Energy Efficient MAC Protocol for Low-Energy Critical Infrastructure Monitoring Networks Using Wakeup Radio
Critical infrastructure monitoring applications are rapidly increasing. Application requirements include reliable data transfer, energy efficiency, and long deployment lifetime. In this paper, the authors present a Medium Access Control (MAC) protocol for Low-Energy Critical Infrastructure Monitoring (LECIM) applications. The proposed MAC protocol is based on a framed slotted aloha multiple access schemes. For downlink communication, they use a wakeup radio approach to avoid complex bookkeeping associated with the traditional MAC protocols. Analytical expressions for power consumption and delay are derived to analyze and compare the performance of their proposed protocol with the existing well-known T-MAC, B-MAC, X-MAC, ZigBee, and Wise MAC protocols. It is shown that their proposed protocol outperforms all the other protocols in terms of power consumption and delay.
