Mobile Intelligence

22.1 INTRODUCTION

In recent years, wearable computing and ubiquitous computing system environment have realized due to the rapid progress of computing and communication technology. Wearable computing system can be broadly defined as mobile electronic devices that can be unobtrusively embedded as part of garment or accessory [2]. Unlike conventional mobile devices, it is always active and running without user's attention and gives services to a user with the support of ubiquitous environment. In the ubiquitous environment, using the wearable computer, we get necessary information anytime and anywhere with a minimal constraint.

In a wearable computer, the design of new paradigm has concentrated on the problems that arises when user has to put up with considerable inconvenience carrying around devices [3–6]. The success of wearable computer will heavily rely on good wearability, usability, aesthetic appearance, and social acceptance. In addition, not merely considering about these uncomfortable carrying issues, the reflection about the exploit of ubiquitous computing environment should be done. The emerging wearable ubiquitous computer should have various communication interfaces, such as WLAN, Bluetooth, and ZigBee communication to support various ubiquitous network environment.

When these various communication interfaces are integrated and used in one converged device, these heterogeneous communication interfaces may interfere with each other because these are usually operated in ...
