Low-profile, compact and easily integrated body worn antennas are the essence of efficient, reliable and user-friendly body-centric networks. The paper presents different planar printed ultra wideband (UWB) antennas and their applications as part of on-body communication systems. Both frequency and time domain characteristics of the proposed antennas are investigated and analysed. The paper emp...

One of the most important aspects for body centric communication is the development of the textile antenna for on-body communication. Antennas for on-body environment usually suffer performance degradation caused by the human body. Apart from that, textile antenna gets easily bent, flexed, wrinkled or wet. This paper presents an investigation on three different designs and types of planar anten...

In the paper, a small antenna for 2.4 GHz body-centric wireless communications is proposed. With the folded ground and U-shaped slot, the antenna has an improved efficiency of 56.5% when it is very close to human body. In addition, the antenna has attractive radiation patterns for body-centric wireless communications.

Wearable devices are transforming computing and the human-computer interaction and they are a primary means for motion recognition of reflexive systems. We review basic wearable deployments and their open wireless communications. An algorithm that uses accelerometer data to provide a control and communication signal is described. Challenges in the further deployment of wearable device in the fi...

This dissertation delves into various aspects of user-centrism in today’s wireless networking landscape. We reconsider the traditional operator/provider-centric view of wireless networking by proposing user-centric solutions to problems along three research dimensions: (i) wireless access, (ii) provision of communication services, and (iii) information collection to be used, among others, for n...

Given the trend towards a user-centric concept in mobile communications, body area networks have received increasing attention within the wireless personal area community. Researchers and designers have been investigating radio propagation characterisation and modelling owing to its importance in developing and designing efficient and reliable radio systems. The paper presents an experimental i...
