This paper introduces a Software Defined Network (SDN) architecture for 5G dense multi-infrastructure provider deployed wireless backhaul networks. The architecture contains a two-tier controller in a hierarchical setup aiming to offload some of the control functionalities from the central controller to a collection of logically distributed dynamically configured local controllers in order to balance...
The anticipated 1000 fold traffic growth in 2020 and the explosion of new services and applications including the massive Internet of Things, tactile internet, etc. pose tough challenges for the next generation mobile network. A soft end-toend solution from the core network to the radio access network, as well as the air interface is envisioned as the key to meet the extremely stringent demands. This...
One of the goals of 5G is to simplify the 4G core network and enable interworking across multiple Radio Access Technologies (RATs) without the addition of specialized network elements, protocols and interfaces that perform often redundant functions for each access technology. Achieving this reduces operator costs, and can improve the subscriber experience when devices can access multiple RATs. In...
Efficient discovery of multiple small cells is important to features such as small cell on/off, load balancing, CoMP (Coordinated Multi-point Transmission), e-ICIC (enhanced-Inter-Cell Interference Coordination) in LTE (Long Term Evolution) hyper-dense networks. However, severe interference in the Hyper-Dense Networks imposes great difficulty on efficient discovery of small cells. This paper proposes...
Cellular communications have witnessed an exponential growth over the last few years. The challenges the industry faces for the next decade arise the need for significant changes, i.e., new paradigms away from just incremental advances in the current technologies. Network densification and high frequency communications are widely-recognized as cornerstones of this revolution. Understanding the needs...
Carrier Aggregation (CA) is a promising solution to enhance peak throughput in LTE-Advanced or Small Cells Networks (SCN). Thanks to this technique, a terminal becomes able to transmit on one or multiple component carriers. However, many issues in terms of radio resource allocation and mobility should be addressed. In this paper, we aim at improving carrier component allocation during inter-cell handovers...
Cooperative transmission system is proposed approach to wireless communication for industrial use. This system is suitable for a factory channel environment, because it can prevent packet delay resulting from long term shadowing with maintaining low power consumption. In this paper, several simulations are made to investigate the packet delay and power consumption properties. They have been carried...
Providing data confidentiality for energyconstrained devices has proven to be a hard problem. Over the years many efficient implementations of well-known block ciphers, as well as a large number of new “lightweight” block ciphers, have been introduced. We propose to distribute block ciphers encryption and decryption operations between a subset of “trusted” nodes. Any block cipher, lightweight or not,...
This paper proposes a new approach to cope with the challenges in sensor localization in an obstructed environment even in the presence of channel noise. In particular, a progressive localization scheme is proposed that does not necessitate the need for any cluster as most existing schemes do. Initialization is done by generating a quadrilateral of sensor nodes where the connectivity weight between...
The Smart Grid (SG) is one of the latest emerging and rising models for modernizing traditional electrical power grids, and wireless communication is considered as a major building block in realizing SG. SG applications enable electrical devices to be interconnected and communicate with each other, requiring pervasive control of these actors. Therefore, wireless sensor network-based applications are...
With the proliferation of Internet of Things (IoT) devices such as smartphones, sensors, cameras, and RFIDs, it is possible to collect massive amount of data for localization and tracking of people within commercial buildings. Enabled by such occupancy monitoring capabilities, there are extensive opportunities for improving the energy consumption of buildings via smart HVAC control. In this respect,...
In this paper, a model for traffic jam prediction using data about traffic, weather and noise is presented. It is based on data coming from a Smart City in Spain called Santander. The project in this city is called ”Smart Santander” and provides a platform for large-scale experiment based on realtime data. This paper demonstrates the possibility of predicting traffic jams and is a basis to integrate...
The building energy consumption represent 60% of total primary energy consumption in the world. In order to control the demand response schemes for residential users, it is crucial to be able to predict the different components of the total power consumption of a household. This work provide a non intrusive identification model of devices with a sample frequency of one hertz. The identification results...
The automatic identification of appliances through the analysis of their electricity consumption has several purposes in Smart Buildings including better understanding of the energy consumption, appliance maintenance and indirect observation of human activities. Electric signatures are typically acquired with IoT smart plugs integrated or added to wall sockets. We observe an increasing number of research...
