Abstract
Based on observations gained from the previous chapters, an adaptive MAC protocol called Ada-MAC is presented in this chapter, which is built on top of IEEE 802.15.4 to achieve reliability, real-time transmission, adaptivity, and collision avoidance. The protocol consists of a series of efficient mechanisms such as the time-triggered mechanism, the priority queue mechanism, and the adaptive mini-slot allocation strategy. Ada-MAC not only assigns dynamic GTS but also supports differentiated services for end nodes. Real-time and reliable transmission is guaranteed for nodes with high priority, while data transmission of nodes with low priority is accommodated in unassigned time slots. The performance of Ada-MAC is evaluated via extensive simulations. The results are discussed in detail with a summary at the end of the chapter.
