Cloud service providers leverage virtualization technology to multiplex hardware resource, consolidate servers, and provide a rounded executing environment to remote cloud users. However, the current executing environment the cloud provides is not trustable. For a user's computing environment faces threats from other malicious cloud users who aim at attacking the whole underlying virtualization software (virtual machine monitor, VMM, or hypervisor). In this paper, we make an analysis of the potential threat to a commodity hyper-visor, and propose architecture for safe executing environment on hardware-sharing platform. The main ideas of our architecture are: removal of interaction between hypervisor and executing environment; attestation of the initial environment state to remote user. To prove the effectiveness of our architecture, we build a prototype system which can create multiple secure isolated executing environment on current multi-core x86 hardware. The final evaluation shows that with current commodity virtualization techniques, we can provide a safe executing environment for remote cloud users with no performance overhead.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124608535","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}

Up to now, many RFID authentication protocols conforming to EPC-C1G2 have been proposed. In 2010, Lo and Yeh proposed an EPC-C1G2 RFID authentication protocol, and employed a formal logic proof to prove the security of their protocol. Herein, we show that Lo-Yeh's protocol is vulnerable to an EPC cracking attack, a location tracking attack, and two impersonation attacks. To improve the security of EPC-C1G2 without incurring much extra cost and overhead, we propose an extended version of EPC-C1G2, called EPC-C1G2*, which only employs stronger CRC and PRNG functions. And then, we propose an improved RFID authentication protocol conforming to EPC-C1G2*, and show that our improved protocol has better security.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129508400","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, in the presence of asymmetric information between the source and potential relay nodes, the relay communication becomes an issue of great concern. To resolve the matter incurred by the existence of asymmetric information, the intrinsic availability of the relay-destination channel state information at the relay node can be exploited. In such case, the source node as an uninformed party not just stimulates relays to participate in cooperative communication, but also incites relays to reveal their channel state information in a trustworthy manner. In this paper, the problem of cooperation incentives under the existence of asymmetric information is studied. The principle of contract theory is applied to cooperative communication and an incentive compatible and individually rational contract is proposed to relay nodes. The designed contract consists of a set of power-credit pairs and offers credit to relays as a reward for participation. To evaluate the accuracy of the proposed scheme, a network system under two different information scenarios is simulated and the effects of the information asymmetry on its performance and sustainability are discussed.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127384333","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 spectrum allocation problem of the femtocell network is challenging for the wireless operator, since the added femtocell tier either requires additional spectrum resource or brings interference to the existing cellular network. In this paper, we consider the methods of spectrum allocation and spectrum sharing to improve the capacity performance of femtocell networks. We first propose a spectrum allocation strategy that utilizes the structure of the cellular network to reduce interference. Then, we propose a spectrum sharing scheme that deals with the problem of insufficient channels for femtocells. Adjacent femtocells could coordinate with each other for resource allocation by taking the instantaneous traffic demand into consideration. Finally, the proposed spectrum management methods are compared with several conventional methods and the improvements of the proposed schemes are verified by simulation results.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129066830","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 market has been flooded with high end consumer electronics using wireless sensor technology. However, most of the current technologies require the sensor to be in the vicinity of the end-user application. There has been some study in the techniques for sensor provisioning and sharing for the large number of existing Wireless Sensor Networks. Virtualization of Wireless Sensor Networks (WSNs) is a step forward in exposing these WSNs to large user base from remote locations. However, there is still a huge gap in bringing together information available from heterogeneous, distributed resources of Wireless Sensor Networks to a non-localized user. In this work, we utilize IaaS paradigm of Cloud Computing in virtualization of sensor networks which gives the flexibility of handling heterogeneous systems. The system also enables a smart device user to access information generated by Wireless Sensors through the cloud via SaaS based design. This allows the system to take common computational tasks to be hosted as a service through the cloud. It frees the smart device user from running heavy applications for data processing and storing. Thus, system provides the smart device user a Cloud Enabled Wireless Sensor Network infrastructure. The system architecture provides the necessary features for it to be scalable and flexible, ensuring reliable sensor data transfer and processing through cloud infrastructure. We also present a small test bed implementation of the system.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"28 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130986659","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 context, cognitive radio has emerged as a breakthrough for effective utilization of radio spectrum. In order to realize dynamic spectrum management in the future, it is imperative to possess a thorough understanding about how wireless spectrum behaves over time, frequency, and space, etc. In this paper, we report the spectrum occupancy measurement campaign conducted in the frequency range of 20-3000MHz based on the radio monitoring network in Yunnan Province. Spectrum occupancy with space and time dependent characteristic at six typical fixed stations are obtained. The measurement results show relatively low spectrum occupancy with great potential for dynamic usage of spectrum. Besides, the ambient noise has a great influence on the measurement results, thus its calibration is a key issue in radio monitoring which is based on energy detection.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126370775","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}

An auction-based algorithm, VCG auction, is proposed to ensure femtocell users submit their utilities truthfully despite the selfish nature of them, so that the resource allocation scheme works efficiently and fairly. We investigate the uplink transmission in a sparsely deployed scenario of Femto-network. By introducing the VCG auction mechanism, an optimum resource allocation scheme is obtained to enhance each femtocell user and the whole macrocell network's revenue both. Anyone who lie about his information will be penalized by extremely high payment and his revenues will decrease a lot. So, the users would rather tell the truth to obtain maximal revenue.

However, these wireless technologies suffer from signal distortion and short Non-Line-Of-Sight (NLOS). Furthermore, in underground disaster it is difficult to transmit sensing data to the ground via wireless signals. In this paper, we study beamforming based signal strengthening scheme in underground wireless sensor networks. Compare with traditional wireless signals, we use acoustic signal, which has several merits: first, it has much longer wavelength, which results to slower decay and longer propagation distance; second, it is resistant to signal distortion, which may help enhance the robustness of the underground monitoring system. Theoretical analysis is provided on both systematic and stochastic errors. Extensive simulations are carried out for theoretical verification.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121109956","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}
