This paper proposes an energy-aware data gathering method called Energy-aware Tree Routing (ETR) in Wireless Sensor Networks. The proposed scheme relates to reliable and energy efficient data routing by selecting a data transmission path in consideration of residual energy at each node to disperse energy consumption across the networks and reliably transmit the data through a detour path when there is link or node failure. Simulation results show that the proposed method outperformed traditional Tree Routing (TR) by 23%∼55% in network lifetime.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122711675","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}

Using appropriate augmentations, the HO can interact faster, safer and easier with the remote real world. In this paper, we present an extension of an existing distributed software and network architecture for collaborative teleoperation based on networked human-scaled mixed reality and mobile platform. The first teleoperation system was composed by a VR application and a Web application. However the 2 systems cannot be used together and it is impossible to control a distant robot simultaneously. Our goal is to update the teleoperation system to permit a heterogeneous collaborative teleoperation between the 2 platforms. An important feature of this interface is based on the use of different Virtual Reality platforms and different Mobile platforms to control one or many robots. The first aim with this work is to develop collaborative robot teaching with the use of virtual or real robot.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122523257","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}

Existing access control approaches such as RBAC, became inappropriate to support this concept because they do not consider human activities. In this paper, we propose Activity-Oriented Access Control (AOAC) model, aiming to support user's activity in ubiquitous environments. We have designed and implemented our initial AOAC system. We also built up a simple scenario in order to illustrate how it supports user activities. The results have shown that AOAC meets our objectives.

In this paper, in order to realize the effective multi-packet access ad-hoc wireless networks, we consider applying multi-input multi-output (MIMO) technique for packet transmission to the next hop node, and we also propose a MAC protocol avoiding the hidden node problem for supporting the multi-packet access with multi-antenna at the nodes around the GW.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114293639","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 cope with inferred problems, such as data redundancy, these systems opt for data-driven content retrieval mechanisms (pull mechanisms). Each node has a list of neighbors with whom it periodically exchanges buffer information and requests content fragments. One of the drawbacks of such a mechanism is that it does not offer intelligent selection of sending neighbors based on their characteristics. This is mainly because the most important criteria used to select nodes is the content availability. This can result in some performance degradation, for instance, due to peers that are sending very small or big parts of the needed data. Resiliency may then be weakened and overhead increased. \u0000 \u0000In this paper we propose to study how the integration of some end nodes characteristics can improve the performance of a typical pull mechanism with random scheduling. We show that the improvement in performance is significant enough despite the fact that the room for improvement is bounded by the limitations of the pull mechanism. Hence we believe that the awareness of end characteristics is an important block upon which we can build more efficient content retrieval mechanisms. The gain in performance can also be amplified by proposing an alternative to the pull mechanism such as a combined pull-push approach.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121894310","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 erasure broadcast channel is considered in which several vehicles are in a cluster and each vehicle attempts to send its own safety message to all other vehicles. A distributed feedback mechanism has been introduced to propagate the network transmission and reception information throughout the network. Based on the feedback information, a packet coding algorithm, inspired by index coding, is proposed to efficiently reduce the number of transmissions and contentions. Simulations show that the proposed protocol yields a greater average probability of successful transmission.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129625074","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}

Unlike traditional client-server applications they do not require central server resources. This makes them less costly to host and maintain. While there have been a large number of P2P applications developed for PC based systems, there are only very few for mobile appliances, such as mobile phones or networked PDAs. Furthermore, there are even fewer applications which operate successfully on the public mobile data network (GPRS, 3G), rather than WiFi. This is largely due to the difficulties posed by the restrictive data access to mobile devices (NATs, Firewalls by the network operators) and traditionally high charges for data communications. Recently, the latter point has been virtually removed by the introduction of flat-rate data packages by the operators. This paper (and demo) present a framework and applications based on a structured P2P overlay network which can successfully operate on the public data network.","PeriodicalId":181188,"journal":{"name":"2009 6th IEEE Consumer Communications and Networking Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129811638","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}
