The desire for ubiquitous access to information and the Internet while on the move characterizes an entirely new computing paradigm, leading to wireless mobile computing. This emerging field has the potential to dramatically change the society as users become untethered from information sources and communication media. The driving forces include the tremendous advent of wireless access technologies and systems such as GSM/GPRS, cdma2000, WCDMA, UMTS, wireless LANs, as well as the wide availability of low-cost, hand-held devices like laptops, palmtops, pocket PCs, and PDAs.
Emerging applications and services over next generation wireless systems and mobile Internet include news-on-demand, video-on-demand, web browsing, traveler information and location-based services, emergency response, security, pervasive computing, health monitoring, and telemedicine services, to name a few. However, supporting seamless roaming capability (commonly known as mobility management problem) across a multitude of wireless access networks is an extremely challenging task. Furthermore, radio resource (e.g., bandwidth) management and quality-of-service (QoS) provisioning for wireless data networking and multimedia services also offer significant challenges.
This tutorial aims at providing a guided tour of the emerging solutions for mobility management, resource management, wireless data networking, call admission control and QoS provsioning in next generation mobile systems. Also will be discussed open research problems and issues on this topic.
