通信中繼站
英文
communication relay station-
An artificial satellite which is projected into a predetermined orbit around the earth to function as a relay station
一種發射到預定軌道的人造地球衛星,它的功能相當於一個通信中繼站。With the rapid development of wireless communication technology and computer technology , people wish to get reliable data communication service any time and any where. traditional network can not supply communication service if the whole network need to move because the network devices are fixed by wires and can not move. so, ad hoc network comes. it can provide mobile data communication service compared with traditional network. ad hoc is a network with plat structure and all the nodes is equal. all the nodes need provide relay. but not all the nodes will provide relay and the performance of plat structure is poor in large scale. so the wireless mobile self - organized network adopts a two - level structure by referencing the cell mobile communication system. wmsn uses wireless routers to construct network. it can provide wireless access, relay services to users
考慮到不是所有的站點都願意提供中繼服務及平面結構的局限性(在網路規模較大時性能會很差) ,本課題的無線移動自組織網路參考了蜂窩移動通信系統的特點,是一種具有兩級結構的網路。使用專門的無線設備? ? 「無線路由器」構成具有用戶無線接入、無線組網和路由功能的無線互連網路,為移動用戶提供無線接入、路由和中繼服務。 ieee802 . 11b可以提供很高的通信速率,可以提供很好的接入性能,並且支持ieee802 . 11b協議的設備正成普及的態勢,因此成為我們所選擇的鏈路層協議。At present, el interface based on g703 is widely applied group network, relay network, gsm mobile base station and military communication for the purpose to transmit voice signals, data, pictures and etc. in this paper, the author firstly analyses the developing tendency and status quo of nowadays digital loop system
