Computing and Communications for the Software-Defined Metamaterial Paradigm: A Context Analysis
(2017)
Metamaterials are artificial structures that have recently enabled the realization of novel electromagnetic components with engineered and even unnatural functionalities. Existing metamaterials are specifically designed ...
E-commerce engineering: A short vs long software process for the development of e-commerce applications
(Escola Superior de Tecnologia do Instituto Politecnico de Setubal, 2003)
The immediacy in developing e-commerce applications, the quality of the services offered by these systems band the need for continuous evolution are primary issues that must be fully analysed and understood prior and during ...
Key issues for the design and development of mobile commerce services and applications
(2005)
This paper suggests a new approach for developing m-commerce services and applications based on a scheme that divides m-applications into directory- and transaction-oriented classes, identifies mobile user requirements, ...
Context-aware self-optimization in multiparty converged mobile environments
(2010)
The increase of networking complexity requires the design of new performance optimization schemes for delivering different types of sessions to users under different conditions. In this scope, special attention is given ...
Adaptive optimization for active queue management supporting TCP flows
(Institute of Electrical and Electronics Engineers Inc., 2016)
An adaptive decentralized strategy for active queue management of TCP flows over communication networks is presented. The proposed strategy solves locally, at each link, an optimal control problem, minimizing a cost composed ...
Preserving quality in the development of mobile commerce services and applications
(2005)
Mobile commerce is nowadays a continuously growing area, driving the need for advances in both the network characteristics and infrastructure, as well as in the available mobile devices used. The same need requires the ...
A NEHO based MBMS handover control approach
(2008)
Handover Control is one of the essential means to guarantee the continuity of mobile services to a user traveling in a cellular infrastructure, without interruption. In previous work we illustrated that using the current ...
An enhanced MBMS service provision approach for improved performance in UTRAN
(2011)
As currently specified by 3GPP for UMTS, MBMS services are provided within a cell, either by P-t-P or by P-t-M transmission mode, but not both at the same time. Our previous work highlighted the inefficiencies that can ...
A new approach for efficient MBMS service provision in UTRAN
(2008)
As currently specified by 3GPP, MBMS services can be provided in a cell either by Point-to-Point (PtP) or Point-to-Multipoint (PtM) transmission mode, but not both at the same time. With PtP transmission mode, one Dedicated ...
An enhanced approach for efficient MBMS handovers in 3G networks
(2008)
With MBMS, a mobile Terminal (MT) that is on the move and receive an MBMS service may have to handover from a Common to a Dedicated Channel when crossing the cell's edge. In previous work, we highlighted the possible ...
