【摘要】：無線體域網(wǎng)絡比傳統(tǒng)傳感網(wǎng)絡要求更高的數(shù)據(jù)傳輸可靠性和及時性,其可靠性屬于數(shù)據(jù)包級可靠。提出了一種及時可靠的無線體域網(wǎng)絡傳輸協(xié)議AODV-RT,該協(xié)議考慮到節(jié)點的存儲資源受限和無線體域網(wǎng)絡數(shù)據(jù)優(yōu)先級,采用E2E(EndTo-End)、HBH(Hop-By-Hop)以及E2E與HBH相結合的錯誤恢復機制保證數(shù)據(jù)傳輸?shù)目煽啃浴Ｊ紫仍诿總�節(jié)點緩存優(yōu)先級別最高的警報信息,提供HBH錯誤恢復;其次通過在中間節(jié)點位置為接收信號強度RSSI較低的后一級節(jié)點緩存優(yōu)先級別較高的數(shù)據(jù)包,提供E2E與HBH相結合的錯誤恢復;最后對低優(yōu)先級數(shù)據(jù)采取E2E錯誤恢復。性能分析與模擬實驗表明:該協(xié)議在數(shù)據(jù)傳輸率、端到端延遲和能量消耗等方面優(yōu)于相似協(xié)議MAODV-SIM。
[Abstract]:Wireless bulk area network requires higher reliability and timeliness of data transmission than traditional sensor network, and its reliability belongs to packet-level reliability. This paper presents a timely and reliable wireless bulk area network transport protocol AODV-RT.The protocol takes into account the limited storage resources of nodes and the priority of wireless body area network data. The reliability of data transmission is ensured by using the error recovery mechanism of E2E EndTo-EndTo-EndPen (HBH- Hop-By-Hopp) and E2E combined with HBH. First, the alert information with the highest priority level is cached at each node to provide HBH error recovery; secondly, the higher-priority data packets are cached at the intermediate node location for the lower level of received signal strength RSSI. Provide E2E combined with HBH error recovery; finally take E2E error recovery for low priority data. Performance analysis and simulation experiments show that the proposed protocol is superior to MAODV-Simm in data transmission rate, end-to-end delay and energy consumption.
