Data dissemination services embrace a wide
variety of telematic applications where data packets are generated at a remote
server in the Internet and destined to a group of nomadic users such as vehicle
passengers and pedestrians. The quality of a data dissemination service is
highly dependent on the availability of network infrastructures in terms of the
access points. In this article, we investigate the utilization of roadside
wireless local area networks (RS-WLANs) as a network infrastructure for data dissemination.
A two-level cooperative data dissemination approach is presented. With the
network-level cooperation, the resources in the RS-WLANs are used to facilitate
the data dissemination services for the nomadic users. The packet-level
cooperation is exploited to improve the packet transmission rate to a nomadic
user. Various techniques for the two levels of cooperation are discussed. A
case study is presented to evaluate the performance of the data dissemination
approach.
