Abstract :
Polling as one kind of the TDMA medium access control protocols has the advantage of energy conservation, however, its extensibility is not as good as that of contention-based protocol. The controllable threshold polling medium access protocol (CTP-MAC) in this paper is designed to realize the self-organizing in slot assignment and synchronization. Methods of the imbedded Markov-chain theory and the probability generating function are used to propose an analysis model of energy efficient for wireless sensor network. Mathematic analyses are compared with the simulations results.
