favorite4In on embodiment, it provides connectivity between the support engine and any entity pertaining to the tactile edge, e.g., the tactile device or the gateway node and the network controller.
favorite2The scope of the baseline standard is to define a framework for the Tactile Internet, including description of its application scenarios, definitions and terminology, technical assumptions, architecture and reference models, and functional capabilities.
favorite12In order to provide a medium for delivering haptic and control information in real-time, the Tactile Internet requires highly reliable, responsive, and intelligent wireless connectivity.
favorite43The article provides an in-depth treatment of various architectural aspects including the key entities, the interfaces, the functional capabilities and the protocol stack.
favorite37While an extra overhead may be generated by the essential intra-group signaling messages, its impact on the macro cell RAN can be minimized or even removed by exploiting unlicensed spectrum technologies, namely D2D outbound communication, by means of for e.g. To achieve an optimal energy efficiency performance, the process of clustering and GC selection is usually carried out at the BS, where cell-wide Channel Status Information (CSI) is available to support a global optimization.
favorite27In this work, we rely on the unreliability of D2D links, and thus enhance the D2D-based grouped RA methods considering both a protocol extension and an architectural solution to efficiently handle access congestion issues in 5th Generation (5G) sensor networks.
favorite1In this context, this paper introduces a novel grouping-assisted random access protocol by shedding the light on beneficial performance and potential limitations of our solution against tunable parameters such as group size, number of sensors and reliability of D2D links.
favorite0This has attracted huge interest from the research community as many existing works focus on the radio access network (RAN) congestion control to efficiently manage resources in the context of device-to-device (D2D) interaction in huge sensor networks.
favorite557By meaningfully distributing spectrum among a number of network operators, a balanced market is targeted, which is attractive both for the society (other businesses, users, etc.)
favorite37We will now construct a competitive self-regulating  cellular telecommunications market, following the stated separation of powers, by introducing the society spectrum.
favorite5The regulatory primary interest is to assure a sustainable functioning of the respective market where sufficient competition is in place in order to balance the interests of involved stakeholders (telecom operators, content providers, business users, consumers, etc.).
favorite2Following the position in  the present work intermingles spectrum markets as commons and exclusively operated alternatives in order to dynamically react to market conditions, and hence to reduce the need for regulatory interventions.
favorite2Another battle ground  emerges around spectrum competition constellations in the unlicensed spectrum and its intermingling with licensed technologies (i.e., LTE-U) that aim at competing with Wi-Fi. Under these circumstances, the work of regulatory bodies has become tremendously difficult, aiming to support (at the same time): 1) Incentives to invest in state-of-the-art infrastructure covering the majority of the population and the considered geographical area; 2) The creation of reasonable market pressures protecting the interests of consumers, which includes mechanisms to avoid typical market failures and markets issues such as collusion, too high or too low competition, myopic investment decisions, etc.
favorite7The challenges include poor Wi-Fi coverage due to high power signal from cellular services and running of long data cables to backhaul the traffic towards an access controller..
favorite2Market is thus ripe for a planning tool that can address the needs of data offloading on hotspots not just by planning access points but engaging overlay layers of 3G/LTE to recommend possible candidate locations.
favorite1C. Availability and Limitations of Wi-Fi Planning Tools Once the potential areas have been identified through physical survey based on the data traffic distribution from the cellular network, there is a need to plan the deployment of Wi-Fi access points.
favorite3An integrated data offload approach provides the operator with full control over subscribers as well as the ability to deliver any subscribed content while the users are on the Wi-Fi network.
favorite0In this article, we carry out a survey of the practical challenges faced by operators in data traffic offloading to Wi-Fi networks.
