To improve performance of wireless sensor networks in terms of energy consumption,network latency and traffic adaption,this paper proposed LCT-MAC with collision avoidance and traffic adaption through analyzing some classic MAC protocols.This protocol divided the long preamble into lots of small ones embedded with destination address to avoid crosstalk,and adjusted nodes sleep cycle according to traffic loads dynamically,and chose proper backoff time to avoid message collisions on the basis of nodes' priority.Simulations demonstrate that LCT-MAC is superior to both S-MAC and LPL in aspects of network latency,energy consumption as well as message collision,and has a good performance.
