VANET is no exception and poses special challenges in routing techniques. Position based routing protocols are considered to be apt for vehicular networks [1] and to realize that a location service is being used. For a packet to be routed to a destination across the network, the destination's position is to be known in advance. In this paper a new location service paradigm is being proposed to get the destination car's position. An adaptive location update policy is being proposed to maintain up-to-date location information at the location server. The location service uses a density aware server selection policy which selects servers at high density regions of a city. A localized query answering strategy is used for replying to location queries where a server with latest location information replies for a query. The proposed solution is found to be an efficient model for providing location service and ensures a query success ratio of 90.10% at its peak and decreased localization error, at an average of 8m.","PeriodicalId":220290,"journal":{"name":"2011 11th International Conference on ITS Telecommunications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123472927","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}

Distributed GWs in connection with user mobility may result in the need to optimize data routing by GW relocation. It is proposed to include the GWs itself in the decision on GW relocation what is currently done in the control plane node (mobility management entity) only. Proposals are made to allow the relocation also for active mode devices (user activity detection), to detect the occurrence of a non optimal routing situation and to detect situations where a relocation should be suppressed to avoid particularly poor user experience. These improvements are compared with other solutions.","PeriodicalId":220290,"journal":{"name":"2011 11th International Conference on ITS Telecommunications","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129268805","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 paper also illustrates the use of the resulting fuel flow estimates for adaptation and optimization. The fuel flow estimation algorithm functionality differs depending on the powertrain type (gasoline versus diesel, naturally aspirated versus boosted, conventional versus hybrid electric, etc.). To facilitate fuel and time efficient vehicle routing, an adaptation algorithm based on the recursive least squares (Kalman filtering) is defined. This adaptation algorithm learns the expected values and the variances of fuel consumption and travel time from multiple drives of a given vehicle over a given route segment. The use of adaptation from data reduces the need for accurate predictive modeling of vehicle fuel consumption and travel time which depend on difficult to predict and incorporate into the model traffic conditions, topographical road information, weather conditions, and inherently present vehicle-to-vehicle, driver-to-driver and fuel variability. The use of the adaptive models for optimization of vehicle travel is showcased with a simple example of optimizing time of day of departure decisions for a service vehicle. Finally, the use of a large interconnected network of adaptive models for vehicle fleet operation optimization is discussed.","PeriodicalId":220290,"journal":{"name":"2011 11th International Conference on ITS Telecommunications","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129262640","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}

Stereo vision finds many applications in automated systems such robotics, tracking object in 3D space and constructing a 3D spatial model of a scene. There are many human-machine control applications, such vision based remote control system which exploits stereo vision to control the machine in a touch-free environment. In this paper, we present a new stereo vision matching algorithm using an adaptive support window. In many area based algorithms, the selection and computation of the size and shape of the window is the most crucial factor for obtaining high quality disparity map. We developed an adaptive support window based stereo matching using similar color regions selected by the seed growing algorithm. The proposed approach is tested on Middlebury stereo images and results were promising.","PeriodicalId":220290,"journal":{"name":"2011 11th International Conference on ITS Telecommunications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122903513","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 typical VANET defines an intelligent way of using vehicular networking by integrating vehicular connections via a number of short-distance ad-hoc networking links, such as the IEEE802.11p. This type of system could provide effective communication between moving vehicles and fixed Road Side Units (RSUs), which are usually very expensive to install and may, in some cases, undergo heavy demand. To improve the efficiency of communication between vehicles and RSUs (Vehicle to Infrastructure, V2I), most existing work ignores the following facts: the uneven distribution of vehicles and unbalanced working loads on different RSUs. By considering the periodic and the unchanging features of public transportation, we propose a novel V2I hybrid optimisation scheme named Dynamic Resources Allocation Scheme (DRAS). In this scheme, all resources on the RSUs are scheduled as a whole and buses will be introduced as moving infrastructure points (or relay stations) to take some of the burden of the RSUs in real-time traffic conditions. We import the Variable-Length Contention Free Period (VL-CFP) for MAC access and also define Time-to-Live (TTL) value to guarantee the data credibility on bus. Using both Math analysis and NS-2 simulation, we can prove our DRAS can achieve a better QoS performance and adequate utilisation of RSU resources than legacy 802.11p and WAVE-based HCCA. These advantages become more obvious as the vehicles number increases.","PeriodicalId":220290,"journal":{"name":"2011 11th International Conference on ITS Telecommunications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121123100","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}
