1、無線網(wǎng)狀網(wǎng)的研究與探討無線網(wǎng)狀網(wǎng)的研究與探討無線網(wǎng)狀網(wǎng)的研究與探討摘要：無線網(wǎng)狀網(wǎng)由網(wǎng)格路由器和網(wǎng)格客戶端組成，其中網(wǎng)狀路由器具有最小可移動性，形成了無線網(wǎng)狀網(wǎng)的骨干，它們同時為網(wǎng)狀客戶端和普通客戶端提供網(wǎng)絡(luò)訪問。通過網(wǎng)狀路由器的網(wǎng)關(guān)和橋接的功能，無線網(wǎng)狀網(wǎng)能同其它的無線網(wǎng)比如Inter蜂窩網(wǎng)，無線局域網(wǎng)，傳感網(wǎng)絡(luò)等互聯(lián)。無線網(wǎng)狀網(wǎng)被期望用來解決adhoc網(wǎng)絡(luò)，無線局域網(wǎng)及無線城域網(wǎng)的局限性和大量的提高它們的效率，這些網(wǎng)絡(luò)經(jīng)歷了快速的進
