    In this paper, we consider user scheduling and relay selection with fairness concerns in a multi-source cooperative network, where sources take turns to deliver their information to the base station and then relays help to forward their corresponding source's message under system scheduling decision. We investigate the maximum achievable rate as the system objective and propose a suboptimal algori... View full abstract»

    Network sharing is a commonly used solution for macro cellular networks when mobile operators want to exploit benefits of sharing infrastructure, typically to save network costs. For local area and indoor networks infrastructure sharing using distributed antenna systems (DAS) and repeaters are commonly used solutions to improve indoor coverage. For these applications multi-operator solutions are w... View full abstract»

    We study in this paper the planning of DVB-NGH and LTE, both separately and in cooperation, for the offering of mobile TV service. For the case of standalone DVB-NGH, we show the trade-off between coverage and capacity. In the case of standalone LTE, we evaluate the need for expensive infrastructure deployment. In the DVB-NGH/LTE cooperative case, we investigate two scenarios: coverage extension a... View full abstract»

    Flow scheduling is crucial in the next-generation network but hard to address due to fast changing link states and tremendous cost to explore the global structure. In this paper, we first design a distributed virtual game to solve the optimization of flow scheduling problem assuming the priori knowledge of the distribution of edge cost as a random variable. In our virtual game, we use incentives t... View full abstract»

    We propose in this paper an enhanced Inter Cell Interference Coordination (ICIC) mechanism based on Multi Armed Bandit (MAB) approach that aims at maximizing not only the throughputs of the attached users but also their HandOver (HO) performances evaluated through 3GPP Mobility Robustness Optimization (MRO) indicators. To this end, the MAB procedure explicitly takes into account the HO performance... View full abstract»

    Multi-antenna processing first appeared in Digital Video Broadcasting in the 2nd generation terrestrial system DVBT2 by defining an optional MISO processing based on modified version of Alamouti codes in frequency domain. Decoding methods recommended by the DVB-T2 is the linear methods ZF and MMSE. In this paper we propose to use a modified K-Best Sphere Decoder (SD), to enhance the sys... View full abstract»

    This work aims at combining adaptive protocol design, utility maximization and stochastic geometry. We focus on a spatial adaptation of Aloha within the framework of ad hoc networks. We consider quasi-static networks in which mobiles learn the local topology and incorporate this information to adapt their medium access probability (MAP) selection to their local environment. We consider the cases w... View full abstract»

    Incremental redundancy hybrid automatic repeat request (IR-HARQ) scheme used in recent wireless communication standards such as 3GPP LTE provides higher benefits in terms of system capacity and robustness. To map these benefits into system level evaluations is of critical importance. Traditional link abstraction techniques are usually designed for a fixed bandwidth and do not present a generic sol...

    There exists a number of network measurement tools and web-based services for end users. Almost all of them focus on network bandwidth and possibly latency, and simply report the results to the user. This paper presents Netradar, a somewhat different measurement service. We analyze network bandwidth and latency but also over ten other parameters. We dwell into the data and show various coverage ma... View full abstract»

    This paper compares the Simple Genetic Algorithm (SGA) to the Triallelic Diploid Genetic Algorithm (TDGA) in evolving an anti-jamming beamforming array in situ. The SGA and TDGA are both able to find reasonable beamformer settings that thwart two stationary interferers while allowing reception of a stationary signal of interest (SOI). We evaluate the TDGA's performance in thwarting mobile interfer... View full abstract»

    Theoretical analysis of the IEEE802.11e enhanced distributed channel access (EDCA) mechanism is now a mature research theme and is receiving considerable attention. Most previous studies have focused on the saturation throughput, but typical networks are non-saturated in practice. We herein propose an analytical model for IEEE 802.11e EDCA under non-saturated conditions based on the frame-transmis... View full abstract»

    We study a multiple input multiple output (MIMO) cellular system where each base-station (BS) is equipped with a large antenna array and serves some single antenna mobile stations (MSs). With the same setup as in [1], the influence of orthogonal and non-orthogonal pilot sequences on the system performance is analytically characterized when each BS has infinitely many antennas. Using stochastic geo... View full abstract»

    Automated Self-optimizing Networks (SON) algorithms have been proposed to address and solve the issues related to optimization in small cell networks. However, automatic optimization approaches require precise knowledge of the deployment environment and users behaviors. This information is generally difficult, expensive to obtain and presents significant computational requirements. In this paper w... View full abstract»

    The existence of coverage holes in cellular networks is a common problem for mobile operators. Traditionally, the cellular coverage is computed using sophisticated planning tools, and then optimized through drive tests. With the drive tests information, the operators detect the poorly covered areas and take actions to eliminate them. The introduction of self-organized or “cognitive” ... View full abstract»
