“…CSMA-MPS [26] is essentially a combined version of Wise-MAC and X-MAC with better energy performance than both of them, which can be observed by comparing Table III, IV and V. With early ACK, MPS-PSR requires less energy than Wise-PSR in Table V as expected. Like Wise-PSR, the efficiency improvement of MSP-PSR increases as the traffic load decreases, because of the power of skew estimation and on-demand recalibration brought about by PSR.…”

“…We implemented the PSR design as an non-intrusive supporting layer with four low-duty-cycle MAC protocols (i.e., X-MAC [6], RI-MAC [28], Wise-MAC [25], and CSMA-MPS [26]) as illustrated in Fig.15, and evaluated their performance with test-bed experiments (using 24 MicaZ nodes coupled as 110 different node pairs) as well as an extensive simulation study obeying real world conditions.

Abstract-Low-duty-cycle radio operations have been proposed for wireless networks facing severe energy constraints. Despite energy savings, duty-cycling the radio creates transient-available wireless links, making communication rendezvous a challenging task under the practical issue of clock drift. To overcome limitations of prior work, this paper presents PSR, a practical design for synchronous rendezvous in low-duty-cycle wireless networks. The key idea behind PSR is to extract timing information naturally embedded in the pattern of radio duty-cycling, so that normal traffic in the network can be utilized as a "free" input for drift detection, which helps reduce (or even eliminate) the overhead of traditional time-stamp exchange with dedicated packets or bits. To prevent an overuse of such free information, leading to energy waste, an energy-driven adaptive mechanism is developed for clock calibration to balance between energy efficiency and rendezvous accuracy. PSR is evaluated with both test-bed experiments and extensive simulations, by augmenting and comparing with four different MAC protocols. Results show that PSR is practical and effective under different levels of traffic load, and can be fused with those MAC protocols to improve their energy efficiency without major change of the original designs. I. INTRODUCTIONIn wireless networks with severe energy constraints, e.g., wireless sensor networks [1], low-duty-cycle radio operations have been proposed as one of the major techniques to elongate the network lifetime [5], since the radio can be a main source of energy consumption [13]. Basically, the RF module of a node stays active only for a small percentage of time during each duty-cycle period (e.g., 1%), while keeps in low-energy sleep/off mode for the rest of the time [5][28]. Low-duty-cycle radio activity has been favorable in applications such as environment monitoring (e.g., Redwood [3], GreenOrbs [9]), animal observation (e.g., Great Duck Island [10]), civil structure surveillance (e.g., Mine [11]), etc. In all those applications, low-duty-cycle networking provides a nice trade-off between service quality and energy cost; however, it also brings about transient-available radio links that are essentially at odd with highly efficient communication. This is because in low-dutycycle networks, two nodes located within each other's radio range can communicate only when both of them are active simultaneously for transmitting (TX) and receiving (RX) [12]. A problem called communication rendezvous [17].Many smart ideas have been proposed for the rendezvous task in low-duty-cycle wireless networks. They usually function at the MAC layer and can be categorized into two general classes: (i) asynchronous [5]

Abstract. Nodes in a wireless network transmit messages through a shared medium. Thus, a Media Access Control (MAC) protocol is necessary to regulate and coordinate medium access. For some application areas it is necessary to have a deterministic MAC protocol which can give guarantees on message delay and channel throughput. Schedule based MAC protocols, based on time synchronization among nodes, are currently used to implement deterministic MAC protocols. Time synchronization is difficult and costly, especially in energy constrained sensor networks. In this paper the f-MAC protocol is presented which can give guarantees regarding message delay and channel throughput without the requirement of time synchronization among nodes. The various trade-offs of f-MAC are analysed and discussed and application areas that would benefit from f-MAC are presented.

“…In Berkeley Wireless Research Lab different nodes have been built, from the MICA family now commercially available to the smart dust nodes (Warneke, 2001) showing some future concepts far beyond state of the art. The sensor node built at our department uses only commercially available components but relies on high bit rate transceivers with a short turnaround time and a very efficient CSMA protocol for low throughput applications (Mahlknecht and Rötzer, 2004;Mahlknecht and Böck 2004). Within the EYES project, Infineon has developed highly efficient Wireless Sensor Network node hardware in collaboration with the project partners, particularly with TU Berlin and Universities of Ferrara and Rome (Eyes, 2005).…”

Abstract-The goal of the PAWiS project is to develop both, efficient system architectures and the related design methodology for power aware Wireless Sensor and Actor Network nodes that allow for capturing inefficiencies in every aspect of the system. These aspects include all layers of the communication system, the targeted class of the application itself, the power supply and energy management, the digital processing unit and the sensor-actor interface. The proof of concept will be based on a prototype system that allows a future integration in a single SiP/SoC. The project is supported by Infineon Austria and started only recently, therefore the main focus of this paper is on the design approach and issues related to the system level.
