3GPP Machine Type Communications (MTC) An Overview
The Third Generation Partnership Project (3GPP) has been working on developing specifications on Machine Type Communications (MTC), also known as Machine to Machine Communications (M2M). This is...
An in-depth Study on Smart Grids with special significance on South Korea
Smart Grid is an inevitable trend of power grid, and smart grid comprehensive assessment system can conduct a comprehensive assessment of the overall characteristics of smart grid, which can...
D2D Communications: Technology and Prospect
Next generation 5G networks contemplate to exploit millimeter Wave (mmWave) for a massive increase in data rates but its inherent characteristic of line-of-sight (LoS) brings up the challenge of...
DISASTER DETECTION AND RECOVERY
In this lecture, we will talk about the challenges of autonomous cell outage detection (COD) in Self-Organizing Networks (SON). COD is a pre-requisite to trigger fully automated self-healing...
Demand Response in Smart Grid
Smart grids are conceived of as electric power grids, capable of delivering electricity in a controlled,smart way from energy generator to active consumers. Demand response (DR), by promoting the...
Greening of Mobile Networks Myths and Opportunities
Next generation 5G wireless networks envision innovative radio technologies for ultra dense deployment with improved coverage and higher data rates. However, the deployment of ultra dense 5G...
Mobile Wi-MAX for Broadband Wireless Internet
Mobile WiMAX is a fast growing broadband access technology that enables low-cost mobile Internet applications, and realizes the convergence of mobile and fixed broadband access in a single air...
Modulation and Coding
In a digital communication system, the source to be transmitted is discrete both in time and amplitude. Digital information carrying signals must be first converted to an analog waveform prior to...
Next Generation 5G Wireless Networks
The vision of next generation 5G wireless communications lies in providing very high data rates (typically of Gbps order), extremely low latency, manifold increase in base station capacity, and...
Opportunities and Challenges in Machine-to-Machine Communications
Machine-to-machine (M2M) communications have emerged as a cutting edge technology for next-generation communications, and are undergoing rapid development and inspiring numerous applications....
Regulatory Issues in M2M Communications
Machine-to-machine (M2M) solutions are rolling out worldwide and across all industries - possibly being a key enabler of applications and services covering a broad range of vertical markets (e.g.,...
Resource Allocation in Cellular Network and HetNets
Heterogeneous wireless networks with small-cell deployments in licensed and unlicensed spectrum bands are a promising approach for expanding wireless connectivity and service. As a result,...
Traffic-Driven Power Saving in Operational 3G Cellular Networks
Base stations (BSes) in the 3G cellular networks are not energy proportional with respect to their carried traffic load. Our mea- surements show that 3G traffic exhibits high fluctuations both in...
Tutorial on OMNeT++ (Part-1)
