Abstract

Unique advantages of directional antennas have attracted much interest of the researchers, such as longer transmission distance, large transmission antenna gains and large spatial reuse gains. However, the feature of directional transmission and reception (DTR) also brings challenges to the media access control (MAC) protocols, which means the nodes can only sense the wireless channel in a given direction and thus the interference or collision between the concurrent transmission links is difficult to be avoided. To address this problem, in this paper a novel collision scattering method is proposed to decrease the collision probabilities of the concurrent transmission links. The basic idea is to distribute the concurrent transmission links to different channels, which are divided in the wireless spectrum, such that multiple transmission links can be ongoing concurrently. A time division multiple access (TDMA) based multichannel MAC protocol is proposed based on the collision scattering method. Extensive simulations are carried out to evaluate the performance of the proposed protocol and the gain of the collision scattering. The simulation results show that the aggregation throughput of the proposed protocol outperforms the existing protocols and the collision scattering gain is achieved.
