Future wireless networks are expected to support multimedia applications. Wireless links, however, have scarce bandwidth compared to wirelines and should support host mobility. In addition to these characteristics, wireless networks have to deal with bandwidth variability and frequent packet errors due to multi-path fading and shadowing. Thus, providing more suitable wireless service is a great...

Using standard components or modules is vital in product design, development and manufacturing. The current book type catalogues and those, in the form of electronic files together with CAD drawings distributed on disks or via web-based publication systems, can not meet industry requirements for collaborative engineering. Ideally, users could source competitive offers from different vendors and...

Today ATM technology is facing challenges from Integrated Service IP, IP switching, Gigabit IP router and Gigabit Ethernet. Although ATM is approved by ITUT as the standard technology in B-ISDN, its survivability is still in question. Since ATM-UBR (Unspecified Bit Rate) provides no service guarantee and ATM-ABR (Available Bit Rate) is still unattainable for most users, many existing users have...
