Abstract
IEEE 802.11p-based wireless access in vehicular
environments (WAVE) multi-channel communication introduces
communication clusters which limits on the dissemination
efficiency of broadcast applications such as safety messaging. This
paper proposes cooperative multi-channel information
dissemination (CMD) which follows a channel coordination
approach where the coordinator is selected based on the least
average distance (LAD) to all service channels with the goal of
relaying the emergency message to other service channels with
minimum delay. On receipt of high priority emergency messages,
each selected channel coordinators switches to a defined service
channel and broadcasts the emergency message to it members. In
the CMD approach, each vehicle assumes a single radio and the
number of channel coordinators in each service channel cluster is
determined based on the available service channels advertised
and LAD to the advertised service channels. Computer
simulations show that the proposed CMD performs well in terms
of dissemination delay and dissemination rate.
