Smart metering IoT applications are among the most energy-critical in the current panorama. Metering sensors are battery-powered and are expected to have a lifetime exceeding ten years. In order to achieve such long operation duration, a generic header compression mechanism named Static Context Header Compression (SCHC) has been introduced and acce...

Data messages such as data packets in an IPv4 or IPv6 format are processed with a view to compression/decompression, using information obtained from sources other than the data packet itself, or the stream to which it belongs. This may involve additional dynamic processing defined in specifications identified by a shared marker, or obtained from an...

The Internet-of-Things (IoT) landscape is expanding with new radio technologies. In addition to the Low-Rate Wireless Personal Area Network (LR-WPAN), the recent set of technologies conforming the so-called Low-Power Wide Area Networks (LP-WAN) offers long-range communications, allowing one to send small pieces of information at a reduced energy co...

A new breed of wireless technologies has emerged under the generic name of low-power, wide-area (LPWA), with a number of common characteristics that make these technologies uniquely suitable for Internet of Things (IoT) applications. These common characteristics include a power-optimized radio network, a simplified network topology, frame sizes in...

This paper models a non-cooperative game between two EV charging stations. One is a fixed-power charging station purchasing electricity from the grid at wholesale price and reselling the energy to EV owners at a higher retail price; the other is regulation-providing and varies the recharging power level of its clients to provide regulation services...

Energy efficiency of wireless cellular networks is a well-studied domain and many proposals have been done following different amelioration paths. In this paper, we analyze the efficient use of small cells in a renewable energy context and considering real-time price of grid energy. This is typically the case when the mobile network is powered by t...

Up to recently, two main approaches were used for connecting the "things" in the growing Internet of Things (IoT)-one based on multi-hop mesh networks , using short-range technologies and unlicensed spectrum, and the other based on long-range cellular network technologies using corresponding licensed frequency bands. New type of connectivity used i...

The soaring electricity demand due to Electric Vehicles (EVs) increases the urgency of the evolution from the power grid to the so-called smart grid, to manage demand peaks with minimal infrastructure costs.

The soaring electricity demand due to Electric Vehicles (EVs) increases the urgency of the evolution from the power grid to the so-called Smart Grid, to manage demand peaks with minimal infrastructure costs. In this paper, we propose an approach close to Vehicle-to-Grid, where EVs can give back some energy from their batteries during peak times. Bu...

Electric Vehicles (EVs), as their penetration increases, are not only challenging the sustainability of the power grid, but also stimulating and promoting its upgrading. Indeed, EVs can actively reinforce the development of the Smart Grid if their charging processes are properly coordinated through two-way communications, possibly benefiting all ty...

Powering cellular base stations with renewable energy are one of the long-term strategies for achieving green networks and reducing their operational costs. As an energy provider, the power grid is evolving into a smarter one, which allows more energy-efficient cellular networks and enables cooperation and interaction with the smart grid. On one ha...

Electric Vehicles (EV) are drawing tremendous attention, as part of the transition toward environment-friendly transportation. While EV recharging represents a considerable extra load on the grid, they also offer new opportunities in terms of consumption flexibility. In this paper, we use the recharging process of EVs to provide regulation to the g...

The new standard for narrowband PLC-based communications IEEE P1901.2 defines two mechanisms which do not exist in the majority of its wireless counterparts — dynamic frequency mapping (tone mapping), and existence of several modulations. Until now, the benefit of these mechanisms was not taken explicitly into account by the routing protocols. In t...

One of the most promising techniques to drastically reduce the energy consumption of cellular networks is the use of sleep-mode (SM) methods: when the traffic load is low, some components of the network, such as a base station (BS), can be switched off. In this case, the traffic load is managed by BSs that stay on. In this paper, we investigate how...

In this paper, we propose to reduce the energy consumption of cellular networks by leveraging coordinated cell switching algorithms with user cooperation. Cell switching consists in deactivating some base stations in periods of low load in order to reduce the power consumption, while the coverage is provided by remaining active base stations. We pr...

Recently, renewable energy (RE) has been introduced as a promising solution to reduce the "non-green" energy consumption of cellular networks.

The backbone of this effort is the facilitation of info...

The network reconfiguration (NR) techniques are key strategies to reduce the energy consumption in cellular networks. In this paper we propose a mechanism to further increase the energy gains resulting of the application of these strategies. Our approach exploits the delay tolerance of the users to increase the periods when no reconfiguration is ne...

The extension of communication devices and the proliferation of transmission medium in home network contribute to increase the electromagnetic noise in home environment in general and in some area more specifically.
