounder. Existing VANET mobility models, which treat all nodes identical, cannot reach most researchers' demand. In this paper, we develop a role based mobility model for VANET...
Vehicular ad-hoc network (VANET) is surging in popularity, in which vehicles constitute the mobile nodes in the network. Due to the prohibitive cost of deploying and implementing such a system in real world, most research in VANET relies on simulations for evaluation. A key component for VANET simulations is a realistic vehicular mobility model that ensures that conclusions drawn from simulation experiments...
The main objective of vehicular ad hoc networks (VANETs) is reliable delivery of emergency warning messages so that drivers can make well-timed decisions and prevent mishaps. The dynamic vehicular environment in VANETs makes it necessary to examine its effects on the network to ensure that the messages reach the intended vehicles in its range, on time. The objective of this paper is to monitor the...
The distance between vehicles measurement is the only factor in traditional car rear-end alarm system. An alarming model based on MAS(Multi-Agent Systems) and driver's behavior is proposed to address the above problem. It is composed of four different types of agent, interface-agent, features-extraction-agent, recognition- agent and alarm-agent, which can either work alone or collaboration through...
