However, such distributed operation of the Medium Access Control (MAC) layer leads to sub-optimal utilization of the shared channel. One of the reasons is the occurrence of collisions when more than one packet is transmitted at the same time. These packets cannot be decoded and retransmissions are necessary. However, it has been recently shown that it is possible to apply signal processing techniques with these collided packets so that useful information can be decoded. This was recently proposed in the Irregular Repetition Slotted ALOHA (IRSA), achieving a throughput T ≃ 0.97 for very large MAC frame lengths as long as the number of active users is smaller than the number of slots per frame. In this paper, we extend the operation of IRSA with i) an iterative physical layer decoding processing that exploits the capture effect and ii) a Successive Interference Cancellation (SIC) processing at the slot-level, named intra-slot SIC, to decode more than one colliding packet per slot. We evaluate the performance of the proposed scheme, referred to as Extended IRSA (E-IRSA), in terms of throughput and channel capacity. Computer-based simulation results show that E-IRSA protocol allows to reach the maximum theoretical achievable throughput even in scenarios where the number of active users is higher than the number of slots per frame. Results also show that E-IRSA protocol significantly improves the performance even for small MAC frame lengths used in practical scenarios.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86772480","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}

Gallium nitride based micro light emitting diodes (μLEDs) are considered as a transmitter unit. A two transmitter and two optical receiver based MIMO setup is used. The performance of OSM-OFDM system is experimentally analysed by varying the semi-angle at half power, θ½ of the μLEDs. The optical cross-talk in the MIMO channel is quantified and its effect on the achievable data rate and bit error rate (BER) performance is analysed. The experimental results show that OSM-OFDM achieves higher data rates than single-input and single-output (SISO)-OFDM for all the ranges of θ½ of the μLEDs under study. However, the BER performance of OSM-OFDM is worse than in the case of SISO-OFDM. The maximum achievable data rate in OSM-OFDM is 1.34 Gb/s and 1.17 Gb/s in SISO-OFDM for θ½ of 2.27° at a link distance of 1 m using adaptive data loading. The experimental results also show that due to the strongly correlated channels, the system performance is highly dependent on the θ½ of the μLEDs.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86990300","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}

We consider a setup where the BS employs Mosc free-running oscillators, and M/Mosc antennas are connected to each oscillator. For this configuration, we analyze the impact of phase noise on the performance of regularized zero-forcing (RZF) precoding, when M and the number of users K are asymptotically large, while the ratio M/K = β is fixed. We analytically show that the impact of phase noise on the signal-to-interference-plus-noise ratio (SINR) can be quantified as an effective reduction in the quality of the channel state information available at the BS when compared to a system without phase noise. As a consequence, we observe that as Mosc increases, the SINR of the RZF precoder degrades as the interference power increases, and the desired signal power decreases. On the other hand, the variance of the random phase variations caused by the BS oscillators reduces with increasing Mosc. Through simulations, we verify our analytical results, and study the performance of the RZF precoder for different phase noise and channel noise variances.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86848866","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 would inevitably enhance the requirements of constructing dynamic and secure end-to-end (E2E)connections among the heterogenous network devices with imbalanced resource profiles and less or no previous knowledge about each other. The device constraints and the dynamic link creations make it challenging to use pre-shared keys for every secure E2E communication scenario in IoT. We propose a proxy-based key establishment protocol for the IoT, which enables any two unknown high resource constrained devices to initiate secure E2E communication. The high constrained devices should be legitimate and maintain secured connections with the neighbouring less constrained devices in the local networks, in which they are deployed. The less constrained devices are performing as the proxies and collaboratively advocate the expensive cryptographic operations during the session key computation. Finally, we demonstrate the applicability of our solution in constrained IoT devices by providing performance and security analysis.","PeriodicalId":6464,"journal":{"name":"2015 IEEE International Conference on Communication Workshop (ICCW)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87045272","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":null,"pages":null},"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}
