本文提出了一種新的無(wú)線微傳感器網(wǎng)絡(luò)協(xié)議和組織結(jié)構(gòu)ALEP。與傳統(tǒng)的無(wú)線微傳感器網(wǎng)
絡(luò)協(xié)議相比,ALEP 更加充分地考慮到實(shí)際應(yīng)用,將一種高效能量控制算法引入組網(wǎng)協(xié)議,提高了網(wǎng)絡(luò)的能量利用率,顯著延長(zhǎng)了無(wú)線網(wǎng)絡(luò)的生命周期,增強(qiáng)了網(wǎng)絡(luò)的健壯性。通過(guò)對(duì)ALEP 協(xié)議進(jìn)行OPNET仿真,結(jié)果顯示該協(xié)議與傳統(tǒng)模式的無(wú)線微傳感器網(wǎng)絡(luò)協(xié)議相比,在傳送相同的數(shù)據(jù)量的條件下有更高效的能量特性和信息傳輸特性。

Abstract :An energy - optinization - based and self - adaptive protocol for wireless microsensor network is pre2 sented in this paper. Compared to traditional wireless micorsensor network protocols , this protocol fully utilizes an energy - optimization control architecture to prolong the life of the wireless microsensor network ,and to im2 prove the robust of network. Simulation result shows that the proposed protocol makes more effective energy uti2 lization and has better transmission characteristics.
