But it is still not the optimal way of interaction as one has to be very active updating profiles. With the easy access to mobile devices, modern technologies have now started to adopt to new ways of socialising. mobile devices accompany their users almost all the time, they can record and observe their users behavior as well as gather information about their social circle. Therefore, they can help users to get information from contacts, that they probably not even know. In this paper we put our efforts towards the initial design of an architecture that will sniff for information around the user's surrounding, leveraging useful answers on their demand.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132413603","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}

Users and service providers are slowly and steadily switching to PDAs and cell-phones for electronic commerce transactions. The key factor is security of the information such as password that is used for authentication. Besides, all identification related information follow the first authentication step. We propose a simple, yet elegant method called Mobile PassPattern System (MPPS) to solve the authentication problem in a ubiquitous manner. We have shown that MPPS withstands all known attacks relevant to this mode of authentication.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125196667","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}

Besides the problems of hidden terminal and exposed terminal, there is also unreachability problem, which may result in link/routing failures and unfairness among multiple traffic flows. In this paper, a novel medium access control (MAC) protocol, called eMAC, is proposed. Under the proposed scheme, stations maintain double hop neighborhood (DHN) graphs while exchanging designated eMAC tables to share their knowledge about their neighbourhood topology. Using a DHN graph and an adaptive unreachability reporting mechanism, stations are reliably informed about their neighbours' unreachability status; therefore, they avoid establishing link layer connections with their unreachable neighbours and consequently, network resources are not consumed for unsuccessful connection establishment efforts. Furthermore, we propose an adaptive table broadcasting technique to facilitate topology information dissemination in mobile ad hoc networks. Performance of the proposed schemes is evaluated and compared with earlier schemes through simulations.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114575096","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}

Additionally, we run experiments in an indoor testbed to verify the performance of our ETT plug-in. Our results show that the ETT metric has the lowest packet loss rate and the lowest round trip time among the analyzed metrics, because it reproduces link quality conditions and also takes into account physical transmission rates.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131665898","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}

In this paper we propose an algorithm to optimize the MPR-based flooding by using network coding where MPR nodes do not simply forward packets they overhear but may send out information that is coded over the contents of several packets they received. Our interest is to reduce the number of transmissions. We show by simulation that flooding can be efficiently performed by exploiting network coding with multipoint relays, resulting in significant reductions in the number of transmissions in the network. We can get benefits from this approach also in other practical considerations such as restricted complexity and memory capabilities.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125553602","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}

This paper reveals the potential for energy saving in future home environments, which can be achieved by sharing resources, and concentrating 24/7 computation on a small number of PCs. We present three evaluation methods for assessing the expected performance. A newly created prototype is able to interconnect an arbitrary number of homes by using the free P2P library FreePastry. The prototype is able to carry out task virtualization by sending virtual machines (VMs) from one home to another, most VMs being of size around 4 MB. We present measurement results from the prototype. We then describe a general model for download sharing, and compare performance results from an analytical model to results obtained from a discrete event simulator. The simulation results demonstrate that it is possible to reach almost optimal energy efficiency for this scenario.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617827","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}

Streaming technique, widely developed and used in the internet to convey multimedia application (e.g., audio, video clip, etc.), is supposed to occupy a large share of bandwidth in future wireless systems (e.g. WiMAX, LTE ldquoLong Term Evolutionrdquo, etc.). The stringent QoS constraints of these services may be reached at the expense of the system capacity and therefore a trade off between Fairness and capacity should be achieved. The novel opportunistic scheduler proposed in this paper balances this trade off and allows thus OFDMA systems to handle streaming services without losing much cell capacity. Results afforded by this scheduler are promising and show that it outperforms the existing scheduling algorithms.","PeriodicalId":247938,"journal":{"name":"2008 1st IFIP Wireless Days","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125245865","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}
