In the method, each pedestrian carries a device which periodically transmits a beacon with a unique ID, and each car passing near the pedestrian receives the beacon by a directional antenna and measures the distance and the angle of arrival. We assume the distribution of the measurement errors to be a normal distribution, and the system calculates the existence probabilities of each pedestrian at each point. By exchanging information of the probabilities between cars, the area with high existence probability is narrowed down. In this paper, we first describe the situations where detecting positions of pedestrians greatly contribute to pedestrian safety, and then we describe the probability model used in our method, the method for calculating existence probabilities from information from multiple cars, and the protocol for exchanging the probability information between cars. We evaluated our method on QualNet simulator, and confirmed that the positions can be detected accurately enough for practical uses.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115060029","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}

Reactive routing protocols like ad hoc on demand distance vector routing (AODV) and dynamic source routing (DSR) are appropriate for mobile environments, because they cope quickly with topological changes. Lately cooperative-transmission-based routing protocols have been proposed to further save energy and enhance reliability. However they require an existing conventional route and individual addressing of the cooperating nodes, which involves a lot of overhead. In this paper, we propose a new opportunistic large array (OLA)-based extension to AODV, which incorporates cooperative diversity into both route discovery and data transmission without requiring any pre-existing route or any individual addressing of relay nodes. An OLA is a form of cooperative diversity in which a group of simple, inexpensive relays or forwarding nodes operate without any mutual coordination, but naturally fire together in response to energy received from a single source or another OLA. Our proposed scheme inherits from OLA lower transmit energy and low computational overhead. However, this paper highlights a newly discovered feature of OLAs, which is robustness against mobility. We show through extensive simulation that this new technique yields significantly longer route lifetimes compared to the traditional AODV scheme, assuming node mobility according to the random waypoint mobility model. We also compare the end-to-end delays of the traditional and proposed schemes. To the best knowledge of the authors, this work is the only unicast, distributed, cooperative ad hoc routing scheme that does not require a pre-existing route.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128556465","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}

The proliferation of devices in the digital home context poses a number of new challenges that makes it necessary to break with the current centralized model for the management of customer networks. We will present ongoing work in this area. The first step was the introduction of standards for the management of remote devices. But it was also necessary to incorporate new paradigms into the model, such as Autonomic Computing, with the deployment of distributed intelligence in home networks that relieves the centralized systems from most of the management tasks. A major challenge is also the encapsulation of all these device ecosystem complexities, providing the upper OSS with simpler interfaces that offer operations at the service level and hide the specificities of device configuration protocols. Moreover, fixed-mobile convergence brings new challenges for the telecommunications industry, who must define new models, systems and processes for an orchestrated configuration of the devices in the home network, regardless of whether they are fixed, mobile or dual.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126321608","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}

Vehicular applications reach from entertainment to traffic information systems, including safety aspects where warning messages can inform drivers about dangerous situations in advance. As performance tests of the real system are very expensive and not comprehensive, today's evaluations are based on analysis and simulation via traffic simulators. In order to investigate the impact of traffic information systems there are two options: First, traffic simulators can be extended by application code and a simplified model for wireless communication. Second, existing network simulators can be coupled with existing traffic simulators. We favor the coupling of existing and well known simulators as we believe that the wireless communication characteristics influence the data transfer significantly and an oversimplified transmission model can lead to flawed results. In this paper we describe the feedback loop between traffic and network simulators named traffic control interface (TraCI) and outline its versatility. We explain its use to determine possible energy consumption reduction when traffic lights send their phase schedules to vehicles.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127254098","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}
