When these devices run out of local memory, they require backing up their files in an external storage device, which could restrict the user mobility. This paper presents an Adaptive File Transfer Middleware (AFTM) for mobile applications. This middleware eases the transfer of files between a mobile device and an external storage server by accessing the best wireless connection (WiFi, GPRS/UMTS) available, considering quality and cost of the service. AFTM is also able to use the Multimedia Messaging Service (MMS) as another option for transferring files. A File Backup Service (FBS) was built on top of the AFTM. The FBS will detect when the device ran out of local memory and will automatically send selected files from the mobile device to an external storage server, freeing the mobile storage memory. To decide which files should be backed up, FBS implements several file replacement policies. Results showed that the selection of one replacement policy will be a trade-off between the efficiency of the algorithm and the cost of the wireless service available when a file needs to be backed up.","PeriodicalId":165879,"journal":{"name":"2010 International Conference on Data Communication Networking (DCNET)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130796962","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}

However, even today, the state of the art of commercially available optical core networks is based on mature wavelength switching and routing technologies, which lack a transport and control plane architecture that can support statistical traffic multiplexing with guaranteed Quality of Service (QoS) across a wide range of QoS parameters even if they can support fast reconfiguration at msec time scales. For several years, most research efforts have focused on the concepts of Optical Burst Switching (OBS) and Optical Packet Switching (OPS), which are based on the hybrid use of electronic nodes and optical switches to exploit Time Division Multiplexing (TDM) in order to achieve statistical multiplexing and dynamic resource reservation over optical networks. While burst switching has been experimentally proven as a technically feasible technique, its performance suffers especially under strict requirements for QoS guarantees. In this paper we evaluate the performance gains that can be achieved exploiting statistical multiplexing over a large scale core optical network and we demonstrate the efficiency of the CANON architecture (Clustered Architecture for Nodes in an Optical Network) as a viable alternative to OBS, which can achieve both targets for statistical multiplexing gains and QoS guarantees at the same time.","PeriodicalId":165879,"journal":{"name":"2010 International Conference on Data Communication Networking (DCNET)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123338694","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}

Taking this issue into account, this paper proposes an Enhanced Handover Mechanism (EHM) that can create the reduction of both the required time to scan neighbor Base Stations (BSs) and the number of the MBS session update by firstly selecting a neighbor BS guaranteeing a satisfactory level of Received Signal Strength (RSS) value in the current associated MBS zone as the target BS as many as possible. Simulation results show that the EHM can create the reduction of the handover delay time of both multicast and unicast connections while maintaining a satisfactory RSS value of an MS. As a consequence, enhancement of mobility support for real-time MBS can be achieved while keeping compatibility to IEEE 802.16e systems.","PeriodicalId":165879,"journal":{"name":"2010 International Conference on Data Communication Networking (DCNET)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115011817","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}
