Abstract:
Vehicular Ad hoc Networks (VANETs) support a large number of Intelligent Transportation System (ITS) applications, ranging from safety to non-safety purposes. Non- safety applications encompass comfort, infotainment and marketing of services. In order to promote business, alongside roads and highways, and reach to maximum number of customers, the Business Managers (for instance: gas stations, restaurants, hotels, parking lots, coffee shops, supermarkets, etc.) would need a mechanism to advertise their services using a third party broker. Moreover, travellers (drivers, passengers) would need an efficient and cost effective way to discover these services, during their trips. However, the unique characteristics of VANETs (e.g., dynamic topology, high speed and densities, short inter-contact time, etc.) make the deployment of such applications a challenging task. This paper describes the use of the Opportunistic Service Discovery Protocol (OSDP) –a beaconing based protocol for roadside services discovery. We performed extensive simulation experiments to evaluate the performance of different phases of OSDP, under different traffic densities. The results concluded that: a) the number of advertisement packets, in a given region by different Road Side Units (RSUs), effect the success rate of receptions by moving vehicles; b) short inter-contact times (of around 1s) seem to be sufficient for a fast moving vehicle on a highway to receive at- least 70% of the advertisement packets from RSUs; c) the success rate of receiving response packets is highly affected by the density of neighbour vehicles; d) the model suggests that the system can be used to simulate several business models, including a number of advertisement points, their distances to the business's premises and duration that the packets are stored in the cache, etc.
