Considerable emphasis in scientific computing (SC) software development has been placed on the software qualities of performance and correctness. However, other software qualities have received less attention, such as the qualities of usability, maintainability, testability and reusability. Presented in this book is a survey titled "Survey on Developing Scientific Computing Software," which is apparently the first conducted to explore the current approaches to SC software development and to determine which qualities of SC software are in most need of improvement. In terms of the problems in...

IP-based multimedia communications have become increasingly popular in recent years. With the increasing coverage of the IEEE 802:11(TM) based wireless networks, IP-based multimedia communications over wireless networks are also drawing extensive attention in both academia and industry. Due to the openness and distributed nature of the protocols involved, such as the session initiation protocol (SIP) and the IEEE 802:11(TM) standard, it becomes easy for malicious users in the network to achieve their own gain or disrupt the service by deviating from the normal protocol behaviors. This...
