Dynamic Channel Allocation For Mobile Cellular Systems Using A Control Theoretical Approach, Yaya Wei, Chuang Lin, Raad Raad, Fengyuan Ren Jan 2005

Dynamic Channel Allocation For Mobile Cellular Systems Using A Control Theoretical Approach, Yaya Wei, Chuang Lin, Raad Raad, Fengyuan Ren

Faculty of Engineering and Information Sciences - Papers: Part A

The guard channel scheme in wireless mobile networks has attracted and is still drawing research interest owing to easy implementation and flexible control. Dynamic guard channel schemes have already been proposed in the literature to adapt to varying traffic load. This paper presents a novel control-theoretic approach to dynamically reserve guard channels called PI-Guard Channel (PI-GC) controller that maintains the handoff blocking probability (HBP) to a predefined value; while it still improves the channel resource utilization.


A Bluetooth Based Protocol For Multimedia Guidebooks On Mobile Computing Devices, Matthew D'Souza, Adam Postula, Neil Bergmann, Montserrat Ros Jan 2005

A Bluetooth Based Protocol For Multimedia Guidebooks On Mobile Computing Devices, Matthew D'Souza, Adam Postula, Neil Bergmann, Montserrat Ros

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents a Bluetooth based communications protocol used for multimedia guidebooks on mobile computing devices. Multimedia guidebooks are used in museums to allow users to access information about museum exhibits. The multimedia guidebook protocol was successfully implemented on a personal digital assistant and mobile (cell) phone platforms. The protocol overcomes some of the wireless file transfer protocol limitation issues with mobile computing devices. The protocol uses Bluetooth wireless connections as a communications medium. The protocol can be used to transfer various file formats such as image or audio files. The protocol also identifies the language content of the information …


A Bluetooth Wireless Network Infrastructure For Multimedia Guidebooks On Mobile Computing Devices, Matthew D'Souza, Montserrat Ros, Adam Postula, Neil Bergmann Jan 2005

A Bluetooth Wireless Network Infrastructure For Multimedia Guidebooks On Mobile Computing Devices, Matthew D'Souza, Montserrat Ros, Adam Postula, Neil Bergmann

Faculty of Engineering and Information Sciences - Papers: Part A

This paper describes the implementation of a Bluetooth Village Guide Book (VGB) scenario for use in the Kelvin Grove Urban Village located in Brisbane, Australia. An Information Point Station Network (IPSN) was developed, along with software for two types of mobile computing devices. The implementation consists of several Information Point Stations (IPSs) placed at locations of significance, with access to information items on a centralized server. Once registered, the user is given the opportunity to experience context-aware information on demand and in various multimedia formats. These information items are selected by the user, either by way of a menu system …

This paper describes the implementation of a Bluetooth Village Guide Book (VGB) scenario for use in the Kelvin Grove Urban Village located in Brisbane, Australia. An Information Point Station Network (IPSN) was developed, along with software for two types of mobile computing devices. The implementation consists of several Information Point Stations (IPSs) placed at locations of significance, with access to information items on a centralized server. Once a user is registered on the network, he/she is given the opportunity to experience context- (and eventually user-) aware information on demand and in various multimedia formats. These information items are selected by …
