Abstract Building upon the existing Universal Description, Discovery and Integration (UDDI) registry specification, this thesis proposes additonal features and specifications to the OASIS standard, UDDI v3.0.2. These improvements and additional capabilities on UDDI make significant steps forward in interoperability with other development frameworks, programming paradigms and registry standards, enhance the search capabilities of UDDI by including support for aggregated searches, reduced bandwidth...

Abstract This thesis presents a method for dyamically setting 802.11 wireless LAN waveforms and transmission power levels based on the wireless channel's signal to noise ratio. Simulation models were developed to study the performance of our media access control (MAC) protocol, SNR-WPA (Signal to Noise Ratio-Waveform Power Adaptation), and compare the performance to a baseline wireless LAN MAC. SNR-WPA method is shown to increase the throughput and range while decreasing the packet delay for...

Abstract Changes in the competitive landscape among telecommunication providers have forced the telecommunications industry to reevaluate its cost and pricing structures. Multimedia services are rapidly gaining in popularity as high-speed data connections become widespread. Enabling the delivery of new multimedia services in a standardized way thereby reducing the cost associated with the introduction of new services is the key to the success of [the] telecommunication industry. This need led to...

Abstract This thesis is the result of work done on extending the capabilities of SOCKS protocol. SOCKS is an application layer network security protocol deployed in firewalls, standardized in Request For Comments (RFC) 1928 by the Internet Engineering Task Force (IETF) as SOCKS Version 5. There are two proposed extensions to the SOCKS protocol made and implemented in this thesis. The first extension is the addition of multicast capabilities to the SOCKS protocol. The current standard of the...

Abstract The IEEE 802.11 standard is becoming the most popular and efficient network topology deployed today. Providing and ensuring the security of wireless network is essential part to its continuous growth. Goals such as confidentiality and trust imply that every data transmitted by each user stays known only to the communicating parties. Authorization of users is also a very important aspect of network integrity. There exist mechanisms defined by the Wi-Fi Protected Access (WPA) protocol that...
