【摘要】：針對傳統(tǒng)OLSR算法的傳輸功率消耗和節(jié)點剩余能量之間的矛盾,提出了一種基于組合優(yōu)化理論的能量感知路由算法(EW-OLSR).首先根據(jù)傳輸功率消耗和節(jié)點剩余能量構(gòu)建節(jié)點能量消耗數(shù)學(xué)模型,并將其作為路由選擇目標函數(shù),然后在節(jié)點剩余能量計算中引入ARIMA-LSSVM組合預(yù)測模型,最后根據(jù)能量消耗最小路徑選擇數(shù)據(jù)傳輸路由.實驗結(jié)果表明,EW-OLSR算法不僅減少了網(wǎng)絡(luò)能量消耗和傳輸時延,而且提高了分組到達率,在無線網(wǎng)絡(luò)中具有廣闊的應(yīng)用前景.
[Abstract]:An energy-aware routing algorithm (EW-OLSR) based on combinatorial optimization theory is proposed to solve the contradiction between transmission power consumption and node residual energy in traditional OLSR algorithm. Firstly, the mathematical model of node energy consumption is constructed according to the transmission power consumption and the residual energy of the node, which is regarded as the route selection objective function, and then the ARIMA-LSSVM combination prediction model is introduced into the calculation of the residual energy of the node. Finally, the data transmission route is selected according to the minimum energy consumption path. The experimental results show that the EW-OLSR algorithm not only reduces the network energy consumption and transmission delay, but also improves the packet arrival rate, so it has a broad application prospect in wireless networks.
