The prevalence of Wi-Fi hot spots in cities has formed the backbone of a converged wireless platform for mobile users. The need for location-based advertising, reducing the cost of advertisement, and higher transfer speeds, has fuelled the birth of ad hoc incentive-based advertising. In this article, we propose an advertisement protocol that employs policy management to control the propagation of messages within a given mobile region using IEEE802.11. With this approach, the mobile user forwards the message (which is bandwidth intensive) to another mobile user via IEEE802.11, who may be rewarded for forwarding it. Nevertheless, the minimal bandwidth activities such as security, propagation co-ordination and accounting, are managed by the licensed mobile network operator. The proposed framework benefits both the advertiser and the end users.
