STDMA protocol

How to design and optimize link layer protocols is one of the research hotspots in Mobile Ad Hoc networks. Firstly the link layer based on Scheduling strategies generally adopted TDMA (Time Division Media Access) protocol. One effective method of improving TDMA protocol is to adopt STDMA (Spatial TDMA) mechanism. So lastly combining the ascendants both of ugg boots 2010 them, STDMA MAC protocol, linking scheduling and Ad Hoc networking method are proposed.This dissertation starts with the basic conceptions and characteristics of ultrashort best clothes blog Selforganized Network and introduces the current main problems and application foreground of wireless Selforganized Network. Later some advantages of the directional antenna as many aspects are wedding dresses form china described which including Spatial division multiple access, the antenna gain, anti-interference etc. After that the possibility about the directional antenna used for the ad hoc networks is analyzed. Secondly Ad Hoc wedding dresses 2nd network multiple access protocols including dresses 1std protocol are studied, at the same time comparing with the protocol differences and online shoes store network performance between isotropic and directional antenna in particular environment.
