However, pervasive computing presents new challenges to existing mobile agent systems, especially the need for the context-aware self-configuring collaboration with the services provided by the physical objects. In order to address the problem, this paper presents a self-configuring personal agent platform to enable a mobile agent to adapt to the on-demand collaboration with the services. The platform consists of a Ubiquitous Intelligent Object (UIO) model the pervasive computing environment modeling, a code repository to provide executable codes which can be downloaded and instantiated as a mobile agent's capability at runtime, a service registry server for UIOs to publish and subscribe services, and personal agents, one for each individual user. A prototype of platform has been implemented as proof-of-concept and a preliminary performance study has also been carried out on it using a case study.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123287485","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 adversary has capability to monitor all external activities of system, to delay and to create messages in the system. Our proposal is to solve the limitation of APROB Channel which concerns only global delaying adversary. Pool-Based APROB Channel provides flexibility for users to justify their level of anonymity (and speed) and satisfies probabilistic real-time condition which ensures to deliver any message within a predefined duration with high probability. Experimental evaluation shows that our system provides lower source-hiding property than APROB Channel with the same environment and users' behaviors (rate and number of sent messages).","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125550505","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 ultimate goal of ubiquitous computing is to provide users with the way of computing anytime and anywhere. A necessary condition and/or fundamental assumption to underlie ubiquitous computing are that there certainly are computing systems working anytime available anywhere throughout the physical world. Therefore, ubiquitous computing must lead to requiring that computing systems can run continuously and persistently without stopping. However, all the existing testing and debugging techniques take programs of a system rather than the running system itself as the objects and/or targets, and assume that any program can be executed repeatedly with various input data only for testing and debugging without regard to stopping the task that program has to perform. In order to develop, use, and maintain persistent computing systems, we have to find a completely new methodology and its related techniques to test and debug a persistent computing system at run-time without stopping it. This is a completely new challenge in ubiquitous computing.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117204043","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}

Quite surprisingly, our hardware algorithm for Montgomery modulo multiplication of two dr-bit numbers can be completed in only d+1 clock cycles. Since most FPGAs have 18-bit multipliers and 18 k-bit block RAMs, it makes sense to let r=16. Our hardware algorithm for Montgomery modulo multiplication for 256-bit numbers runs only 17 clock cycles using redundant radix-64 k (i.e.radix-216) number system. The experimental results for Xilinx Virtex-II Pro Family FPGA XC2VP100-6 show that the clock frequency of our circuit is independent of d. Further, the hardware algorithm for 1024-bit Montgomery modulo multiplication using the redundant number system is 3 times faster than that using the conventional number system. Also, for 256-bit Montgomery modulo multiplication, our hardware algorithm runs in 0.322 mus, while a previously known implementation runs in 1.22 mus although our implementation uses less than a half slices.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122476904","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}

First, although the absolute RSS values change with time, the relative RSS (RRSS) values between several Access Points (APs) are more stable than the absolute RSSs. Thus, we can use RRSSs as rules for inferring a client's location. Second, when a unique location cannot be obtained based on RRSS rules, the localization process can backtrack to the previous observed client location. By analyzing the accessible paths on the floor plan, locations that are not reacheable from the previous location can be disqualified. Based on these two key observations, we propose several localization methods, implement them in a life environment and conduct extensive experiments to measure the localization accuracy of the proposed methods. We found that our methods achieve much higher accuracy than the state-of-the-art localization methods, namely, RADAR, LOCADIO and WHAM!.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116112595","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}

On the basis of NPCD-Agent model, this paper proposes a semantic model of multi-agent system (called MASNP), where cooperative problem solving (CPS) process is formally described. On the one hand, at the social level, the social constraint of agents can be specified by means of norms defined by the social administrators. And on the other hand, agents are instructed by polices presented by their owners. A case study shows that macro social constraint and instruction from agent's owner are both considered in CPS process, which makes the CPS process more reasonable.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134010319","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}
