Short (smaller-than-5-minutes) sessions are never used or characterized in these analyses as they are unrelated to user behavior and considered as artifacts introduced by the wireless network. In this paper we characterize short 802.11 sessions as recorded through RADIUS authentication. We show that 50% of access points have 70% of smaller than 5 minutes sessions in a 5 months trace from the Eduroam academic wireless network in the University of Porto. Exactly because they are artifacts introduced by the network, short sessions are an important indicator for network management and the quality of the wireless access. Network managers typically do not collect and process session information but rely on SNMP to provide summaries of 802.11 usage data. We develop a modeling framework to provide predictions for the number of short sessions from SNMP data. We model the data stream of each access point using two methods of regression and one classification technique. We evaluate these models based on short session prediction accuracy. The models are trained on the 5 months data and the best results show prediction accuracy of 95.27% in polynomial regression at degree of 3.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132664812","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, RFID tags share a wireless communication medium to deliver their information to the RFID reader which results in tag collisions and, hence, a significant energy consumption and delay in the interrogation process. Handling tag collisions is a challenging task because of the limited capabilities available to passive RFID tags. In classical anti-collision schemes, the RFID reader interrogates all tags in its range at once using its maximum transmission range, which results in many collisions and wastes energy. In a previous work, we proposed a novel approach in which the interrogation zone of an RFID reader is divided into a number of ring-shaped clusters, and tags of different clusters are read separately. We also proposed a method that finds the optimal clustering scheme assuming an ideal setting in which the transmission range of the RFID reader can be tuned with high precision. In this paper, we consider a more practical scenario in which the RFID reader has a finite set of discrete transmission ranges rather than continuous ones. This suits currently existing commercial RFID readers that come with configurable output power. We present a delay mathematical analysis for this optimization problem and devise an algorithm that finds the optimal clustering efficiently. The proposed approach can be integrated with any existing anti-collision scheme to improve its performance and, hence, meet the demand of large scale RFID applications. Simulation results show that our approach is able to make significant improvements in saving energy and time by reducing collisions.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130324869","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 paper proposes two on-demand multipath routing protocols. Efficient, Stable, Disjoint Multipath Routing protocol (ESDMR) and Efficient, Disjoint Multipath Routing protocol (EDMR), the main goal of the proposed routing protocols is to reduce the influence of interference between the selected node-disjoint multipath scheme, by selecting a node-disjoint routes with the minimal interference between them. In addition, both of the proposed protocols used a new proposed technique that aims to reduce the control packets overhead, while it enables the destination node of collecting the required information. Simulation results show that the proposed routing protocols have a higher delivery rate and higher throughput compared with the ones in Split multipath routing protocol (SMR). The significant improvement in packet delivery ratio resulted mainly from reducing the impact of hidden terminal problem. While, increasing the number of available channels between the selected disjoint routes is the main reason for the dramatic improvement in throughput. The efficiency of the proposed protocols and SMR protocol is evaluated by GloMoSim simulator.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123307194","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}

At the same time, location privacy has become one of the most critical concerns for ensuring users' right to protection. Despite the fact that one of the best ways to protect the location information is not to reveal it, there are advantages on using this information to personalize services, however it is necessary to guarantee its protection. Private Information Retrieval is a technique that creates a common language between users and service provider so that external actors cannot understand most of the information being transferred. This paper introduces MaPIR, a mapping-based private information retrieval technique that uses mathematically generated mapping to create redundancy in order to provide multiple answers to a user with an undistinguishable location. This technique is decentralized and focuses on Point of Interest Search-based application, not on tracking services. For performance evaluation, were compared in two scenarios MaPIR, a regular spatial query and the Dummy Query technique, the results show that MaPIR takes only half the time of regular geographical queries on database processing, and 5 times less than the Dummy Query technique, while providing a similar level of redundancy.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116188437","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}

These technologies can potentially play an important role in improving the socioeconomic status of rural areas. However, adaptation of these technologies for provision of relevant multimedia services faces major challenges. Perhaps, Quality of Service (QoS) issues still tops the list of such challenges. In this work we study how to evaluate the QoS of cellular-based systems focusing on an application perspective. We quantify the QoS levels for different traffic models using application and network related parameters to identify the most suitable configuration for running multimedia-based services. More specifically, our analysis is based on considering a unified measure combining key QoS metrics such as packet loss, and delay. For evaluation purposes, we also investigate the QoS issues of deploying a distance education platform running over UMTS cellular systems. The QoS issues related to the deployment of multimedia services in cellular technologies are then considered and analyzed in detail through simulation studies. The results show that by inclusion of the communication technology and application related parameters along with the number of users in QoS evaluations, better performing network configurations can be readily selected. This is achieved, through our proposed application-based QoS evaluation scheme that is based on combining various related measures. The proposed scheme is shown to be particularly beneficial for evaluating and improving QoS for multimedia-based heterogeneous networks.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121230643","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, when it comes to quality of service (QoS), WLAN has lower reliability, where it has higher latency and packet-loss, especially for real-time streaming applications such as voice over internet protocol (VoIP) and multimedia. Thus, improving QoS in WLAN is a major research challenge, where packet-loss is considered most critical while other factors, such as latency and jitter are acceptable to certain level of tolerance. Theoretically WLAN can provide higher bandwidth and lower latency; however, practical results disagree with this statement. In this paper, we investigated the dilemma using different combination of wireless devices within a local area network to identify the problem. We propose an infrastructure based scheme to improve the QoS for real-time traffic over WLAN. We setup a wireless network using different types of wireless devices and tested VoIP traffic over it. Our simulation results for G.729.2 codec on IPv4 and IPv6 using virtual access point (v-AP) showed better performance than physical access point (ph-AP). We also observed that usage of different wireless devices within a network highly reduced real-time application performance.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122715928","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}
