ABSTRACT Images account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, but this is overly restrictive for image data. Our analysis shows that the in-order delivery abstraction provided by a TCP-based approach prevents the receiver application from processing and rendering portions... Continue Reading
Background of the Study Probably no other advancement since the telephone has changed the way humanity works quite as much as the computer. Today powerful computer not larger than a brief -case is on deck around the world they remember information, calculate vital business transaction create forms, draw diagrams and perform a gigabyte of other...

ABSTRACT Voice based xml is the name of a technology standard developed and managed by the Voice based xml Forum (www.voice based xml.org). It builds upon the work of earlier technologies such as VoXML from Motorola and SpeechML from IBM to create a standardized way to interact with services through a voice interface. Not surprisingly, this... Continue Reading
Abstract As a result of the bilingual nature of African nations due to the historical accident of colonialism, the problem of which language (ie. Indigenous or colonial language) to adopt for literary expression, has lingered on. This has precipitated the use of various devices by African writers to contextualize aspects of indigenous meaning in... Continue Reading
ABSTRACT Active networking is the emerging technology that will provide new network environment where lots of potential applications can be enhanced and developed. Current IP network is somehow good at simple packet forwarding, but it desperately needs some flexibility to support QoS and has to meets some restraint in certain environment. Active...

ABSTRACT Images account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, which provides a generic reliable in-order byte-stream abstraction, but which is overly restrictive for image data. We analyze the progression of image quality at the receiver with time, and show that the... Continue Reading
ABSTRACT On-demand routing protocols use route caches to make routing decisions. Due to mobility, cached routes easily become stale. To address the cache staleness issue, prior work in DSR used heuristics with ad hoc parameters to predict the lifetime of a link or a route. However, heuristics cannot accurately estimate timeouts because topology... Continue Reading
ABSTRACT We consider several distributed collaborative key agreement and authentication protocols for dynamic peer groups. There are several important characteristics which make this problem different from traditional secure group communication. They are: 1) distributed nature in which there is no centralized key server; 2) collaborative nature in... Continue Reading
