Medium access control(MAC)protocols have a significant effect on the function and performance of wireless sensor networks.This paper studies MAC protocols for clustered wireless sensor networks.Based on their shortcoming,it presents a new MAC protocl for clustered wireless sensor networks(C-MAC).C-MAC dynamically changes the length of TDMA frame according to the number of cluster member and traffic load,reduces the idle listening and improves channel utility,thus prolongs network lifetime.The simulation results show that this protocol has improved a lot in the delay of packets,energy consumption and the reception rate of the packets.
