Abstract: Vehicular ad hoc networks (VANETs) unfold the possibilities for a large number of applications. An attractive application is the advertisement of roadside services. Current solutions for the provision of roadside services make use of private cars. However, it would not be possible for the business owners to give incentives to all participating car owners. We proposed a novel protocol for roadside services advertisement using public buses. The road side unit (RSU) broadcast the services to the buses, which store them for a predefined time. We evaluate the performance of our proposed solution in a multi-lane highway scenario. We also compared the performance of our protocol with existing solution under various traffic conditions. The results of our experiments revealed that: (a) broadcast frequency and speed of the buses influenced the advertisement messages received by the buses; (b) by using a broadcast frequency of 5/s, the buses were able to receive all the advertised services.
