In this paper, we present a routing protocol design and implementation for the Advanced Metering Infrastructure (AMI) in Smart Grid. The proposed protocol implementation is based on the framework of the IPv6 Routing Protocol for Low Power and Lossy Networks (RPL), which is proposed by IETF and currently still in its design phase. RPL is based on the idea of maintaining a directed acyclic graph (DAG) structure for the network. We provide a practical implementation of RPL with a number of proper modifications so as to fit into the AMI structure and meet stringent requirements enforced by the AMI. In particular, we propose a novel DAG rank computation method and a reverse path recording mechanism, which enables real-time automated meter reading and real-time remote utility management in the AMI. Our proposed routing protocol design for AMI networks is validated through extensive simulations.

Traffic safety can be improved by using a vehicular dedicated communication protocol. The standard IEEE 802.11p is being developed for this purpose. The physical layer properties of this draft are based on the already widely used IEEE 802.11a standard. Nevertheless, the propagation conditions in vehicular communications are different to the ones considered for 802.11a, which is focusing on nomadic indoor usage, and well studied until now. In this paper we present the simulation results obtained from an implemented physical layer model for this standard. The used channel model describes the very peculiar characteristics of the vehicular radio channel, specially the nonstationarity. Several channel estimators are tested based on the pilot structure defined in the standard focusing on low complexity implementations. The results show that diffuse components, present in vehicular channels on highways, have a very significant impact on the system performance. Furthermore, in situations of poor line-of-sight contribution, an acceptable frame error rate is not achievable even at high signal-to-noise ratio values. Therefore, more complex channel estimation and equalization techniques based on the current standard pilot pattern have to be developed that are able to cope with the properties of the vehicular radio channel.

Network coding is becoming more and more popular in recent years for its ability to improve network throughput and robustness. In this paper, we propose a scheme of joint network coding and channel coding based on Turbo-BICM over multiple-access channel (MAC). The scheme with only a turbo decoder significantly reduces the complexity of system. Moreover, it can offer the best error performance in the high SNR regime. These conclusions are validated by both theoretical analysis and simulation results. Interesting, we also find that a detached scheme, which first operates channel coding then network coding, approaches the upper bound in the low SNR regime.

In this paper, an Urgency-based MAC (U-MAC) protocol, in which sensor nodes reporting urgent health information are given higher priority by cutting-off the number of packet retransmission of sensor nodes with non urgent health information, is proposed. The main consideration of this work is providing Quality of Service (QoS) support in medical wireless sensor networks through differentiating nodal access to the medium. The proposed MAC protocol is mathematically analyzed considering a beacon-enabled star network configuration of the IEEE 802.15.4a standard at 2.4 GHz. The used wireless body area network (WBAN) consists of N sensor nodes controlled by a single network coordinator. The obtained performance results show the capability of the proposed UMAC protocol in providing service differentiation in medical WBAN. Also, the results show that the number of critical nodes that can be supported by WBAN and their packet arrival rates decrease as the number of packet retransmission of such nodes is increased.

Distributed antenna systems(DAS) are techniques to improve the coverage and capacity of wireless system by reducing large scale fading of wireless channels. It is especially effective in noise limited scenarios, e.g. uplink transmission. In this paper, we propose a DAS layout where multiple sectorized antennas are located at the corners of hexagonal sectors. These distributed antennas are connected with a central unit within a sector via optical fibers. Only the signals received by distributed antennas within a sector are jointly processed. The power consumption and spectrum efficiency of several uplink transmission schemes in the proposed DAS layout are evaluated and compared with those in centralized antenna systems(CAS) in multi-cell environment. Compared with the baseline in the CAS layout, user equipment(UE) in the proposed DAS layout can spare the power consumption by as much as 16.25dB suppose the same spectrum efficiency threshold. Or equivalently, average and 5% outage spectrum efficiency are improved by as much as 226% and 209% respectively with same power consumption.

We propose a cognitive cooperative scheme based on cognitive relays in the downlink of a time division multiple access (TDMA) system. Cognitive relays utilize the spectrum holes detected via the spectrum detection to relay information, which can share the downlink slots through the frequency-division orthogonal transmission. Therefore, no extra system resources (slots or channels) are allocated for cooperation and the system encounters no bandwidth loss. Compared with the conventional cooperative scheme, the system throughput of our scheme can be significantly improved due to slot savings; however, our scheme suffers from outage performance degradation because the cognitive relays may not acquire spectrum holes or introduce interference from the licensed users of the spectrum as a result of acquiring spectrum "holes" by mistake. The analysis and simulation results suggest our scheme to achieve the system throughput gain at the price of the diversity performance loss.

This article studies the performance of M-ary phase shift keying (PSK) modulation schemes over mobile-to-mobile (M2M) fading channels with equal gain combining (EGC) in cooperative networks. The frequency-nonselective M2M fading channels are modeled assuming non-line-of-sight (NLOS) propagation conditions. Furthermore, a dual-hop amplify-and-forward relay type cooperative network is taken into consideration here. It is assumed that K diversity branches are present between the source mobile station and the destination mobile station via K mobile relays. The performance of M-ary PSK modulation schemes is analyzed by evaluating the average bit error probability (BEP). We have derived a simple analytical approximation for the average BEP of M-ary PSK modulation schemes over relay-based M2M fading channels with EGC. The validity and accuracy of the analytical approximation is confirmed by simulations. The presented results show that in a dual-hop relay system with EGC, there is a remarkable improvement in the diversity gain as the number of diversity branches K increases.

We investigate different schemes for data dissemination in multi-hop ad-hoc networks using network coding. We study the performance of these schemes in terms of the completion time when a set of data packets must be disseminated from a single source to all nodes in a multi-hop network, i.e. a network where at least one node is several hops away from the source. Therefore some network nodes must relay information to other nodes that are farther away from the source. In this setting, a relay node does not send a particular data packet, but a linear combination of the packets that it has previously received. The selection of such relays has a significant impact on performance. We present a graphical simulator based on OpenGL that allows to study performance and illustrate the status of network nodes in real time during the dissemination of an image file. Features of real-life ad-hoc networks such as packet losses and collisions are taken into consideration in our simulator. Numerical results are presented for simple linear meshed networks and for arbitrary topologies. Results indicate that schemes promoting parallel non-interfering transmissions complete the dissemination process faster.

Contrary to previous works, we focus on cooperation and competition relationship and the interactive dynamic behavior between multiple primary users (PUs) and secondary users (SUs) in a multiple cognitive interference channel context. Because of different levels of context information perceived by different types of players, e.g. the PUs and the SUs, and unbalanced nature of the spectrum priority among the multi-SUs/Pus in this setting, we investigate capacity maximization using the Stackelberg game modeling approach. Especially, we analyze the multi-leaders and multi-followers case, and further give a one-by-one case for making this model clear. Some conclusions are given via theorems. In addition, we propose the distributed iterative water-filling algorithms (IWFA) for pursuing Nash equilibrium solution (NES) and the Stackelberg equilibrium solution (SES) with low implementation complexity after analyzing and deriving the newly formulated game model in detail. Simulations results verify the performance of the proposed approaches in this paper.

Synchronized phasor measurement based Wide Area Monitoring and Control (WAMC) system is becoming a reality within international research and development both in academia and industry. Timely and accurate data with high resolutions holds great promise for more responsible and advanced grid control and operation. Currently, most of the research focuses on the different control schemes and applications. A relatively less addressed aspect is the dependency of the WAMC system on the performance of the Information and Communication Technology (ICT) infrastructure, without whose support the projected functionalities of the WAMC systems will be not achieved. Possible delays brought by the complex data transfer and processing processes in WAMC systems are addressed in the first part of this paper. Thereafter, simulations where delayed Phasor measurements are fed to the Static Var Compensator (SVC) are conducted iteratively to detect its maximum tolerated delay. Furthermore, performance requirements for the centralized computation and control actuation are researched and analyzed based on simulation results. It also includes a study on feasibility of compensations using local signal based Power System Stablizers (PSS) in situations with much phasor data delay. The paper is concluded by suggesting ICT architecture for WAMC systems aiming to improve its robustness.
