Low Extra Delay Background Transport (LEDBAT) is a delay-based Internet congestion control mechanism developed to allow fair and efficient data transfer when delay-sensitive and file sharing applications co-exist in networks. A LEDBAT source increases its congestion window until a fixed, pre-defined target queue delay is experienced. This paper analyses LEDBAT congestion control showing that the current algorithm, although quickly reaching a steady state (i.e. target delay reached), results in large oscillations of congestion window and queue delay once in steady state. We therefore propose a dynamic calculation of the congestion window gain once in steady state, and show that the proposed modification stabilises the congestion window while still meeting the fairness and efficiency goals of LEDBAT.

An analytical framework is developed to derive the response time and service availability of client/server based SOA and P2P based SOA. The impact on the response time and service availability for varying load conditions and connectivity for both client/server and P2P SOA implementation is studied. It is found that the response time reduces significantly in P2P based SOA depending on network connectivity and service replication factors. Service availability is also found to be much higher in case of P2P based SOA and the gain are enhanced for higher values of load. In our analysis the impacts of search latency and bandwidth penalty resulting from UDDI distribution are not yet considered.

Robots play a major role in flexible manufacturing system (FMS) and the performance measure of a robot is one of the critical issues in the design of robotic work cells. Performance measure and selection of robot for an application is usually done based on experience, intuition and at most using the kinematic considerations like workspace, manipulability, etc. This problem has become more cumbersome in recent years due to increasing complexity, available features, and facilities offered by different robotic products. In the present work a systematic procedure is developed for performance measure of robots based on various attributes. Subsequently, the selection procedure proceeds to select the alternatives in the shortlist by employing different attributes based specification methods. This is an attempt to create exhaustive procedure by identifying maximum possible number of attributes for robot manipulators. The selection procedures are illustrated with example.

Considering the growing development of information at World Wide Web, the users find it difficult to have access to the documents s/he requires. The purpose of this paper is to present a method for making the search by user more systematic and limited using some statistical techniques. For this purpose, we will present a formula by multiple linear regression models in order to model the relation between lexical objects and ontology. Then for stating ideas on a sample document, we count view values in that document, which are conforming to lexical objects in ontology, and next we will form the document vector. With having optimized document value in the formula out of multiple linear regressions, we can predict the degree of angle between the document vector and ontology vector. The closer the angle to zero, the more relation the document has ontology. Experimental Results show the recommended method would be able to distinguish 100% accuracy of this angle.

This paper investigates the effect of real-time visual feedback to enhance user performance in manipulation of 3 discs “Tower Of Hanoi” task by using Microsoft Visual C++ and OpenGL as a graphic library. This study measures the effectiveness of time taken to complete the task between simulation with real-time visual feedback and without feedback. To do this, a group of respondent have been chosen and tested on the “Tower of Hanoi” manipulation task, in which they received real-time visual feedback and without feedback. Result for time to complete the task has been plotted and analyzed. This work also evaluates the best method of real-time visual feedback in simulation task. Respondents have been given different type of visual feedback such as “colour” or “text” feedback and the time to complete the task has been plotted and analyzed. Three different methods have been investigated and the results showed that the shortest time taken to complete the task was obtained through the experiment with text feedback method while the minimum average number of steps to solve the Tower of Hanoi was also achieved via text feedback method.

Roaming across different access technologies permit people to access Internet via heterogeneous wireless networks such as WLAN, WiMAX, GPRS, 3G and Beyond 3G networks. The convergence of heterogeneous wireless access networks with handoff support enable mobile nodes to freely move in and out of any available networks without breaking the connection to the Internet. In this paper, an Adaptive Cross Layer handoff Management for Future Generation Wireless Networks is presented and an efficient approach in optimizing the handoff decision procedure between WLAN and WiMAXnetworks utilizing IEEE 802.21 media independent handover functions (MIHFs) is proposed. This is expected to support seamless mobility while reducing handoff latency and call dropping probability for optimal user experience.
