【摘要】：水下聲波的傳播時(shí)延及波動(dòng)遠(yuǎn)大于無線電波,許多借鑒陸地?zé)o線電波通信網(wǎng)絡(luò)原理設(shè)計(jì)的水聲傳感器網(wǎng)絡(luò)協(xié)議未能充分考慮和利用水聲傳播及其時(shí)延變化特性.據(jù)此給出了時(shí)分多址協(xié)議中相繼傳輸數(shù)據(jù)包的沖突模型,分析了保護(hù)間隔與簇頭節(jié)點(diǎn)和傳感器節(jié)點(diǎn)距離之間的關(guān)系,并給出了保護(hù)間隔的設(shè)置方法.理論分析和仿真表明,提出的保護(hù)間隔設(shè)定方法改善了傳統(tǒng)保護(hù)間隔設(shè)置偏向保守的缺點(diǎn),可有效提升水聲傳感器網(wǎng)絡(luò)的性能和效率.
[Abstract]:The propagation delay and the fluctuation of underwater acoustic waves than radio waves, radio waves from many terrestrial communication network protocol design principle of underwater acoustic sensor networks do not consider and use of acoustic propagation and time delay. The variation characteristics of given TDMA protocol in successive transmission packet conflict model, analyzes the relationship between the guard interval and cluster the distance between the head and the sensor nodes, and gives the method of setting the protection interval. Theoretical analysis and simulations show that the proposed method set the interval protection improves the traditional protection interval setting bias conservative shortcomings, can effectively improve the performance and efficiency of the underwater acoustic sensor networks.

【正文快照】： 水聲傳感器網(wǎng)絡(luò)(UWSN)在海洋生態(tài)環(huán)境監(jiān)測(cè)、離岸勘探、災(zāi)難預(yù)防、輔助導(dǎo)航等領(lǐng)域應(yīng)用廣泛,社會(huì)效益和潛在戰(zhàn)略應(yīng)用價(jià)值巨大.與陸地?zé)o線傳感器網(wǎng)絡(luò)顯著不同的是,水下節(jié)點(diǎn)采用水聲通信方式,水下聲信道具有許多與無線電信道不同的特性[1-3],如傳播時(shí)延長(zhǎng)、信道帶寬低、信道錯(cuò)誤率，
