X-mac: A short preamble mac protocol for duty-cycled wireless sensor networks
- in SenSys
, 2006
"... In this paper we present X-MAC, a low power MAC protocol for wireless sensor networks (WSNs). Standard MAC protocols developed for duty-cycled WSNs such as B-MAC, which is the default MAC protocol for TinyOS, employ an extended preamble and preamble sampling. While this “low power listening ” approa ..."

RI-MAC: a receiver-initiated asynchronous duty cycle MAC protocol for dynamic traffic loads in wireless sensor networks
- in Proc. ACM SenSys
, 2008
"... The problem of idle listening is one of the most significant sources of energy consumption in wireless sensor nodes, and many techniques have been proposed based on duty cycling to reduce this cost. In this paper, we present a new asynchronous duty cycle MAC protocol, called Receiver-Initiated MAC ( ..."

decoupling the sender and receiver’s duty cycle schedules. We show the performance of RI-MAC through detailed ns-2 simulation and through measurements of an implementation in TinyOS in a testbed of MICAz motes. Compared to the prior asynchronous duty cycling approach of X-MAC, RI-MAC achieves higher
Practical Asynchronous Neighbor Discovery and Rendezvous for Mobile Sensing Applications

A load-aware energy-efficient and throughput-maximized asynchronous duty cycle MAC for wireless sensor networks
- Ann. Telecommun
"... Abstract Being a pivotal resource, conservation of en-ergy has been considered as the most striking issue in the wireless sensor network research. Several works have been performed in the last years to devise duty cycle based MAC protocols which optimize energy conservation emphasizing low traffic l ..."

Through extensive simulation using ns-2, we have evaluated the performance of LET-MAC. LET-MAC achieves significant energy
ENERGY USAGE REDUCTION IN WIRELESS SENSOR NETWORKS USING ASYNCHRONOUS DUTY CYCLE MAC PROTOCOL
"... Recent advances in Wireless Sensor Networks (WSN) have led to many new protocols specifically designed for different kinds of applications where energy efficiency is an essential consideration. Most of the attention has been given to the Medium Access Control (MAC) protocols since they play an impor ..."

Asynchronous physical-layer network coding,” technical report. Available: http://arxiv.org/abs/1105.3144
"... Abstract—A key issue in physical-layer network coding (PNC) is how to deal with the asynchrony between signals transmit-ted by multiple transmitters. That is, symbols transmitted by different transmitters could arrive at the receiver with symbol misalignment as well as relative carrier-phase offset. ..."

The framework can effectively deal with symbol and phase asynchronies while incorporating channel coding at the same time. 2) For unchannel-coded PNC, we show that for BPSK and QPSK modulations, our BP method can significantly reduce the asynchrony penalties compared with prior methods. 3) For QPSK unchannel
