Abstract

Abstract:

To solve the problem of channel resource wasted by exposed terminals in mobile Ad hoc network, exposed terminals is researched. It is pointed out that the key problem is local network topology. Then a concurrent transmission algorithm based on local topology is proposed. In this algorithm, exposed terminals determines whether conflict happens in concurrent transmission through local network topology and complete concurret transmission by synchronization algorithm. Combined with IEEE 802.11 DCF protocol and cross layer mechanisms, a new protocol local topology based distributed coordination function(LTB_DCF) is developed. Simulation results show that compared with DCF, LTB_-DCF protocol improves the network throughput greatly with moderately low overhead.

Key words: mobile Ad hoc network, local topology, exposed terminals, concurrent transmission
