Preamble Sampling MAC Protocols With Persistent Receivers in Wireless Sensor Networks

Free registration required

Executive Summary

The authors provide an analytical framework for preamble sampling techniques for MAC protocols in wireless sensor networks, from which they derive closed-form formulas for lifetime and reliability calculations. In addition to take into account transmitter behavior that controls the form and the content of the transmitted preamble, their model also considers receiver behavior that controls the duration of preamble reception in case of successful and failed reception. Along with both transmitter and receiver behavior, their model considers a non-perfect channel and thus takes into account the impacts of transmission errors and retransmissions on lifetime and reliability of preamble sampling protocols.
