Cross-Layer Design in 3G Wireless Networks and Beyond
|
The explosive development of internet and wireless communication has made personal communication more convenient. People can use a handy wireless device to transfer different kinds of data such as voice data, text data, and multimedia data. It is obvious that the increasing use of IP based technology would be the trend for the mobile communication services.
Multimedia streaming, video conferencing, and on-line interactive 3D games are expected to attract an increasing number of users in the future. Such bandwidth is not sufficient for these applications and would be the major challenge for wireless networks.
Although the traditional layered protocol stacks have been used for many years, they are not suitable for the next generation wireless network and the mobile system. Due to the time varying transmission of the wireless channel and the dynamic resource requirements of different application, the traditional approach to the mobile multimedia communication is full of challenges to meet the user requirement on performance and efficiency.
Cross-layer design is a new research topic that actively exploits the dependence between different protocol layers to obtain performance gains. We performed a survey and introduced the cross-layer issues in four research categories: application, mobility, QoS, and security.

Development of Adaptive Service-based Systems in Ubiquitous Computing Environments
|
To achieve the goal of ubiquitous computing (ubicomp) - "computing anytime, anywhere", it is necessary that ubicomp software systems can adapt to dynamically changing environments. Such adaptations change the configuration and behavior of ubicomp software systems to provide not only appropriate functionality but also various satisfactory QoS for users, such as timeliness and security. Recent development of service-oriented architecture (SOA) has shown the great potentials of developing adaptive software systems based on SOA. Software systems based on SOA, called service-based systems, can be rapidly composed from services provided by various organizations regardless the differences in the languages and/or platforms used to implement the services, and can be easily reconfigured in runtime to accommodate new requirements. However, how to develop adaptive service-based systems with satisfactory QoS in dynamic environments like ubicomp environments remains largely unknown.
The challenges for the rapid development, deployment and operations of adaptive service-based systems providing satisfactory QoS in ubicomp environments will be presented. Related research, such as autonomic computing and situation awareness, will also be discussed. In particular, our research on Adaptable Situation-aware Secure Service-based (AS3) systems and trustworthy data sharing and management in collaborative ubiquitous computing environments will be presented. Some related issues, such as security and privacy in service discovery and usage of contextual and situation information, and distributed trust management in service-based systems in ubicomp environments will also be discussed.

Ubiquitous Networking: How to make it work?
|
|
Ubiquitous communications require wireless networking and infrastructure network support. The first step is to look at how the different available technologies will integrate and work with each other. One of the next steps is to seek solutions for connecting "ubiquitous devices" to such "integrated and heterogeneous networks". These two steps together form the evolutionary approach towards ubiquitous networking. This talk introduces our currently implemented ubiquitous transmission system for "ubiquitous devices/terminals/handset", called AnyServer which is an intelligent platform to provide the mobile users with smooth QoS connections/communications, synchronization and roaming over the heterogeneous networks (such as 3G/GSM/WiFi, Sensor network and Internet). Based on SIP, AnyServer is open, scalable, and complaint with IEEE/IETF standards. We will particularly introduce the heterogeneous issue when we do the integrations for the various networks to setup/maintain the real-time video/audio connections among the networks, facing the heterogeneous networks. I will particularly introduce the challenging and interesting issues encountered during our research and implementations for the platform for the "live" integration of the networks.

Multimedia Hashes for Ubiquitous Applications
|
Multimedia hash is different from cryptographic hash. Hash turns digital data (including text, image, audio, and video) into a fixed-size binary string. The hash value is a concise representation of the longer message or document from which it was computed. Cryptographic hash functions are used to do message integrity checks and digital signatures in various information security applications, such as authentication and message integrity. Multimedia hash functions can also be used for cryptographic applications for cryptographic purposes. Unfortunately, most of the exist-ing digital signature based schemes remain vulnerable to incidental modifications. Traditional cryptographic hashes are not applicable in the multimedia applications because they are ex-tremely sensitive to the message being hashed.
Multimedia hash function should have the properties that perceptually identical data should have the same hash value with high probability, while perceptually different images should have independent hash values. In addition, the hash function should be secure, so that an attacker cannot predict the hash value of a known data. A multimedia hash function can be used to search and sort a multimedia database, or to select frames in a video sequence for watermark embedding. A few multimedia hash functions have been proposed recently and they are about to be used in practical applications. In this talk, the concept of the multimedia hash, image hash generating al-gorithms, performance of them, and applications of the multimedia hash will be presented. Algo-rithms based on different image descriptors will be evaluated in terms of robustness, computation time, precision and recall for searching applications.
