摘要：The optimized Time Division Multiple Access (TDMA) schedules can achieve high power efficiency,zero conflict, and reduced end-to-end delay. Based on the network-wide flow distribution, the energy is calculated.Based on the optimization model and transmission power on every link, we then propose an algorithm for deriving theTDMA schedules, utilizing the slot reuse concept to achieve minimum TDMA frame length. We present a new MACprotocol, which is referred to as Hybrid MAC (HMAC), which is suitable for WSNs in terms of energy efficiency,latency, and design complexity. HMAC combines channel-allocation schemes from existing contention-based andtime-division multiple-access (TDMA) based MAC protocols to allow the understanding of tradeoffs between differentperformance metrics. Our future protocol (HMAC) combines energy-efficient features of the existing contention-basedand time-division multiple access (TDMA)-based MAC protocols and adopts a short frame structure to speed up packetdelivery. HMAC provides routing technique for coarse-grained quality-of-service (QoS) support at the MAC layer. Inthis project, we are going to implement an analysis of slot reuse with non-negligible interference and fixed framelength.
