In MIPv6, home agent acts as the anchor points of mobile nodes and is responsible for receiving data packets on behalf of them and tunneling the packets to the current points of attachment of the mobile nodes in the Internet. Two problems existing in the current MIPv6 scheme motivate the study of this paper. First, we do not have any proper load sharing mechanism for multiple HA deployment. Second, Home Agent failure detection in MIPv6 is very slow and there is no specified failure recovery mechanism. In this paper we propose a mechanism to address the above mentioned problems of load sharing and failure recovery while trying to reduce the time of home agent failure detection and recovery. We presented simulation results to demonstrate that our solution can fairly distribute loads among multiple home agents","PeriodicalId":238541,"journal":{"name":"2006 International Conference on Emerging Technologies","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115273281","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}

By supporting existing Ethernet traffic, scheduler avoids the need to redefine QoS parameters for wireless channel. Real time traffic uses fair-queuing model, non real time data use weighted round robin with re-circulating queue to accommodate wireless link error. Best effort traffic use FIFO mechanism.

For this purpose we suggested the parallel shadow image server (PSIS) copying techniques in parallel to the resource manager for having the check points for rescheduling of jobs from the nearest flag, if in case the fault is detected. The job process is to be scheduled from the resource manager node to the worker nodes and then its' submitted back by the worker nodes in serialized form to the parallel shadow image servers from the worker nodes after the pre-specified amount of time, which we call the recent spawn or the flag check point for rescheduling or reprocessing of job.

Its system capacity is found to be function of DS code length, number of hopping frequencies, signal to noise ratio and acceptable probability of error.

However, the performance of RoF systems can be severely degraded due to nonlinear effects in the channel. Also, orthogonal frequency division multiplexing (OFDM), as a standard for broadband wireless networks, is being proposed for deployment with RoF systems to facilitate the total performance of a system. In this research, at first, the performance of OFDM-based RoF link with Mach-Zehnder modulator distortion effects has been analyzed at 5.8 GHz. Evaluation of mean-squared error of the proposed OFDM-RoF system was carried out to compare with the conventional single carrier system based RoF link after the modulator distortion case and also for fixed signal to noise ratio (SNR) of 20 dB using undistorted OFDM signal. Later, nominal and offset biasing pre-distortion techniques are applied in proposed system to linearize the OFDM-RoF link. Thus, finally a comparison between the aforementioned pre-distortion techniques applied showed important observation in terms of distortion-free dynamic range and SNR to choose offset predistortion technique for our proposed system","PeriodicalId":238541,"journal":{"name":"2006 International Conference on Emerging Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128406968","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}
