The present work is a medium access control protocol for time division-code division multiple access system to distribute the available bandwidth among the mixture of different traffic classes depending upon their quality of service requirement. The proposed scheme is the combination of packet scheduling algorithm and packet allocation algorithm. The packet scheduling is based on the packet loss probability and total traffic waiting for transmission in the system. It maximizes the fairness of the system. It also maintains the packet loss probability of all the users in the environment within a limit. The packet scheduling algorithm varies the receive power threshold per packet slot dynamically in case the system packet loss probability and/or system average delay crosses a threshold. The packet allocation is based on the number of packet slot per frame. The performance of the scheme is evaluated in a cellular environment consisting of large number of cells with active users having different multimedia applications. The proposed scheme outperforms existing schemes in terms of delay, throughput and packet loss probability.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84336228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solution comprises of a protocol with several trusted third parties (TTPs) where there is a possibility of threat to the security. Our protocol unanimously selects one TTP among all TTPs in the SMC architecture that owns the responsibility of all the computation in the system. This TTP is called the master TTP and it is different at different times. The procedure of selecting master TTP could be non-deterministic but it is made deterministic by randomization technique. This ensures that no single TTP controls the entire system all the times. At the same time, this also ensures that no TTP knows where the computation is taking place. This approach is having merit over the other one where only one TTP is given the responsibility to hold entire data of the system. Hence, the chances of corruption can be reduce to negligible when we randomize the selection of one TTP instead of having unknown TTP. Our algorithm works on the concepts of multiple TTP to provide zero-hacking for the entire system owing to the situation that it becomes almost impossible for any party to break the security. Formally it is achieved by imposing high computational complexity on the parties.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85376004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant model considers here is Nomotopsilas second order model, with structure parametric variation. In the present paper we have taken Nomotopsilas second order model as it is valid for high frequencies also, while first order model is restricted to low frequencies. In the present paper, the automated PSO enabled QFT design method is used to synthesize a robust course controller that can undertake the exact amount of plant uncertainty and can ensure a proper trade off between robust stability specifications and tracking performance over the entire range of frequencies. The present work is the continuation of the work done by the first author where controller is synthesized manually with the consideration of same process model. But in this article the PSO technique has been employed to tune the controller automatically that can greatly reduces the computational effort compared to manual graphical techniques. It has also been demonstrated that this methodology not only automates loop-shaping but also improves design quality and, most usefully, improves the quality with a reduced order controller.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73618545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system has been implemented using virtual instrumentation technique and PXI architecture which enhances the productivity and reduce the cost through easy-to-integrate application software and PXI modular hardware. The application software of the system has been developed using LabVIEW-based graphical development environment which enables the user to configure the system for single axis or multi-axis operation. Using the front panel of the application software, multi-axis operation can be configured as free-axis or master-slave axes pairs with safety limits. The PXI architecture used for the system is versatile and meets the specific needs of test and measurement applications by adding an integrated trigger bus and reference clock for multi-board synchronization The system presented in this work is being used at National Wind Tunnel Facility (NWTF), IIT Kanpur to develop various motion control model support systems and test rigs. Few of them include model attitude control beta mechanism, single axis/dual axes turntable motion control systems, multi-axis robotic arm and ram-air parachute attitude control test rigs. The motion control function of these systems is integrated and synchronized with the data acquisition and measurement functions for automated wind tunnel testing. However, motion control system presented in this paper has been configured for automated wind tunnel test applications, but can also be easily configured to perform various motion and position control functions for bio-medical, process control, robotics, and CNC machine applications.","PeriodicalId":22230,"journal":{"name":"TENCON 2008 - 2008 IEEE Region 10 Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77947322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
