Traditional reliable multicast protocols depend on assumptions about flow control and reliability mechanisms, and they suffer from a kind of interference between these mechanisms. This in turn affects the overall performance, throughput and scalability of group applications utili
Performance Study of OFDM over Multipath Fading Channels for Next Wireless Communications
Orthogonal Frequency Division Multiplexing (OFDM) is a very efficient multicarrier technique. OFDM is used more and more in recent wideband digital communications. It has numerous advantages such as the ability to handle severe channel conditions, efficient spectral usage, reduce
Performance Study of Turbo Code with Interleaver Design
This paper begins with an investigation of the optimization of binary turbo code through good interleaver design. For this purpose, different types of interleaver have designed here and have evaluated their performance. Basically the performances of the turbo code using block int
A Performance Study of An Object - Oriented , ParallelOperating
The nascent and rapidly evolving state of parallel systems often leaves parallel application developers at the mercy of ineecient, innexible operating system software. To assess the feasibility of performance tuning via malleable system software and to understand the performance
A Comprehensive Performance Study of IEEE 802 . 15 . 4
IEEE 802.15.4 is a new standard uniquely designed for low rate wireless personal area networks (LRWPANs). It targets low data rate, low power consumption and low cost wireless networking, and offers device level wireless connectivity. We develop an NS2 simulator for IEEE 802.15.4
A Performance Study of Locking Granularity in Shared-Nothing Parallel Database Systems
Locking granularity refers to the size of a lockable data unit, called a "granule", in a database system. Fine granularity improves system performance by increasing concurrency level but it also increases lock management overhead. Coarse granularity, on the other hand, sacrifices
JXTA Performance Study
—Project JXTA is the first peer-to-peer application development infrastructure that includes standard protocols and multi-language implementations. Performance and scalability of JXTA are not well understood, despite its widespread usage in research and increasing popularity in t
A Multiprocessor System with Non-Preemptive Earliest-Deadline-First Scheduling Policy: A Performability Study
This paper introduces an analytical method for approximating the performability of a firm realtime system modeled by a multi-server queue. The service discipline in the queue is earliestdeadline- first (EDF), which is an optimal scheduling algorithm. Real-time jobs with exponenti
Performance Studies of Multiple-Packet Multistage Cube Networks and Comparison to Circuit Switching
This paper extends the modeling and analysis of packet switched multistage cube intercoimection networks to include the use of multiple-packet message formats. A multiplepacket message format is needed within an interconnection network when the message to be transmitted exceeds t
Performance Study on Audio Codec and Session Transfer of Open Source VoIP applications
Voice over Internet Protocol (VoIP) application or commonly known as softphone has been developing an increasingly large market in today’s telecommunication world and the trend is expected to continue with the enhancement of additional features. This includes leveraging on the ex
