Abstract:
Objective To bring out a MAC protocol for the wireless physical signal detection system. Methods This paper studied the PCF mode in the 802.11 protocol, and gives some advices for future work according to the wireless monitoring system's character. Results The node in the system can reduce interception time, save energy and prolong life by using dynamic length superframe. Conclusion The result of the experiment shows that the system using the new protocol can improve the network capacity, reduce delay, and save energy.
