research hotspots

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 chi hair straightener adopted TDMA (Time Division Media Access) protocol. One effective method of improving TDMA protocol is to adopt STDMA (Spatial TDMA) mechanism. So lastly chi flat iron combining the ascendants both of them, STDMA MAC protocol, linking scheduling and Ad Hoc networking method are proposed.This dissertation starts with the basic conceptions chi flat iron and characteristics of ultrashort Selforganized Network and introduces the current main problems and application foreground of men's nike shoes wireless Selforganized Network. Later some advantages of the directional antenna as many aspects are described which including Spatial division multiple access, the antenna gain, anti-interference chi hair straighteners etc. After that the possibility about the directional antenna used for the ad hoc networks is Lacoste Polo Shirts analyzed. Secondly Ad Hoc network multiple access protocols including STDMA protocol are studied, at the same time comparing with the protocol differences and network performance between isotropic and directional antenna in particular environment.
