The J2CS system can be classified as a lightweighted, flexible, extensible and component-oriented middleware. In the proposed platform, containers manage the life cycle of components called contextlets which are used to infer high-level events from. low-level sensed data. Containers are also in charge of handling communication details with sensors and other sources of context information. In this paper, we discuss the software architecture, the programming interface, the run-time performance and the implementation of J2CS.

We call such services context-dependent. A context-dependent service needs to monitor the context that affects the execution condition all the time. The proposed method tremendously reduces the cost of context monitoring operations while it surely executes appropriate sendees when their execution conditions are satisfied. Our method assumes that there are a lot of terminals monitoring contexts and a server that collects context information from the terminals to manage sendee executions for a large number of sendees. Each context is modeled by a probabilistic time series, and thus, the probability that an execution condition is satisfied can be calculated at a given time. The time at which the execution condition is likely to be satisfied is anticipated, and the server instructs relevant terminals to monitor contexts and to send their values to it before the anticipated execution. The time to collect context values is decided by the server, which considers the effect of the statistical variance of each context on the probability of satisfying the execution condition. Moreover, each terminal monitors its context and notifies the server when its value is out of the designated range, even if this occurs before the time set by the server. The range of values is set by the server. We conducted simulation experiments that showed the effectiveness of the proposed method","PeriodicalId":377064,"journal":{"name":"2006 ACS/IEEE International Conference on Pervasive Services","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125172443","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}

NS query finds the nearest objects at individual distinct angles from a query point. This query distinguishes itself from other conventional spatial queries such as range queries and nearest neighbor queries by considering both distance and angular aspects of objects with respect to a query point. One of NS query applications is to monitor the nearest objects around an observation point. In our framework, a centralized server is dedicated to collect object location updates, to determine affected NS queries of each object location update, to compute the incremental result change of affected queries and to deliver result updates to corresponding interested users/applications that initiate the queries. In particular, we propose algorithms namely, safe region formation and partial query evaluation, that can significantly improve the system performance. Through simulations, we validate our proposed algorithms over a wide range of settings","PeriodicalId":377064,"journal":{"name":"2006 ACS/IEEE International Conference on Pervasive Services","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133852280","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}

Such autonomous agent could be static, nomadic or highly mobile, and in general, be programmed (rule based) to produce required behaviours by different users. In addition, the communication between these agents may include delays, because of the network, or because their own speed of processing the information. These two characteristics - the rules of behaviour and the temporal delays - could lead the system to display some unwanted periodic behaviour. In this paper we describe our work in progress which includes a framework to study this problem, and a set of initial guidelines to detect this behaviour.

A user may hold on his mobile device his usual documents, and may be able to handle them without the existence of editing softwares. In this article, we aim to reach two goals: (i) handling documents without necessarily using specific softwares and (ii) automatically and spontaneously generating those documents. For that purpose, we rely on service-oriented programming paradigms, especially services deployment and composition capabilities. We propose a platform, called Resurrection, where we consider documents as services incorporating their own handling functions and able to be deployed and executed over a pervasive environment. Our system starts an automatic and spontaneous services documents generation in case of environment proximity. This generation proceeds to documents contents aggregation.

This home link is single point of failure for mobile IPv6. Current specifications of mobile IPv6 does not provide solution to the home link failure problems. In this paper, we introduce \"virtual home link\" as an extension to mobile IPv6. It provides reliability and load balancing among the home links by introducing home link redundancy in the home network. It also provides solution to the home link failure problems. We present the results of several experiments to assess the performance of our solution. The results show that our solution provides transparent and home agent initiated home link failure detection, recovery and load balancing mechanisms. There is a significant reduction in message exchange over the air interface. Also, it provides high service availability in the upper layer applications. The home link failure recovery is fast and efficient. Moreover, there is reduced workload on the mobile node. Finally, the load balancing mechanism of our solution provides efficient, dynamic and transparent load balancing among multiple home links.
