Many researchers have investigated the development of such learning environments; nevertheless, the criteria of establishing a u-learning environment have not been clearly defined, not to mention the strategies for conducting effective learning activities. To cope with these problems, we shall present in this paper the basic criteria of constructing a u-learning environment, such that subsequent researchers can identify and check the necessary items while establishing the learning environment. Moreover, several strategies for conducting u-learning activities are proposed, based on the given criteria","PeriodicalId":418337,"journal":{"name":"IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (SUTC'06)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117047768","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}

Though existing sleep scheduling algorithms save energy, they lead to a large increase in end-to-end latency. We propose a new sleep schedule (Q-MAC) for query based sensor networks that provides minimum end-to-end latency with energy efficient data transmission. Whenever there is no query, the radios of the nodes sleep more using a static schedule. Whenever a query is initiated, the sleep schedule is changed dynamically. Based on the destination's location and packet transmission time, we predict the data arrival time and retain the radio of a particular node, which has forwarded the query packet, in the active state until the data packets are forwarded. Since our dynamic schedule alters the active period of the intermediate nodes in advance by predicting the packet arrival time, data is transmitted to the sink with low end-to-end latency. The objectives of our protocol are to (1) minimize the end-to-end latency by alerting the intermediate nodes in advance using the dynamic schedule (2) reduce energy consumption by activating the neighbor nodes only when packets (query and data) are transmitted. Simulation results show that Q-MAC performs better than S-MAC by reducing the latency up to 80% with minimum energy consumption","PeriodicalId":418337,"journal":{"name":"IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (SUTC'06)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115088048","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, trust establishment is not well understood. Different researchers have focused on different aspects of trust establishment. In this paper, we provide a unifying view of trust establishment, which includes the primitives, authentication, semantics of trust and trust evaluation. We propose a model which can serve as a framework for trust establishment. Trust is justified only if its establishment is secure against an adversary who seeks to gain it under false pretenses. We define an adversary model that takes malicious activities into account. We have conducted experiments to demonstrate how different policies react to attacks using an on-line auction as the scenario","PeriodicalId":418337,"journal":{"name":"IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (SUTC'06)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116415201","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}

Significance of the study lies in the Eclectic Instructional Design Builder pattern, which bridges the gap between behaviourist, cognitivist and constructivist learning approaches; the case-based pattern which forms the basis for our case-based knowledge base, case-based search and modification of learning strategies and tasks to suit different contextual needs; and the unified content model pattern which enables dynamic retrieval and assembly of parts of learning objects","PeriodicalId":418337,"journal":{"name":"IEEE International Conference on Sensor Networks, Ubiquitous, and Trustworthy Computing (SUTC'06)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517973","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 All-teRrain Advanced Network of Ubiquitous mobile Asynchronous Systems (TARANTULAS) project builds a system of networked wireless sensors and actuators carried on mobile robots that are able to operate in all kinds of terrain. To achieve this objective involves the integration of three key research areas: robotics, ad hoc networking and, localization and positioning. We not only use the robots to improve the connectivity and localization of the sensor networks, they concurrently search for targets. In this paper, we present key elements of the algorithms and technologies developed by the project.
