摘要

摘要: 為改善無(wú)線體域網(wǎng)的能效和傳輸可靠性，該文針對(duì)其具有資源有限、信道質(zhì)量波動(dòng)頻繁、所傳輸數(shù)據(jù)有異構(gòu)性等特點(diǎn)，提出一種基于鏈路質(zhì)量預(yù)測(cè)的跨層優(yōu)化方案。通過對(duì)物理層、網(wǎng)絡(luò)層和MAC層的松散耦合，自適應(yīng)地選擇傳感器節(jié)點(diǎn)的傳輸功率，并且建立高效節(jié)能的端到端路由。仿真結(jié)果顯示，該方案相對(duì)于已有的單層協(xié)議，整體提高了體域網(wǎng)的能量效率和傳輸可靠性。

Abstract: In order to improve the energy efficiency and reliability of Wireless Body Area Networks (WBANs), this paper takes full consideration of characteristics of WBANs, such as limited resources, frequent channel quality fluctuations, heterogeneous data traffic, and proposes a Cross-Layer Optimization scheme based on link quality prediction (CLO algorithm). Through the loose coupling of physical layer, network layer and MAC layer, the transmission power of every sensor node is adaptively chosen, and the energy-efficient end-to-end routing is established. Simulation results show that the proposed scheme can improve the energy efficiency and transmission reliability of WBANs as compared with the existing single layer protocols.
