A Novel Directional Ad Hoc MAC

Abstract

Recently, Ad Hoc network is adapted widely in military, agriculture, and disaster rescue owing to the character flexible and fast deployment without infrastructure itself. However, the omnidirectional Ad Hoc cannot fulfill the requirements from people of increasing the capacity and the bandwidth of network caused by drastic explosion of information. By contrast, the directional antenna is more advantage than the omnidirectional one, which have the capability to improve the performance of Ad Hoc including more transmission range, less interference, spatial reuse, more capacity and tactical silence. Based on the existing lecture, a novel directional MAC found on STDMA（Spatial Time Division Multiple Access）is raised and provide high throughput, high transmission rate and low delay to network system which contribute to share massive information and improve the performance of the network.
