Typical coordination schemes for future power grids require two-way communications. Since the number of end power-consuming devices is large, the bandwidth requirements for such two-way communication schemes may be prohibitive. Motivated by this observation, we study distributed coordination schemes that require only one-way limited communications. In particular, we investigate how dual descent distributed...
Considering that full-duplex relaying (FDR) can achieve higher spectral efficiency than traditional half-duplex relaying (HDR), a spectrum sharing protocol based on FDR is proposed in this paper. We investigate a two-phase FDR spectrum sharing protocol in cognitive two-way relay networks. Analytical expressions for the outage probabilities of the primary and secondary systems under the proposed protocol...
In this paper, we provides a simple and accurate analysis by Markov chain modeling to evaluate the IEEE 802.11 DCF performance in the presence of capture effect. We extend the Bianchi's multidimensional Markov chain analytical model of IEE 802.11 DCF to characterize the behavior of DCF considering capture effect and packet retransmission limits. We compare the NS-2 simulation results with the derived...
One of the main challenges in Grid is efficient discovery of resources to the tasks submitted by users. Due to the lack of centralized control and the dynamic nature of resource availability, any successful discovery mechanism should be highly distributed and robust to the change in the Grid environment. In this paper, a research of resource discovery in a Grid environment has made on theory. We present...
With the development of ethernet technology, the requirement of time synchronization is becoming higher and higher on the distributed ethernet monitoring system. According to the requirement of bridge structure monitoring system, the distributed solution based on IEEE1588 protocol is presented after the research of IEEE1588 protocol and the explanation of principle on high precision synchronization...
