Asynchronous logic is a hot topic due to its interesting features of power saving, low noise and robustness to parameters variations. However, its performance analysis is relatively complex. In fact, the handshaking protocol strongly influences the performance of the pipelined architectures. This paper introduces verified Standard-Logic schematics for QDI asynchronous latches and analyzes their...

In this paper we present McMAC, a lightweight, low power and multi-channel MAC protocol for duty cycled Wireless Sensor Networks (WSNs) based on the strobed preamble sampling technique first presented in XMAC. Although many MAC protocols for duty cycled WSNs have been proposed so far, McMAC is the first protocol, to the best of the authors’ knowledge, that exploits in a lightweight fashion para...

In this paper, we propose a hybrid medium access control protocol (H-MAC) for wireless sensor networks. It is based on the IEEE 802.11’s power saving mechanism (PSM) and slotted aloha, and utilizes multiple slots dynamically to improve performance. Existing MAC protocols for sensor networks reduce energy consumptions by introducing variation in an active/sleep mechanism. But they may not provid...

European Rail Traffic Management System (ERTMS) is the European reference for interoperable and safer signaling systems to efficiently manage trains running. If implemented, it allows trains cross seamlessly intra-European national borders. ERTMS has defined a secure communication protocol, EURORADIO, based on open communication networks. Its RadioInfill function can improve the reaction of the...

In this paper, we propose an asynchronous duty cycle adjustment MAC protocol, called ADCA, for the wireless sensor network (WSN). ADCA is a sleep/wake protocol to reduce power consumption without lowering network throughput or lengthening transmission delay. It is asynchronous; it allows each node in the WSN to set its own sleep/wake schedule independently. The media access is thus staggered an...

Data Processing is an important issue in wireless sensor networks (WSNs). However, constrained energy will lead to the network life deeply affected by the power consumption of data processing. Hence, reducing the power consumption becomes an important objective to improve the performance of WSNs. In this paper, an energy-efficient data processing scheme (EED) is proposed to reach the goal of sa...

As processor power density increases, thermal and power control becomes critical for packet processing. Network applications feature ON/OFF execution pattern, which causes frequent temperature and power consumption changes in the processor. In this paper, we propose a novel power aware thermal management algorithm, which achieves power saving in multicore processors by employing a vacation sche...

Use of Wireless sensor networks have been widely seen in the fields of target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems.In wireless sensor networks nodes work with a incomplete power source, energy efficient operations in an important factor of the nodes in wireless sensor network. Energy conservation plays important role in different ...

We analyze the power saving operation called Discontinuous Reception (DRX) with a novel bursty packet arrival model in 3GPP Long Term Evolution (LTE)-Advanced networks. Typical analytical studies on the power saving operations in wireless networks have been carried out under the assumption that an expectation of exponentially distributed packet arrival intervals stays unchanged. However, practi...
