This task is particularly challenging because human activities are often performed in not only a simple (i.e., sequential), but also a complex (i.e., interleaved and concurrent) manner in real life. In this paper, we propose a novel Emerging Patterns based approach to Sequential, Interleaved and Concurrent Activity Recognition (epSICAR). We exploit Emerging Patterns as powerful discriminators to differentiate activities. Different from other learning-based models built upon the training dataset for complex activities, we build our activity models by mining a set of Emerging Patterns from the sequential activity trace only and apply these models in recognizing sequential, interleaved and concurrent activities. We conduct our empirical studies in a real smart home, and the evaluation results demonstrate that with a time slice of 15 seconds, we achieve an accuracy of 90.96% for sequential activity, 87.98% for interleaved activity and 78.58% for concurrent activity.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132151319","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}

MiNT-2 is a miniaturized multi-hop wireless network testbed that addresses this challenge by combining the benefits of existing protocol evaluations strategies: simulations and custom built large scale wireless network testbeds. A key component of MiNT-2 is the ability of testbed nodes to move around in the testbed space, whether to reconfigure the network topology or to emulate node mobility patterns. Consequently, we need to devise accurate mechanisms for node localization - the ability of a node to be aware of its exact location in the testbed space. This paper presents the details of the current RFID-based node localization mechanism in MiNT-2. We describe the sources of inaccuracy encountered when using RFID tags due to the error margin associated with the reading range of tags. We then present the implementation and evaluation of two approaches which can be combined to improve the overall accuracy of the RFID-based localization system. Through our experimental evaluation, we show that the proposed approaches improve the accuracy of RFID-based localization mechanisms by up to 58.22% for dense deployment of RFID tags. Though described in the context of the MiNT-2 testbed, our localization techniques are also applicable in more general settings where accurate and inexpensive positioning of mobile nodes is important.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774107","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}

One of the important tasks of middleware in WSN is to support event service. As an important paradigm for event service, publish / subscribe (pub/sub) can support the asynchronous data exchange for applications and has received a lot of attention in traditional distributed systems. In WSNs, however, the design of pub/sub, especially on composite events, has not been adequately addressed. In this paper, we present the design and implementation of PSWare, a pub / sub middleware for WSN which can support both primitive and composite events. Our contribution mainly includes three parts. First, we propose an event definition language (EDL), which is specifically tailored to WSNs and can achieve high expressiveness and availability in the definition of primitive and composite events. The application programmers of PSWare can use the proposed EDL to define events in a simple manner. We implemented a compiler to compile the program written in EDL into byte codes. Second, we develop a runtime environment on sensor nodes, which provide a platform to run the compiled byte codes. Finally, we propose a composite event detection protocol to detect the events in an energy-efficient fashion.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114992606","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, this strategy is extremely inadequate for the increased flexibility of pervasive environments, where users join and leave frequently. Here, users want to discover services dynamically and share them safely taking into account some constraints such as limited computational power and decentralized management. In this paper, we propose a solution to this using a secure resource discovery model. Most of the prior research works on resource discovery assume a constant initial trust value because assignment of initial trust is a critical issue. Even in pervasive smart space, some service sharing may need high security. The level of service security therefore needs to be incorporated in initial trust assignment. In this paper, we present an Adaptive Initial trust and Demand aware Secure Resource Discovery (AID-SRD) model for pervasive environment. We incorporate a Demand Unit in AID-SRD which enables efficient resource sharing with unknown devices. AIDSRD also assigns initial trust considering the variable security need of different services.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115205681","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 investigates organizations for exchanging localized context and surveilling the corresponding areas that minimize bandwidth/energy requirements. We propose a simple model where context is associated with spatial regions, cells, and is transferred to/from mobiles as their trajectories traverse the cells. Key elements of the model are the granularity (e.g., area) of the cells and the amount of context associated with each cell. The model uses random tessellations to generate spatial partitions of the space into cells of varying granularity, and an associated context content function to capture possible ways in which contextual data associated with a cell might scale. We discuss a simple taxonomy for such scalings giving a crude idea of how representative applications might behave. Based on this model we analyze optimal flat aggregative and hierarchical organizations for mediating context exchange revealing some fundamental principles relating the optimal granularity of cells to different types of applications' spatial content scaling.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130732964","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}
