【摘要】：為事件驅(qū)動(dòng)的災(zāi)害監(jiān)測傳感網(wǎng)提出一種基于分簇和協(xié)作MIMO的節(jié)能數(shù)據(jù)傳輸方法C2 MIMO。首先,在網(wǎng)絡(luò)中構(gòu)造監(jiān)測簇和中繼簇,從簇中選出一個(gè)主簇頭和若干個(gè)從簇頭,它們充當(dāng)協(xié)作MIMO的協(xié)作發(fā)送節(jié)點(diǎn)和接收節(jié)點(diǎn)。隨后,利用協(xié)作傳遞的方法將數(shù)據(jù)從監(jiān)測簇逐簇傳遞,直到交付給Sink節(jié)點(diǎn)。從協(xié)作MIMO的能耗模型和仿真實(shí)驗(yàn)的結(jié)果可知,C2 MIMO能夠較好地適應(yīng)長距離的中繼傳輸,并對(duì)信道惡化具有較強(qiáng)的忍耐能力。
[Abstract]:A Energy-saving data Transmission method C _ 2 MIMO. based on clustering and Cooperative MIMO for event driven disaster Monitoring Sensor Network First, monitor and relay clusters are constructed in the network, and a main cluster head and several slave cluster heads are selected from the cluster, which act as cooperative sending and receiving nodes of cooperative MIMO. Then, the data is transferred from the monitoring cluster to the Sink node by the cooperative transfer method. From the energy consumption model of cooperative MIMO and the results of simulation experiments, it can be seen that C2 MIMO can adapt to long distance relay transmission and has strong endurance to channel deterioration.
