Most work so far has aimed to provide an integration of these networks rather than their co-operation. In the mobile VCE III program, heterogeneous networks remain autonomous, independently-managed entities. In other words, networks are inter-worked and cooperate with each other to provide enriched services to users. The networks are owned by and under the control of their respective operators. The access cores of these networks are inter-connected via a logical interface enabling inter-working at the network and service layers. As part of the mobile VCE Core III program, we focus on mobility management, which is the key issue to support seamless roaming of the mobile users among these heterogeneous networks in an efficient way. In this paper, we consider a group handover scenario from a WLAN to DVB/UMTS network within the network mobility (NEMO) framework","PeriodicalId":299928,"journal":{"name":"MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121993051","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 method proposed, which is compatible with standard IEC 61000-4-7, consists of a two-stage process. In the first stage the fundamental component of the input signal is computed and subtracted from the input signal and, in the second stage the wavelet-packet transform is applied to the resultant signal to compute the rest of harmonic groups in the input signal without the interference of the fundamental component spectral leakage. The results obtained in the application of the method show a good performance in the estimation of the harmonic groups in voltage and current waveforms","PeriodicalId":299928,"journal":{"name":"MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123585885","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}

There are a number of available remote access methods, and a range of point products for providing dialup access, VPNs, Web, Citrix, and wireless access. However, information systems face significant challenges integrating multiple point products and providing a manageable framework for effective access control software. As many types of people need easy access to business-critical information, the challenge is to assure that only the right people have access to the right information. This paper presents various methods and techniques for controlling system resources users' access to ensure that only authorized users can access secured resources.

In network simulator ns2, three packet switch architectures were implemented and combined with UDP and TCP transport. This multilayer model thus combines mechanisms of L1-2 and L4. Additionally, flows with different mean flow size and flow size distribution were applied and the impact transport flow characteristic was analyzed. In particular, the heavy-tail distributed flows were compared to constant flow size. The switching performance measured in terms of packet loss probability and packet delay were analyzed under different traffic loads and buffer sizes. The purpose of the research was thus to understand in more detail a possible impact of new IP traffic patterns (e.g. caused by predominant share of peer-to-peer traffic and corresponding applications) on packet switching systems. The results indicate that the intrinsic characteristics of packet switch architectures reflect in the performance under different transport protocols and flows. The influence of the load or buffer space change is more manageable or predictable, even if we consider the differences among architectures. On the other hand, keeping the same overall load and just replacing the TCP transport with UDP or loading the network with heavy-tail distributed flow sizes or increasing the mean flow size results in more aggressive traffic patterns that may result in a severe deterioration of switching performance","PeriodicalId":299928,"journal":{"name":"MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123685717","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 protection capacity reservation depends on the protection probability of the primary communication, what has been introduced as a design option.

It is observed that the software solution could not easily reach the necessary rates and the hardware solution is applied in order to achieve the required throughput.
