Considering the time-varying power consumption of users and cost of generation over a day, demand side management (DSM) has become essential to meet the excessive need of users with the limited source of power. In this paper, we propose a utility based optimal Real-Time Pricing (RTP) mechanism for the future smart grid communication systems such that the electricity price corresponds to the optimum...
Smart city is gaining a significant attention all around the world. Narrowband technologies would have strong impact on achieving the smart city promises to its citizens with its powerful and efficient spectrum. The expected diversity of applications, different data structures and high volume of connecting devices for smart cities increase the persistent need to apply narrowband technologies. However,...
Conventional planning and optimization of cellular networks for supporting the peak-time user demand leads to substantial wastage of electrical energy. Therefore, we propose an energy-aware dynamic network provisioning framework for realizing green mobile cellular systems by reducing energy consumption in access networks. Proposed mechanism allows base stations (BSs) to offload their entire traffic...
The main problems of current cellular networks illustrating high delay and traffic congestion relate to their network inflexibility and incorporated control and data planes. However, the prerequisites of 5G cellular systems are low delay, high throughput, low congestion at the core cellular networks, and seamless mobility and fast handover. To alleviate aforementioned problems we propose a 3-Tier...
To cope with increasing mobile data traffic, researchers are currently working on traffic offloading techniques for delivering data over unlicensed cellular bands. Current offloading schemes based on offloading data to Wi-Fi regardless Wi-Fi has sufficient throughput or not. Though, we propose a novel offloading technique based on the Remaining Throughput Scheme (RTS) for Wi-Fi selection. In our proposed...
This paper considers a dual-hop wireless powered communication network (DH-WPCN), where the communication between a hybrid access point (HAP) and a number of users is assisted by energy-limited relays. In order to power relays for assisting the communication, the HAP broadcasts a dedicated energy signal in the downlink. Each relay harvests energy from this signal and utilizes the harvested energy...
Underwater wireless sensor networks are garnering a greater research interest as human's endeavor to investigate deeper into the depths of the ocean. However, infrastructure is currently lacking in underwater communications. Acoustic communications have been long the preferred method, however, as applications become more resource intensive, the low bit rates and high latency of acoustic communications...
Degradation of olive oil under light and heat are analysed using an optical fibre based low-cost portable smartphone spectrofluorimeter. Visible fluorescence bands associated with phenolic acids, vitamins and chlorophyll centred at λ ∼ 452, 525 and 670 nm respectively are generated using near-UV excitation (LED λex ∼ 370 nm), of extra virgin olive oil are degraded more likely than refined olive oil...
To make full use of space/air resources, a Space-Air Integrated Network (SAIN) which is a hierarchical network with satellites, airships and hovering Unmanned Aerial Vehicles (UAVs) is constructed. Nowadays, Free Space Optical (FSO) links have been widely applied in SAINs since they provide high-rate and large-capacity data transmission. Unfortunately, the FSO links across the atmosphere would perform...
Smart Grid (SG) is considered as an intelligent electricity delivery system due to its advantage of bi-directional mode of data and information flow. This improves the reliability, efficiency and self-controllability on the SG system. One of the important components in SG is the Smart Meter (SM). Its key function is to report power consumption to a centralized control center at regular intervals....
On behalf of the Technical Program Committee of the IEEE SmartGridComm2016, it is my great honor and pleasure to welcome you to the 7th IEEE International Conference on Smart Grid Communications. SmartGridComm 2016 takes place in the beautiful harbor city of Sydney on 6–9 November 2016. IEEE SmartGridComm 2016 will feature a technical program centered around four thematic symposia, namely Communications,...
The inclusion of a previously non-existent traffic class required by the Smart Grid poses many difficulties on OFDMA based wireless communication systems. In this paper, we develop a resource allocation algorithm based on the ecological research Lotka-Volterra equations. Each class of traffic is modelled as a species and they compete over the telecommunications resources. Constraints were then placed...
Mobility management in cellular networks, such as the Long Term Evolution (LTE) System, relies on a centralized anchor, which depends on both the control plane and data plane. Therefore, mobility management suffers from many limitations such as low scalability and a single point of failure. Distributed Mobility Management (DMM) overcomes previous limitations and can be applied for HetNets or DenseNets...
Coordinated multi-point (CoMP) transmission introduced by long-term evolution-advanced (LTE-A) cellular systems has shown great promise for improving network spectral efficiency (SE). On the other hand, the ever increasing energy consumption in cellular systems has emerged as a major concern for the network operators. This paper proposes a novel CoMP technique for the downlink of two-tier heterogeneous...
One of the critical components of the Smart Grid (SG) is the Smart Meter (SM), which reports power consumption to a centralized control center at regular intervals. The Long Term Evolution (LTE) network has received much attention as a promising platform for SG communications due to its high bandwidth and low latency over a large coverage area. Nevertheless, when a huge number of SMs access the LTE...
Acoustic, wave based underwater wireless sensor networks (UWSNs), commonly used for underwater surveillance and explorations, fail to meet the growing demand for fast detection and higher data rates. Electromagnetic (EM) wave based underwater networks; on the other hand, have great potential for supporting such stringent requirements for various applications. Therefore, this paper proposes and investigates...
Femtocells, which is one of the methods followed by 4/5G cellular system, are used for handling increasing data traffic in heterogeneous (HetNets) and dense networks (DenseNets). In this case, traditional mobility and session management approaches become obsolete and more appropriate methods need to be developed. Therefore, we propose a Distributed Mobility Management (DMM) and a User Rate-Perceived...
We propose a novel communication system for an emergency fire response team, which provides Internet service on the way to and in the disaster area. The system is composed of a multi-interface mobile ad-hoc network (MANET) router, a Global Positioning System (GPS) receiver, and two Wi-Fi interfaces with directional antennas, which can be easily attached to the roof of a vehicle. The front-side Wi-Fi...
Due to the relatively longer coverage capability, acoustic wave based underwater networks are commonly used for navigating autonomous underwater vehicles (AUVs). However, significantly slower propagation speeds of acoustic waves make the navigation of AUVs prone to substantial operational delay. Though electromagnetic (EM) signal suffers from severe attenuation in underwater environment, it can be...
Traffic demand in terms of total traffic volume and bit rate of mobile users is expected to increase exponentially over the coming years. As a result, current cellular networks are rapidly reaching their capacity limitations. Rescaling existing networks and protocols will not solve the problem due to a number of reasons. Firstly, the cost of upgrading backhaul networks is very high. Secondly, the...
