AbstractThis paper suggests an information gathering and monitoring system designed for vehicular ad-hoc networks(VANETs) and that implemented in a large area.The suggested infrastructure consists of low cost wireless sensors covering certain areas and connected to “the monitoring and control center” through a master node, the study is divided into four phases: the first phase discusses the information gathering process in vehicles and sensors level, the second phase discusses how to send the brief road traffic information to the master node. This process is based on the concepts of the summarization and aggregation and study the effect of using one or two channels for that purpose, the third phase focuses on the information transportation between the master nodes until it reaches to “the monitoring and control center”, The mechanism of the information transportation in this phase is proposed to be in an ad-hoc manner using four ad-hoc protocols Ad-hoc On Demand Distance Vector Routing Protocol AODV,Dynamic Source routingDSR, Optimized Link State Routing Protocol OLSR and Temporally-Ordered Routing Algorithm Protocol TORA. The best protocol willbe selectedaccording to its data delivery, latency and average throughput on the radio channel and the fourth phase deals with dissemination of the gathered information to the vehicles.The proposed system is designed and simulated using “OPNET” package. The results indicate the ability of applying real time and high resolution monitoring system using these techniques.
