Data-on-the-Road in Intelligent Transportation Systems Ouri Wolfson and Bo Xu Department of Computer Science University of Illinois at Chicago Chicago, IL 60532, USA {wolfson,boxu}@ explore a new paradigm that is based on peer-to-peer Abstract - In this paper we examine the dissemination of communications. information about resources in mobile ad-hoc networks, where moving objects communicate with each other via We assume that each moving object (i.e. vehicle) has the short-range wireless transmission. Each disseminated capability of communicating with its neighbors. This resource represents an observed spatial-temporal event, communication can be enabled by a local area wireless and the relevance of the resource to a moving object protocol such as IEEE 802.11 [6], Ultra Wide Band decays as the age of the resource and the distance from (UWB) [9], Bluetooth [7], or CALM [8]. These protocols its location increase.
