The impact of topology changes on the connectivity of an ad hoc wireless network is investigated, where topology changes occur due to node failures. To this end, first, the failure pattern of the static nodes is modeled, then the benefit of having self-organizing capabilities in a wireless network is studied in the presence of several failure patterns. It is shown that the failure pattern of the nodes has a significant impact on the connectivity of the network and having self-organizing capabilities is essential in utilizing wireless networks. Then, the joint impact of an overlaying mobile network and self-organization on the connectivity of a wireless network is studied. The results show that the deployed wireless network can continue to operate even with more than 30% node failure via self-organization and the duty of several failed static nodes can be shared by a very few number of mobile nodes instead of replacing all failed static nodes, extending the network lifetime and improving the utilization of the network significantly.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132079504","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}

Given a statistical model of real-world sensor data and a user's query, the aim of the scheme is to find a sensor selection scheme which best refines the query answer with acceptable confidence. Since most sensor readings are real-valued, we formulate the data acquisition problem as a parametric partially observable Markov decision process (PPOMDP). An existing tool used for solving PPOMDPs, called the fitted value iteration (FVI), is then applied to find a near-optimal sensor selection scheme. Numerical results show that the FVI scheme can achieve near-optimal average long-term rewards, and attain high average confidence levels when compared to other existing algorithms.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133080715","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}

Real-time position localization of moving objects in an indoor environment is an encouraging technology for realizing the vision of creating numerous novel location-aware services and applications in various market segments. An off the shelf development platform that uses Radio Signal Strength Indication (RSSI) based location technique is always used for testing. In this paper we investigated at the affects of polarization on an indoor location tracking system. The target of this paper is to present an optimal design for RSSI location technology. We created a model for determining range form RSSI demonstrated that this model fits our experimental setup. Antenna polarization will affect RSSI and thus range accuracy. The experiments and its errors are carefully analyzed and found that the traditional least squares method of determining the parameters of the range model will give unacceptably high location error. A simple and cheap method of determining polarization angle is introduced with an accelerometer, which also increase the battery life of the node.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130276605","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}

In this paper, a centralized traffic control mechanism is proposed for the evacuation of vehicles that drive toward the dedicated path of the emergency vehicles (EV), e.g. Ambulance, Fire Engines, Police Cars, etc, using the Dedicated Short Range Communications (DSRC) protocol. In our proposed mechanism, a centralized server is used to monitor and control all traffic information to support real time traffic information and services for emergency vehicles, and the centralized server also calculates the shortest path for emergency vehicles to pass by. If the approaching information of emergency vehicles is not announced in advance to other vehicles that will obstruct the approaching path of emergency vehicles, it will cause the traffic muddle on the road and increase the delayed time for emergency vehicles. Thus, we also propose a data dissemination scheme to transmit the warning messages to other vehicles that will obstruct the approaching road of emergency vehicles. In our experiment, we will exhibit the performance of our proposed system.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122944228","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}

Recently, mobile devices are tending to include Global Positioning System and navigation maps. But these research are not sufficient to know about local geometry information. Because if traveler didn't know about detail regional name or local map traveler, hard to estimate it. Recently works suggest some way of building recognition, but these methods militate in favor of recognition because large searching space. And the previous research have restricted to limited space due to restrictive mobile storage. So in this paper we propose optimizing solution for recognition of buildings through optimizing of comparative searching space using Global Positioning System. This efficient database reduction method of building recognition using Global Positioning System can help to find urban area information through building name and information.
