【摘要】：在無(wú)線Mesh網(wǎng)絡(luò)中,絕大部分?jǐn)?shù)據(jù)都是通過(guò)網(wǎng)關(guān)與外網(wǎng)進(jìn)行交互,隨著網(wǎng)絡(luò)中數(shù)據(jù)傳輸量的增加,單網(wǎng)關(guān)很容易達(dá)到傳輸瓶頸,從而導(dǎo)致網(wǎng)絡(luò)的整體性能下降.本文對(duì)802.11s中規(guī)定的混合無(wú)線Mesh路由協(xié)議HWMP(Hybrid Wireless Mesh Protocol)進(jìn)行改進(jìn),提出了具有負(fù)載均衡功能的多網(wǎng)關(guān)路由協(xié)議LBM P_HWM P.通過(guò)在M esh管理幀中添加路徑負(fù)載信息位,用于表示當(dāng)前路徑的節(jié)點(diǎn)擁塞情況,節(jié)點(diǎn)在選擇網(wǎng)關(guān)傳輸數(shù)據(jù)的時(shí)候綜合考慮鏈路質(zhì)量與路徑中節(jié)點(diǎn)的擁塞情況,從而均衡整個(gè)網(wǎng)絡(luò)的負(fù)載,避免擁塞發(fā)生.仿真實(shí)驗(yàn)表明,LBMP_HWMP能夠很好地保持整個(gè)網(wǎng)絡(luò)的負(fù)載均衡,降低端到端的傳輸時(shí)延,提高網(wǎng)絡(luò)的整體性能.
[Abstract]:In the wireless Mesh network, most of the data are interacted with the external network through the gateway. With the increase of data transmission in the network, the single gateway can easily achieve the bottleneck of transmission, resulting in the overall performance degradation of the network. In this paper, the mixed wireless Mesh road defined in 802.11s is changed by the protocol HWMP (Hybrid Wireless Mesh Protocol). In addition, the multi gateway routing protocol LBM P_HWM P. with load balancing function is proposed to express the node congestion in the current path by adding path load information bits in the M ESH management frame, and the node considers the link quality and the congestion in the path when the data is transmitted by the gateway, thus balancing the entire network. The simulation experiment shows that LBMP_HWMP can maintain the load balance of the whole network well, reduce the end to end transmission delay, and improve the overall performance of the network.
