Radio frequency identification (RFID) is an emerging wireless communication technology which allows objects to be identified automatically. An RFID system consists of a set of readers and several objects, equipped with small and inexpensive computer chips, called tags. In a dense RFID system, where several readers are placed together to improve the read rate and correctness, readers and tags ca...

E-book is a fast growing service for mobile Internet. A user reads e-books through an e-reader that could be a dedicated reading device or a mobile application on the smartphones or the tablets. With content protection of Digital Right Management (DRM), e-books take longer chapter loading time due to necessary data decryption. This paper propose a mechanism that preloads a small number of chapt...

Radio Frequency Identification (RFID) systems, due to recent technological advances, have been used for various advantages in industries like production facilities, supply chain management etc. However, this can require a dense deployment of readers to cover the working area. Without optimizing reader's location and number, many of them can be redundant, reducing the efficiency of the whole RFI...

T echnology advances have made it conceivable to build and deploy dense wireless networks of heterogeneous nodes collecting and disseminating wide ranges of environmental data. An inspired reader can easily imagine a multiplicity of scenarios in which these sensor and actuator networks might excel. The mind-boggling opportunities emerging from this technology indeed give rise to new definitions...

This paper aims to show the effect of macrocellular network densification on the capacity, energy and cost efficiency. The presented results are based on radio propagation simulations that consider macrocellular network with different inter-site distances, i.e. different site densities, and also take into account the presence of indoor receiver points by varying outdoor and indoor receiver dist...
