This work analyzes a mmWave single-cell network, which comprises a macro base station (BS) and an overlaid tier of small-cell BSs using a wireless backhaul for data traffic. We look for the optimal number of antennas at both BS and small-cell BSs that maximize the energy efficiency (EE) of the system when a hybrid transceiver architecture is employed. Closed-form expressions for the EE-optimal values...
Pervasive computing environment and the Grid infrastructure can be combined to make the computation and information Grid truly ubiquitous. As an emerging field, pervasive grid has not had the opportunity to develop a architecture model similar to the OSI reference model used to describe computer networks. Such a model would be useful in properly classifying design issues and providing needed context...
We address the specification and the formal analysis of systems involving multiple facets. This leads to heterogeneous specifications that cover the different facets of these systems. A method, multifacet specification and analysis, is proposed to master the heterogeneity of systems by considering an abstract reference model that is referred to as a semantic reference for the specific models which...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
