State of the Art in Simulation Software for Health Monitoring through Vehicular Ad-Hoc Network

Communication Technology has made considerable progress which was previously wired, now it has been wireless. In today's time, in every country, roads of every city are full of vehicles. Traffic jam problems are everywhere. Lack of road travel safety has imposed a threat to human lives and our environment as well. Providing road safety is becoming a serious challenge. A vehicular ad-hoc network is an important application of wireless technology that has attracted the attention of academicians and researchers. Intelligent Transportation System (ITS) cannot be conceived without Vehicular ad-hoc networks. VANETs provide the safety on the highway network by sharing beacons which contains vehicles information like direction, position and its speed. VANETs can provide warning messages to driver about risky situations such as traffic jams, accidents, road conditions. Traffic signal violation, Blind spot warning, Pedestrian crossing information, Lane change warning, Forward collision warning, Curve speed, Wrong way and Emergency vehicle service are some of the useful safety application of VANETs. Even more VANETs can provide Travelling Comfort services like automatic toll collection, information about roadside restaurant or parking zone, downloading routing map and movies, playing games and sending driver's physical health information via wireless body sensor network (WBSN) to nearby ambulance or hospitals. Making, deploying and testing of VANET on real ground for experimental purpose requires lot of budgets and efforts. Therefore simulation is preferred a good alternative before to actual execution. Academicians and Researchers have developed many VANET simulators to study and examine various kinds of emergency warning, data dissemination and routing protocols. When simulating VANETs we should consider specials characteristics of VANETs VANETs simulation requires different approaches than Mobile Ad-hocnetworks (MANET's) simulations because of drivers' behavior, unstable vehicular speed and mobility, restricted vehicular movements, multi-path fading, traffic lights and traffic congestion. Therefore VANETs requires traffic flow simulator and network simulator both for better and close to reality as possible results. Many traffic flow simulator and network simulator are now available easily but because of compatibility issues some of them have integration problem. Currently there are VANET simulators that provide GUI in which traffic flow simulator and network simulator can be integrated. In this paper authors presents licenses based and open accessed traffic flow simulator, network simulator and VANETs simulators.
