Data interaction between power consumers and utilities is one of the distinctive features of smart grid. The smart meter plays a core role in data collection and transmission process, which is also considered as one of the most power consuming devices in the whole architecture of distribution power grid. With the large-scale distribution of smart meters in high-density residential communities and increasing data transmission, power saving of smart meter has recently become an attractive research topic in both academia and industry. In this paper, we propose a novel time sequence scheduling based power saving mechanism for controlling the data transmission between smart meters and a sub-data center located in the secondary substation in distribution grid, via establishing two-mode switch target zones in the local smart grid community. We also explore the relationship between the efficiency of power saving based on the new strategy and the number of divided target zones. Simulation results show high performance gian of 50% power saving rate on average, and applicability of the proposed strategy for data transmission in the smart grid when compared to the conventional power management scheme.

Device-to-Device (D2D) communication enables direct communication between nearby user devices using cellular or ad hoc links thereby improving the spectrum utilization, system throughput, and energy efficiency of the network. Exploiting mobile cloud based D2D communication architecture underlying LTE cellular network has a huge importance in reducing the transmission power of the UEs resulting an improved battery life. This paper proposes a novel hybrid D2D communication architecture where a centralized Software-Defined Networking (SDN) controller communicates with the cloud head (CH) in order to reduce the number of LTE communication links thereby improving energy consumption. In addition, UEs can participate and perform operations in multiple clouds simultaneously. The obtained simulation results confirm improved energy efficiency as compared to the legacy LTE network.

Fifth Generation (5G) networks will compromise of heterogeneous networks (HetNets) with macrocell overlaid with lower power small cells to achieve higher throughput by offloading users with low signal-to-noise-ratio from macrocell to the small cells. In this paper, we proposed a multi-objective optimization problem (MOP) to jointly investigate the tradeoff between throughput and backhaul energy efficiency (BEE) using ω-fair utility function for two different backhauling technologies in downlink transmission scheme of a two-tier HetNets. We then transform the proposed MOP into a single objective optimization problem (SOP) employing the weighted sum method to obtain the complete Pareto Frontier solution set with minimum QoS requirements and rate fairness level ω. The transformed SOP is solved in an iterative manner using Lagrangian Dual Decomposition (LDD) with a subgradient method providing a near-optimal solution. Simulation results demonstrate the effectiveness of our proposed approach in reducing the total area power consumption irrespective of the backhauling technology by dynamically adjusting weighting coefficient α and rate fairness level ω. Our numerical results also demonstrate the fundamental tradeoff between throughput and BEE for different parameters such as weighting coefficient α and rate fairness level ω.

Electric vehicles represent a promising choice to decrease pollution and reducing fossil fuel consumption. However, their limited autonomy poses a challenge that prevents them from being suitable for many car users. Several practical solutions are sought to avoid this problem, in particular one may think of enhancing the battery capacity, reducing the charging time, or increasing the frequency of charging points. In this paper, we discuss how these aspects can be integrated by a proper Markov model, thereby offering a neat analytical solution to investigate all these problems. Some preliminary results are also shown to demonstrate the descriptiveness of the model. Further investigation can frame the proposed contribution within an optimization framework, maintaining an analytical context.

Recent advances in computing and communication enable the concept of smart homes that contain programmable appliances. Knowing that most household tasks do not need to be performed at specific times, but rather within a preferred time period, this paper studies the problem of optimal power generation scheduling in an isolated Microgrid, exploiting the flexibility to schedule energy-consuming tasks in smart homes. We formulate the problem as a non-linear optimization problem and present two scheduling protocols to solve it: GA-INT, a genetic algorithm that utilizes task interruptions, and PRO-S, a heuristic-based algorithm, which strives to smooth out peaks in the load profile. Numerical simulations demonstrate that PRO-S successfully reduces the complexity of the problem, while guaranteeing performance that approximates GA-INT's. The latter returns optimal or nearly optimal solutions, but with long execution times.

Vector based forwarding (VBF) routing protocol is a location-based energy efficient routing protocol designed for underwater acoustic sensor networks (UASNs). In this paper a VBF-improved routing protocol is proposed, which uses not only the information of location but also the residual energy and the number of retransmission in last cycle to make decision whether to make data forwarding. According to the simulation results, more evenly energy consumption and reliable data transmission are achieved in our proposed protocol, compared to previous vector-based routing protocols for UASNs.

In this paper, a novel receiver is proposed for coded massive Multiple-Input-Multiple-Output systems using Orthogonal Frequency Division Multiplexing (MIMO-OFDM). The receiver utilizes log-likelihood ratios (LLR) derived from complex ratio distributions to model the noise probability density function (PDF) at the output of a zero-forcing detector. These LLRs are subsequently used to improve the performance of the decoding of Low Density Parity Check (LDPC) codes. The Neumann large matrix approximation is employed to simplify the matrix inversion in deriving the PDF. To verify the new findings, Monte Carlo simulations are used to demonstrate the optimality of the fitting between the derived PDF the experimentally obtained histogram of the noise. Further simulations results over time-flat frequency selective multi-path fading channels demonstrated improved performance over equivalent systems using the Gaussian approximation for the PDF of the noise. A significant gain of 1 dB was observed at bit error rate of 10-4 which corresponds to a reduction of approximately 30 receive antenna elements.

The Internet is evolving towards a two-fold architecture that will comprise of traditional infrastructure based networks as well as emerging self organised autonomic peripheral networks. Such Internet peripheral networks are being termed as the Internet of things (IoT) whereby smart objects and devices will be connected together in a fully distributed fashion to provide ubiquitous services through pervasive networking. Mobile Ad hoc Networks (MANETs) is regarded as one of the pervasive self-organised networks that will play a major role in autonomic future internet communication. There are several wellknown challenges to be addressed in order to enable MANET deployments of large islands of interconnected smart devices. Therefore, in this paper, we perform simulations using the ns-2 software, for various well-known routing protocols for MANETs in order to determine the scalability of these protocols. This paper analyses the scalability of the routing protocols with respect to routing overhead required by approaches while also considering the packet delivery latency, which is an important Quality of Service (QoS) metric.

A heterogeneous wireless network (HetNet) that consist of macro cells and massively deployed small cells within the same region is one of the solutions to increase network capacity. Cognitive small cells offer an attractive solution for HetNets to minimize the need for coordination between the macro and the small cells. Adequately associating users to the macro and the small cells is critical in heterogeneous wireless networks for load balancing, especially those with cognitive small cells. Ih this paper, we develop a scheme for load balancing in HetNets with cognitive small cells. Our scheme uses a model-based solution to estimate the load measured by the number of active users in cognitive small cells and balances load between the macro and small cells to avoid congestion in small cells. We use simulation to show the accuracy of our model-based solution and effectiveness of our solution.

Network densification is an essential mechanism expected to enable next generation 5G networks to meet the highly anticipated 1000-fold increase in capacity. This article examines the challenges facing network densification, in terms of interference, energy and mobility. Moreover, some of the key technologies envisaged as enablers for next generation network densification (i.e., cloud-radio access and user-centric mechanisms, advanced inter-cell interference cancellation techniques, device-to-device communications, caching, and separation of control and user plane) are discussed. The challenges and opportunities facing dense network deployments presented in this work are critical antecedents for the evolutionary stages of developing envisioned 5G networks.
