IEEE 802.11e helps address such QoS requirements, e.g. by prioritising video over background traffic. The reliability problem occurs since it is very challenging (near impossible) for a WLAN protocol to guarantee QoS, especially with uncoordinated contention being the main access mechanism, along with increasing numbers of stations and interfering traffic, with the hostile wireless radio environment making any guarantee foolhardy. With the use of RTP, the video application has some control over end-to-end delay and jitter. Still, in the presence of excessive interference, RTP packet dropping might result in video quality degradation or video outage time. We study the reliability of wireless RTP video streaming over the EDCA MAC protocol, with the ability to forecast (and mitigate the effect of) video failures. Specifically, we introduce a model to evaluate both steady-state and transient video failures due to RTP buffer overflow, the overflow in turn due to WLAN co-channel interference. Quantitative reliability measurements are taken by configuring RTP and EDCA. We evaluate the average packet loss and average outage duration and we validate the theoretical results in an experimental setup. The proposed forecast mechanism could be coupled with and help optimise a) WLAN channel assignment, b) multipath (multi-channel/radio/hop) video routing, and c) adaptive rate control.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122807650","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}

To this goal, we exploit the Compressed Sensing (CS) framework, which provides a new paradigm for recovering signals being sparse in some basis by means of a limited amount of random incoherent projections. In particular, we propose a novel decentralized technique that considers the spatial correlations among the received measurements at the base stations (BSs) to provide global accurate position estimation, while reducing significantly the amount of measurements exchanged among the BSs and required for accurate positioning. We exploit the common structure of the received measurements to design a gossip-based algorithm in order to alleviate the effects of radio channel-induced signal variations on the estimation accuracy. Experimental evaluation with real data demonstrates the superiority of the proposed decentralized CS-based localization technique over traditional fingerprinting methods in terms of the achieved positioning accuracy.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121852746","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}

A link-to-system mapping interface is a mathematical model used in system level and network simulators for accurate prediction of block error rate (BLER) for given signal propagation conditions in order to avoid direct modeling of physical layer processing in the system. The proposed model is based on using mean mutual information per bit (MMIB) between the coded bits and the received logarithms of likelihood ratio (LLR) as a link quality metric. The major feature of the proposed model is the ability to perform fast and accurate BLER prediction for an arbitrary specified code rate and a transport block size, which is especially important for accurate modeling of complex LTE-A system operation. The paper provides the principles of the link-to-system interface design and a full description of the developed model. Verification results for the proposed link-to-system mapping interface are also presented demonstrating the claimed high accuracy of the BLER prediction.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130500501","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, this is a time consuming and challenging task. Therefore, a realistic energy-efficiency evaluation is often neglected or oversimplified by using simple theoretical models or unsuited simulation tools. In this work, we evaluate the energy-efficiency of two specific key exchange protocols, an Elliptic Curve Diffie-Hellman with authentication (ECDH-ECDSA) and a Kerberos based approach, while using different duty-cycling MAC layer protocols. In our evaluation, we compare the results from a theoretical model with simulation results using the AVRORA+ simulation tool and real-world measurements in our WSN testbed SANDbed. Using three MAC layer protocols, TinyOS built in Low-Power-Listening as well as S-MAC and standard 802.15.4, we show that there are several important cross-layer effects that should be considered when performing an energy-efficiency evaluation. Furthermore, we argue, that there are several evaluation metrics like the absolute energy consumption per key exchange or one key exchange per measured time interval.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133249875","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}

While IETF work groups have standardised various mobility management protocols, such as Mobile IPv6 (MIPv6), Fast Handovers for Mobile IPv6 (Predictive FMIPv6, and Reactive FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), Proxy Mobile IPv6 (PMIPv6) and Fast Handovers for PMIPv6 (Predictive FPMIPv6, and Reactive FPMIPv6), the decision regarding which protocol suits the future networks is still a research issue. A good analytical or evaluation model, in terms of various performance metrics like handover latency, packet density, and signalling cost during the handover, is needed to compare various mobility management protocols. In this paper, a novel analytical model in terms of the handover latency, as well as the packet density, and packet arrival rate during the handover time is developed for comparison of various mobility management protocols by applying transport engineering principles in the field of telecommunication. The model enables us to make a few important observations regarding the performance of these mobility management protocols.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134475247","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}
