Many users also publish personal information about their activities, relationships, locations and interests on these sites, seemingly unaware of how these data can be used by other parties. Sites typically attempt to restrict data-sharing to members of a user''s social network, but this is only effective if these social networks cannot be exploited by malicious users. In this paper we perform an experiment in order to assess the vulnerability and privacy awareness of users when engaging in online relations with random unknown users, or those pretending to be a famous character. We find that usually users do not accept random friendship requests, but some aggressively search for celebrities, making a perfect case for spammers to form honeypots using such fake profiles. We present a set of suggestions for enhancing privacy on social networks which could reduce the threats of identity theft in such environments.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122118162","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}

Since this TDMA is the bottleneck in high traffic networks, in this paper we present a new MAC protocol for UWAC ad-hoc networks that applies spatial reuse to improve network throughput. More specifically, in the proposed protocol selected additional nodes can transmit simultaneously to the active TDMA node, thus improving the efficiency of the MAC protocol. By tracking the time-varying network topology, our protocol adaptively optimizes the set of active nodes and overcomes problems of UWAC networks such as the near-far problem, flickering, and formation of islands. We report performance results for both the conventional TDMA protocol and the proposed protocol from a sea trial at the Haifa harbor. The results show that the new protocol greatly increases the availability of nodes to transmit messages, which leads to an improved overall network throughput in high traffic networks.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124855293","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}

Capitalizing on change-point detection theory with unknown parameters, a sequential cumulative sum (CUSUM)-based scheme is developed with an objective to provide quick and accurate detection of PQ event occurrence in real time. The proposed CUSUM-based scheme evaluates the weighted likelihood ratios by exploiting both the instantaneous and the long-term information of the power waveform. It is shown by computer simulations that the proposed CUSUM-based scheme can achieve a significant performance gain over conventional detection schemes.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"13 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126046472","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, the precise mathematical model of trust and thus applications based on trust in e-commerce system has not been satisfactorily established yet. In this paper, we present a probability theoretic framework to quantitatively measure trust as mathematical reasoning and to model the behaviors of consumers and sellers in the e-commerce system based on trust measure. We first summarize properties of trust in Internet users and their social networking. Then we construct the topology of e-commerce system and apply the statistical inference to derive more reliable trust measure. A reliable algorithm, which is robust to malicious behaviors of the sellers, is therefore developed. Via social network learning, distributed decision is proposed to maintain the accuracy of trust estimation and to better against potential malicious behaviors. Simulations demonstrate that our proposed scheme shows good accuracy in estimation of confidence level and retains robust performance facing a number of malicious users in the e-commerce system.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114208402","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 SR technique can be used in the spectrum sensing based on CFD because the CFD method does not need to consider the distribution of the signals received by the secondary users. An improvement of the spectrum sensing performances can be conducted by the proposed method for its satisfaction of the Improvability of Detection via SR Theorem. Numerical results show that the proposed spectrum sensing scheme has better sensing performances than the conventional CFD method.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114226355","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}

Exploiting already available WLAN APs from fast moving vehicles is a challenging and interesting area of research. In this paper, we measure the data rates achievable in a typical drive thru set up. One reason of preferring WLANs over Cellular systems for getting broadband connectivity is that the former promise much higher data rates. This claim, however, is based on WLANs indoor performance. In this paper, we investigate whether sufficiently high data rates are available even when WLANs are used in rapidly changing high and low mobility environments from vehicles on roads. Experiments are conducted for three different NICs to see if the achievable data rates vary with interface cards. Conclusions reached in this work are based on actual experimentation and the obtained results reflect the actual performance of WLANs in vehicular scenarios. Obtained results are verified with statistical tests.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115307405","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}

More precisely, we develop a simulation testbed for analyzing the performance of a CR user with and without spectrum sensing in a three cell scenario. Three different schemes for spectrum sensing are studied. CR users belong to a Cognitive Radio Network (CRN) which is coexisting with a Primary Radio Network (PRN). Both CRN and PRN are CDMA-based. Soft Handoff (HO) and power control are considered for both CRN and PRN. We evaluate the performance of the proposed systems in terms of outage probability, blocking probability, and average data rate of secondary users (SUs). For comparison purposes, together with the three considered schemes with spectrum sensing we also analyze a scheme without spectrum sensing.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121441386","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 Ricean channels, there is a signal-to-noise ratio-dependent critical data rate below which signaling with zero outage is possible. The link will be more reliable the higher this critical data rate is. We present results of spectral efficiency and outage probability from channel sounder measurements of V2V MIMO radio channels in the 5.2 GHz band. Our results show that MIMO channels with higher spatial correlation lead to lower ergodic capacity and a reduced critical data rate. However, for fixed output power the temporal evolution of the ergodic capacity and critical data rate shows that the channel with the strongest line of sight (LoS)component also has the highest capacity.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130095766","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 motivates a substantial redesign of the algorithms and techniques of the underwater data transfer concerning both physical and data link layers, especially concerning the development of underwater acoustic sensor networks. The recent studies of underwater acoustic sensor networks have caused the appearance of a variety of data link and network layers protocols intended to solve particular tasks for various types of networks. In this paper, we present a new media channel access protocol architecture combining two media access algorithms for the transfer of different data types, notably burst data and short instant messages, in order to provide the network layer with additional capabilities to solve problems in a wider range.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131287474","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}
