An Evolutionary MAC Protocol based on FPRP for Decreasing Delay

Abstract

Five-Phase Reservation Protocol (FPRP) is a single channel, Time Division Multiplex Access (TDMA) based broadcast scheduling protocol for Ad Hoc network. A modified Medium Access Control (MAC) protocol based on FPRP for decreasing packet delay is proposed in this paper. In FPRP, There are quite a lot of reservation cycles in slots is not fully used, especially in latter slots, for the reason that the number of contention nodes decrease in latter slots. By modifying the frame structure of the Five Phase Reservation Protocol (FPRP), the time of slots assignment can be greatly decreased in the modification FPRP (MFPRP). The simulation results reveal that the reduction in reservation cycles doesn't affect the throughput in network obviously.
