In this paper we examine the dissemination of reports about resources in mobile peer-to-peer networks, where moving objects communicate with each other via short-range wireless transmission. Each disseminated report represents information about a spatial-temporal resource, such as the availability of a parking slot at a particular time and location. We introduce an architecture and a data model for dissemination of such reports. We develop an analytical model to quantify the benefit of report dissemination, where the benefit is measured in terms of time-saving. We further propose an incentive mechanism for participation in resource dissemination, and a method of pricing the resource information.¹
