Abstract

Using directional antennas in wireless mobile ad hoc networks can greatly improve the transmission range as well as the spatial reuse However it will also cause some problems such as deafness problem and hidden terminal problem which greatly impair the network performance This paper first proposes a MAC protocol called Selectively Directional MAC SDMAC that can effectively address these problems and significantly improve the network throughput Then two improvements on SDMAC are proposed The first one is to improve the network throughput by scheduling the packets in the queue a scheme called QSDMAC thus the headofline HOL blocking problem can be addressed The second one is to relax the assumption that each node knows the relative directions of its neighboring nodes and use caches to buffer those relative directions a scheme named QSDMAC using cache Extensive simulations show that 1 SDMAC can achieve much better performance than the existing MAC protocols using directional antennas 2 The network throughput can be significantly improved by scheduling the packets in the queue 3 Using caches can still achieve high network throughput when nodes are moving and 4 Network throughput decreases when directional antennas have side lobe gainThe work of Li Zhai and Fang was supported in␣part by US National Science Foundation NSF under Grant CNS0721744 and GrantDBI0529012 The work of Fang was also supported in part by the National Science Council NSC ROC under the NSC VisitingProfessorship with contract number NSC962811E002010
