With the rapid development of radio technologies,low energetic consumption processor and chip integrated technology, wireless sensor networks emerge. Due to its low cost, good adaptability, powerful function, wireless sensor networks have wide and will be applied in many fields such as prospect, military,environmental protection, production, medicine, intellectual space, and so on.The communication protocol faces a lot of new challenges.This essay emphatically routing protocol and MAC(medium access control) protocol among the communication protocol,and raises research direction in the future.
Key words:wireless sensor networks,communication protocol,routing protocol,MAC(medium access control) protocol
