In this paper, we propose a low-power multi-hop data-frame transmission scheme to realize a long-lived SUN (smart utility network) as promoted by the IEEE 802.15 TG4g group, and MAC modifications in the existing IEEE 802.15.4 MAC in order to support the TG4g PHY amendment. In the proposed scheme, turned-off beacons are employed in the superframe structure to reduce power wastage due to periodic transmission, and the existing concepts of active and inactive periods in 15.4 MAC are adopted; thus, effective sleep periods for each meter device are assigned. Moreover, by constructing a tree-shaped topology with incoming and outgoing superframes as defined in 15.4 MAC, multi-hop frame transmission is easily realized according to the topology. Furthermore, we propose a dynamic re-association procedure for optimizing the allocated active period and achieving low power consumption over the entire system. The results of computer simulation confirm that the proposed system allocates suitable active periods according to frame traffic while maintaining low power consumption.

We focus on the energy spent in radio communication by the stations (STAs) in an IEEE 802.11 infrastructure WLAN. All the STAs are engaged in web browsing, which is characterized by a short file downloads over TCP, with short duration of inactivity or think time in between two file downloads. Under this traffic, Static PSM (SPSM) performs better than CAM, since the STAs in SPSM can switch to low power state (sleep) during think times while in CAM they have to be in the active state all the time. In spite of this gain, performance of SPSM degrades due to congestion, as the number of STAs associated with the access point (AP) increases. To address this problem, we propose an algorithm, which we call opportunistic PSM (OPSM). We show through simulations that OPSM performs better than SPSM under the aforementioned TCP traffic. The performance gain achieved by OPSM over SPSM increases as the mean file size requested by the STAs or the number of STAs associated with the AP increases. We implemented OPSM in NS-2.33, and to compare the performance of OPSM and SPSM, we evaluate the number of file downloads that can be completed with a given battery capacity and the average time taken to download a file.

In this paper we numerically study the topology robustness of power grids under random and selective node breakdowns, and analytically estimate the critical node-removal thresholds to disintegrate a system, based on the available US power grid data. We also present an analysis on the node degree distribution in power grids because it closely relates with the topology robustness. It is found that the node degree in a power grid can be well fitted by a mixture distribution coming from the sum of a truncated Geometric random variable and an irregular Discrete random variable. With the findings we obtain better estimates of the threshold under selective node breakdowns which predict the numerical thresholds more correctly.

The proliferation of wireless communications systems poses new challenges in terms of coexistence between heterogeneous devices operating in the same frequency bands. In fact, in case of high-density concentration of wireless devices, like for indoor environments, the network performance is typically limited by the mutual interference among the devices themselves. For instance, this is the case for Wireless Local Area Network (WLANs). In this paper, we present a novel protocol strategy for managing multiple access in wireless networks. Namely, a control layer utilizing the UWB(ultra-wideband)-IR (impulse radio) technology is proposed for enhancing coexistence in WLAN systems. In this context, the UWB-based control layer is exploited for managing medium access in a coordinated way and for assigning and scheduling resources in order to optimize the WLAN data traffic. In this work, we perform a feasibility study regarding the proposed technical solutions, in particular verifying the compatibility of the UWB-IR technology with the WLAN-related range requirements and investigating the corresponding trade-offs.

Diversity techniques are of importance in the context of cognitive radio networks since they enable the primary and secondary terminals to simultaneously and efficiently share the spectral resources in the same location. In this paper, we investigate a simple, yet powerful, diversity scheme based on the exploitation of the polarimetric dimension. More precisely, we consider a scenario where the cognitive terminals use cross- polarized communications with respect to the primary users. Our approach is network-centric, i.e., the performance of the proposed dual- polarized system is investigated in terms of link throughput in the primary and the secondary networks. Our results suggest that the polarimetric dimension represents a remarkable (and simple to implement) opportunity in the context of cognitive radio networks.

Cognitive Radio (CR) enables an unlicensed user to change its transmission and reception parameters adaptively according to spectrum availability in a wide range of licensed channels. The concept of a Cognition Cycle (CC) is the key element of CR to provide context awareness and intelligence so that each unlicensed user is able to observe and carry out an optimal action on its operating environment for performance enhancement. The CC can be applied in various application schemes in CR networks such as Dynamic Channel Selection (DCS), topology management, congestion control, and scheduling. In this paper, Reinforcement Learning (RL) is applied to implement the conceptual of the CC. We provide an extensive overview of our work including single-agent and multi-agent approaches to show that RL is a promising technique. Our contribution in this paper is to propose various application schemes using our RL approach to warrant further research on RL in CR networks.

A sub-band based ultra wideband (SUWB) system is proposed for energy efficient short range wireless communications. The proposed technique divides the bandwidth of 500 MHz into number of sub-bands that may be utilized for higher data rate or higher reliability or multi user access depending on system requirements. The energy efficiency is achieved by reducing the sampling rate requirements and also by the use of an orthogonal code based interference rejection and multi-path cancellation receiver. An interference rejection method is also proposed to further enhance the performance of the system for high data rate and/or high delay spread channels. This results in a low power and low complex alternative to improve performance in comparison to the conventional equalization methods. The simulation results in terms of the BER performance of the method for the IEEE 802.15.4a channel models are presented. A significant improvement in SNR of 5-7 dB is reported with the incorporation of the interference rejection filter for low and medium delay spread channels.

Optimizing energy consumption is the main concern for designing and planning the operation of the Wireless Sensor Networks (WSNs). Clustering technique is one of the methods utilized to extend lifetime of the network by applying data aggregation and balancing energy consumption among sensor nodes of the network. In this paper, we propose the recently developed, Harmony Search Algorithm (HSA) for minimizing the intra-cluster distance and optimizing the energy consumption of the network. HSA is music based meta-heuristic optimization method which is analogous with the music improvisation process where musician continue to polish the pitches in order to obtain better harmony. A comparison is made with the well known cluster-based protocol approach developed for WSNs known as Low-Energy Adaptive Clustering Hierarchy (LEACH), heuristic optimization algorithms like Particle Swarm Optimization (PSO) and Genetic Algorithm(GA) as well as the traditional K-means and Fuzzy C-Means (FCM) clustering algorithms. Simulation results demonstrate that the proposed protocol using HSA can reduce energy consumption and improve the network lifetime.

The fact that the IEEE 802.15.4 MAC does not fully satisfy the strict wireless body sensor network (BSN) requirements in healthcare systems highlights the need for the design of new scalable MAC solutions, which guarantee low-power consumption to all specific sorts of body sensors and traffic loads. While taking the challenging healthcare requirements into account, this article aims at the study of energy consumption in BSN scenarios. For that purpose, the IEEE 802.15.4 MAC limitations are first examined and other potential MAC layer alternatives further explored. Our intent is to introduce energy-aware radio activation polices into a high-performance distributed queuing medium access control (DQ MAC) protocol and evaluate its energy-saving achievements, as a function of the network load. To do so, a fundamental energy-efficiency theoretical analysis for DQ MAC protocols is hereby for the first time provided. By means of computer simulations, its performance is validated using IEEE 802.15.4 MAC system parameters. The achieved outcome shows that the proposed DQ MAC scheme outperforms IEEE 802.15.4 MAC energy efficiency in all possible BSN scenarios.

An arc fault circuit interrupter (AFCI) is a device that provides protection from the effects of arc faults by de-energizing a circuit within a specified time after an arc fault is detected. In the United States, AFCI installation in bedroom receptacle outlets has been mandated since 2002. As AFCIs have been widely adapted to real situations, several kinds of AFCIs have been developed including branch/feeder, cord, outlet box, and portable designs. Using various types of AFCIs creates a hierarchy consisting of multi-level AFCIs such as a portable AFCI serially connected to an outlet box AFCI. This multi-level AFCI structure causes a serious problem by enabling an upper level AFCI to detect an arc fault occurring in the surveillance area of lower level AFCIs. This problem results in de-energizing the whole area covered by the upper level AFCI. In this paper, we propose a solution to the multi-level AFCI problem that occurs when several types of AFCIs are used in the same hierarchy. To provide a practical solution, we first present the theoretical background of a multi-level AFCI and suggest a solution that integrates collaborative communication and computing power into a conventional AFCI device. Finally, we introduce a prototype implementation of our approach. Our proposed approach can protect people and facilities against electrical fire hazards, which is one of major challenges that the smart grid aims to overcome using information technology.
