5G-XHaul: a converged optical and wireless solution for 5G transport networks
(2016)The common European Information and Communications Technology sector vision for 5G is that it should leverage on the strengths of both optical and wireless technologies. In the 5G context, a wide spectra of radio access ... -
An adaptable LTE turbo decoder for indoor/low range outdoor environment: A study on low bit rates
(2015)In this work we study an adaptable SOVA/log-MAP turbo decoder for LTE mobile standard and flat Rayleigh fading channel. Particularly, this decoder is shown to adapt dynamically to different service scenarios, considering ... -
Asymptotically optimal policies for wireless networks with rechargeable batteries
(2008)We consider the problem of cross-layer resource allocation for single-hop, time-varying, wireless networks operating with rechargeable batteries under general arrival, channel and recharge processes. The objective is to ... -
Auction-based scheduling of wireless testbed resources
(2014)Experimentation in testbeds is gaining increasing ground as a necessary validation step for every theoretical study in communication networks. However, the first-come-first-served policy employed today by most testbeds ... -
Block error rate performance of OOK freespace optical links over gamma-gamma turbulence channels with generalised nonzero boresight pointing errors
(2018)The authors consider a point-to-point optical wireless communication link with on-off keying (OOK) modulation scheme. The propagation is deteriorated by the joint effects of gamma-gamma atmospheric turbulence and misalignment ... -
Building virtual 802.11 testbeds towards open 5G experimentation
(2016)Together with recent advancements in Radio Access Network (RAN) technologies, Wi-Fi is expected to be at the center of research on the subject of ubiquitous wireless connectivity, towards building the new 5G ecosystem. ... -
C2M: Mobile data offloading to mesh networks
(2014)As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In ... -
A class of multi-carrier CDMA access methods for wide-bandwidth wireless channels
(2005)In this article we describe and evaluate a general class of synchronous multi-carrier CDMA methods. In the proposed methods each accessing user is encoded by a Hadamard sequence and a multi-carrier (MC) encoder. The ... -
Cloud-based convergence of heterogeneous RANs in 5G disaggregated architectures
(2018)Cloud-RAN based architectures are widely considered a fundamental part of 5G networks. As a consequence, in the upcoming standards for 5G RAN, disaggregating the RAN functionality between a Central Unit (CU) and multiple ... -
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ... -
Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ... -
Cooperative approaches for dymanic wireless charging of Electric Vehicles in a smart city
(2014)In this paper, a method of electric vehicles charging with the use of large truck/bus vehicles moving along national highways and provincial roads is proposed and described. The method relies on charging vehicles from ... -
Cooperative handoff in wireless networks
(2008)In 802.11-based wireless networks the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes the STAs get information about the active APs in their ... -
Cooperative live video multicast for small cell base stations with overlapping coverage
(2016)In this paper, we present a cooperative video multicast protocol for densely deployed small cells. We assume that the small cell Base Stations (BS) have overlapping coverages and they are allowed to have interfering ... -
A cooperative protocol for video streaming in dense small cell wireless relay networks
(2015)The small-cell wireless network (SCN) paradigm is based on the deployment of low-power small cells close to the user so that spatial re-use is increased. Small cell base stations (SCBSs) can be connected either with a wired ... -
