— This work proposes an enhancement of the GPSR routing protocol to improve the performance of point-to-point IP-based voice communications in a vehicular ad-hoc network. Our enhancement reduces significantly the end-to-end delay in ad-hoc networks using a TDMA-based Medium Access Control protocol. The proposed enhancement of GPSR routing basically consists(More)
IP telephony over mobile ad hoc networks is a topic of emerging interest in the research arena as one of the paths toward the fixed-mobile convergence in telecommunications networks. To investigate the performance characteristics of this service, we propose a complete system architecture, which includes a MAC protocol, a routing protocol, and the treatment(More)
