Recent unprecedented growth in the wireless market has forced network operators to find
new techniques to reduce the operating costs, increase data rates, improve the spectrum …

IEEE 802.15. 4 is a global standard designed for emerging applications in low-rate wireless
personal area networks (LR-WPANs). The standard provides nice features such as a …

We extend the partial inductance concept by replacing the magnetic interaction between
open filaments i and j by that between filament j and a (finite) closed loop, formed by …

This thesis addresses optimization problems in wireless communication networks. An
optimization problem describes a situation in which one wants to find an optimal solution …

Abstract Wireless Sensor Network (WSN) has gained popularity in recent times in
residential, commercial and industrial applications. Several wireless technologies have …

Gathering proper descriptive metadata for multimedia resources is nowadays essential for
effective information processing, recommendation and personalization. And, we still need to …

We propose “mode switch”, an adaptive load-sensitive solution that supports both an energy-
efficient operation mode for transmitting normal sensor data and an QoS-aware low-latency …

Abstract IEEE 802.15. 4 is a global standard designed for emerging applications in low-rate
wireless personal area networks (LR-WPANs). The standard provides beneficial features …

In this paper, we study data gathering in wireless sensor networks where intermediary
nodes perform data aggregation with total fusion. We focus on gathering tree construction …
