| Abstract: | This paper presented a new random multi-access MACprotocol for WSN,through dividing the 1 + a of packet transmit,using probability detection and 1-persistent control,gave the flow chart and part of program code,realized protocol on GAINZhardware platform.We analyzed multi-channel random multi-access WSNin terms of theory,then gave some import system parameters include throughput of system,delay of packet transmit and analyzed the energy efficiency.Then,we proved theoretical analysis was true through computer simulation experiment. |
