The design objectives of HMSS are to guarantee the QoS of multimedia services and minimize the power consumption of energy-sensitive DEVs. By classifying traffics into layers with different priorities, HMSS schedules the traffic layer with high priority preferentially. The order of intra- layer traffics is scheduled to minimize the wakeup times. In addition, a sharing common DEV scheme (SCDS) is proposed to reduce the number of the patches caused by classifying traffics. Simulation results show that HMSS guarantees the QoS requirements of multimedia services in IEEE 802.15.3 HR- WPAN, while the Min-Degree Searching (MDS) Scheme proposed in IEEE 802.15.3 does not consider the QoS requirements at all.","PeriodicalId":166361,"journal":{"name":"2007 4th IEEE Consumer Communications and Networking Conference","volume":"38 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":"125073766","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 employs the mobile phone's strong user identification capabilities such as UIMs, device identifiers or digital certificates to authenticate users over the mobile phone network while services are delivered to their appliances via the Internet. The authentication method is targeted to be used on home appliances such as digital televisions with web browsers which do not have rich interfaces. Therefore it is designed not to require users to enter any user information or to install any hardware and/or software into the appliance. This is achieved by binding a service session on the Internet and mobile network session using a barcode scanner on a mobile phone terminal. The prototype also provides an alternative method for mobile phone terminals which does not have a barcode scanner function to complement user availability.","PeriodicalId":166361,"journal":{"name":"2007 4th IEEE Consumer Communications and Networking Conference","volume":"22 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":"120964142","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}

{"title":"Design of a Mobile Client for the AIDA Auction Service","authors":"A. Amoroso, Daniele Borsaro","doi":"10.1109/CCNC.2007.216","DOIUrl":"https://doi.org/10.1109/CCNC.2007.216","url":null,"abstract":"We show the main characteristics of both the AIDA auction service and a client for that service running on a mobile device. The AIDA system supports responsive and available auction services in a large scale distributed environment, such as the Internet. The AIDA service allows for fast evolving auctions on the In- ternet. In this paper we present the main architectural challenges to implement a mobile client for AIDA. We propose the design of a client that can run on a mobile device, such as a smartphone. Moreover, our system provides the auctioneers with a simple mechanism to switch between computing platforms, such as mobile devices and desktop computers. The auctioneer can switch between several devices as long as those those can exchange a single and small file. I. INTRODUCTION These years the auction services over the Internet are gaining increasing popularity, e.g. WWW.EBAY.COM and WWW.AMAZON.COM. Commonly, the duration of those auc- tions has an order of magnitude of several days. This char- acteristic is a consequence of the asynchronous nature of the Internet, based on a best-effort communication service (1)-(4). Additionally, it seems that the current Internet-based auction services rely, in general, on centralized architectures that are prone to scalability and availability drawbacks. Server's overloading may occur, if an arbitrary large number of users concurrently access the service. In absence, or insufficient, server replication, a failure can halt the system, or deteriorate its performance. The most common Internet auctions, i.e. those that end at a predefined time, exhibit an interesting users behavior, called last-minute bidding (5): the users tend to submit their bid as close as possible to the end of the auction, reducing the probability that someone else might submit a better bid. This phenomenon exacerbates the scalability requirements of the auction system. Owing to the above observations, we proposed an ar- chitecture for supporting auction services over the Internet that is based on replicated services across a number of servers distributed over this network. The architecture, named AIDA (Architecture for Internet-based Distributed Auctions), is based on both hierarchical lightweight communications, and coordinator-cohort computation (6). Our architecture offers advantages with respect to both the auction service provider and to the user. Specifically, from the service provider perspective, our distributed architectures can accommodate an arbitrary number of users by balancing the work load among all the servers implementing the auction service. From the user perspective, our architecture can support a responsive auction service, provided that the client is bound to the \"most responsive\" server, i.e. the server with the lower sum of workload and congested path to the client. Moreover, the auctions implemented with AIDA could be \"fast\", i.e. could have a duration of few minutes. This characteristic is currently uncommon i","PeriodicalId":166361,"journal":{"name":"2007 4th IEEE Consumer Communications and Networking Conference","volume":"8 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":"122489988","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 first stage detects user number and power level of uncoordinated FH signals. Based on knowledge of detected side information from the first stage, the second stage performs SFH/BFSK maximum likelihood detection. When user number and power level of uncoordinated FH signals are unknown, the proposed two-stage detection scheme outperforms existing multilevel FSK conventional detectors and two-user multiuser detectors. In this scenario, simulation results demonstrate a critical role of the first-stage detector in the overall scheme when it provides the above side information. On the other hand, when knowledge of uncoordinated user number and power level is available to the desired user's receiver, simulation results also show superiority of the proposed second- stage detector over equal-gain receivers and self-normalized receivers.","PeriodicalId":166361,"journal":{"name":"2007 4th IEEE Consumer Communications and Networking Conference","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":"130551378","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}

While a few P2P streaming mechanisms have been recently proposed, the behavior of these mechanisms in sessions where a large fraction of uasers are residential peers have not been examined. Several characteristics of residential users could affect the behavior of P2P streaming sessions including (i) the heterogeneity of access link bandwidth, (ii) the limitation of available resources due to asymmetric nature of access link bandwidth (for DSL and cable modem), and (iii) the participation of free-loaders. In this paper, we examine the effect of these three character- istics of residential users on the performance of P2P streaming mechanisms using ns simulations. We show that these character- istics could adversely affect the performance of P2P streaming mechanisms as follows. First, the delivered quality to individual users is not correlated with their contributed resource to the system. Second, the presence of free-loaders could dramatically degrade the delivered quality to participating peers even when the amount of available resources in the system are adequate. Our findings suggest that P2P streaming has to address these issues in order to be successfully deployed among residential users.","PeriodicalId":166361,"journal":{"name":"2007 4th IEEE Consumer Communications and Networking Conference","volume":"3 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":"126442710","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 configuration of antibodies evolves via genetic operations (e.g., mutation and crossover).
