【摘要】：提出了一種新的自適應(yīng)混合MAC協(xié)議TC2-MAC。該協(xié)議采用了基于二叉樹(shù)結(jié)構(gòu)的時(shí)隙塊分配策略和基于時(shí)隙約束的CSMA/CA競(jìng)爭(zhēng)接入方式,能夠?yàn)椴煌瑐鞲衅鞴?jié)點(diǎn)或不同類型業(yè)務(wù)的差異性QoS需求提供良好支持,并能夠通過(guò)靈活的信息調(diào)度機(jī)制改善信道接入公平性,提高網(wǎng)絡(luò)效率。理論分析和仿真結(jié)果表明:與傳統(tǒng)基于TDMA機(jī)制的MAC協(xié)議相比,TC2-MAC對(duì)網(wǎng)絡(luò)業(yè)務(wù)流量及拓?fù)浣Y(jié)構(gòu)的變化均具有更好的自適應(yīng)性。
[Abstract]:A new adaptive hybrid MAC protocol TC2-MAC is proposed. The protocol adopts slot block allocation strategy based on binary tree structure and CSMA / CA competitive access mode based on slot constraints, which can provide good support for the different QoS requirements of different sensor nodes or different types of services. It can improve channel access fairness and network efficiency by flexible information scheduling mechanism. Theoretical analysis and simulation results show that: compared with the traditional MAC protocol based on TDMA mechanism, TC2-MAC has better adaptability to network traffic and topology changes.
