Heterogeneous wireless networks provide a means to increase network capacity by introducing small cells and adopting a layered architecture. These networks allocate resources flexibly through a combination of time sharing and cell range expansion/contraction allowing a wide range of possible schedulers. In this paper we define capacity of such networks

Throughput Utility Optimization in HetNets
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013The deployment of pico cells to cover traffic hot spots within the footprint of a macro cell provides a powerful approach to meet the massive growth in traffic demands fueled by smartphones and bandwidth-hungry applications. Joint optimization of resource allocation and user association is of critical importance to achieve the maximal capacity benefits

Context-aware handover in HetNets
2014 European Conference on Networks and Communications (EuCNC), 2014In this paper, we focus on the average performance experienced by a mobile user while crossing a pico/femtocell as a function of context parameters, such as user speed, pico/femto cell radius, transmit power of main and subsidiary base stations. The analysis is based on a mathematical model that provides an approximate expression of the average Shannon

RAT selection games in HetNets
2013 Proceedings IEEE INFOCOM, 2013We study the dynamics of network selection in heterogeneous wireless networks (HetNets). Users in such networks selfishly select the best radio access technology (RAT) with the objective of maximizing their own throughputs. We propose two general classes of throughput models that capture the basic properties of random access (e.g., Wi-Fi) and scheduled

Mobility management for D4D in HetNet
2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017Nowadays, cellular operators are facing new challenges to satisfy the future demand of their clients. In addition, user's mobility among multi-tier networks leads to dropping ongoing calls in the system. The introductions of low power nodes and Device-to-Device (D2D) communication into Macro cells are regarded as promising technologies to provide a ...

Software defined access for HetNets
IEEE Communications Magazine, 2016We present software defined access (SDA), an architecture for HetNets that incorporates various elements of SDN and software defined wireless networking (SDWN). SDA introduces a novel logical control path across radio interfaces and up to mobile devices. This control path allows SDA to regulate and configure data path via different RATs. Unlike SDN and

Bandwidth efficient multicast in HetNets
2014 IEEE Global Communications Conference, 2014In this paper, we propose a joint network selection and rate selection scheme for the multicasting in heterogeneous networks, with an aim to minimize the overall bandwidth resources consumed by the multicast stream. We first formulate the scheme as a binary integer programming problem, and then derive a computationally efficient Lagrangian heuristic ...
