However, multipath propagations in radio channels usually result in the angular spread of signal power, which causes interference among the sectors. Moreover, the random movement of the nodes leads to the variation of the interference. An accurate and mathematically tractable packet-level channel model is a key issue to evaluate the capacity and performance of the spatial multiplexing networks. In this paper, we have considered an indoor mobile ad hoc network where the sink node is equipped with an antenna array for beamforming. First, based on the angular power spectral density (APSD) of the indoor channels obtained by our field measurements, the interference among two nodes is evaluated. Second, by assuming two-dimensional random walk of the network nodes, a finite state Markov chain (FSMC) model is proposed to present the random variation of the signal-to-interference ratio (SIR) of the directional links from the nodes to the sink. The closed-form expressions of the state transition probabilities and steady state distributions are derived. Simulation results are also presented to demonstrate the channel evolution process. The proposed packet-level channel model can be conveniently incorporated into analytical frameworks and fast simulations of upper-layer network protocols.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":"48 1","pages":"549-554"},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76231402","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, available measurement techniques that adopt a full reference model (FR) are impractical in real-time transmission scenarios since they require the original video sequence available at the receiver's end. Hence, no-reference (NR) models fill this gap by providing less accurate measurement but sufficiently reliable for real-time video streaming. In this paper, we propose and evaluate a hybrid no-reference prediction model for the perceptual quality of video in the wireless domain. The model is based on fuzzy inference systems (FIS), and exploits several key parameters from both the application layer and physical layer. Hence the model is realized by means of mapping quality of service to quality of experience (QoS/QoE). The model is evaluated in contrast to random neural networks (RNN), and simulation results show considerable prediction accuracy of the model with a correlation coefficient of 92.17% and 0.1098 root mean square error.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":"129 1","pages":"1723-1728"},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76275250","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 that the cloud is very likely to be outside of the trust domain of the users, serious concerns over the confidentiality of the outsourced data are arising. Traditional encryption methods guarantee data confidentiality, but also limit the functionality of the cloud storage as few operations are supported over encrypted data. The main technique contribution of this paper is that we present an efficient data forwarding scheme for the erasure-coded and encrypted cloud, which enforces the cloud not only provide data reliability and confidentiality, but also support the functionality that the encrypted data can be forwarded to another user without being retrieved back. Specifically, we design an all-or-nothing transform based encryption and a variant of ElGamal-based proxy re-encryption algorithms, blending them with the Reed-Solomon erasure code, our scheme is quite more efficient compared with previous studies and only needs to update partial data blocks instead of the whole file for data forwarding. In addition, our scheme also satisfies another practical property that the original data owner can no longer decrypt or forward the re-encrypted data again to other users after a complete data forwarding, which is termed to be “original inaccessibility” in our study. Analysis shows that our scheme is secure and satisfactory. Finally we theoretically and experimentally evaluate the performance of our scheme and the results indicate that our scheme is efficient in the procedure of file dispersal, forward and retrieval.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":"460 1","pages":"1820-1826"},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77728970","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 mapping, however, cannot be selected arbitrarily. Together with the signals from the other network relays, it has to allow the destinations to be able to recover the source data from the available observations. Moreover the mapping should optimize a local relay utility function. This task can be easily solved in centralized networks. In decentralized ones, such as sensor or smart metering networks, a mapping assignment should be derived from mutual node communication, cooperation and/or signaling. In this paper we focus on the practical hardware implementation of such a distributed algorithm called a Distributed Learning Algorithm (DLA). In a two source, two relay and two destination network scenario we have implemented a non-cooperative game-based process that selects the WPLNC mapping of each individual relay node guaranteeing invertibility of WPLNC at the destinations as well as optimizing the relay's utility function, namely the output modulation cardinality. The implementation testbed is based on Software Defined Radio (SDR) modules and it is used to verify the algorithm properties in real-world conditions.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":"29 1","pages":"2127-2132"},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80067704","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}
