Mobility, quality of service (QoS) support, and multicast routing capability are important requirements for today’s networks. This is a result of the changes in wireless users’ expectations, which favour group-oriented, high-quality, multimedia communication. Ad hoc networks enhanced with QoS multicasting strategies can provide users with these features. This paper defines the building blocks of a

This thesis addresses the problem of global localization from images. The overall goal is to find the location and the direction of a camera given an image taken with the camera relative a 3D world model. In order to solve the problem several subproblems have to be handled. The two main steps for constructing a system for global localization consist of model building and localization. For the mode

This paper is concerned with the impact of technology scaling on the choice of A/D converters in telecom receivers. It is shown that the trend of diminishing feature size, together with better matching of passive components, allows the use of A/D topologies traditionally confined to low-frequency, medium-resolution applications. The design of a 10 bit 20 MS/s ADC using the successive approximation
