One of the key features of this model is that it allows formal verification of deployment specifications. The paper also describes how the proposed conceptual model can be represented directly using some of the new modeling features of the industry-standard UML 2.0 language. Finally, we briefly describe how this model can be used to support platform-independent design while still accounting for the potentially fundamental impact that platform characteristics can have on key design decisions.","PeriodicalId":377002,"journal":{"name":"Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'05)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121657076","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}

Due to the characteristics of sensor devices links and communications. The existing protocols for the traditional ad hoc networks affect the performance of the system in wireless sensor network. In this paper, multipath disjoint (MPD) routing algorithm is proposed. We compare MPD with two on-demand protocols, DSR and AODV. The simulation results show that MPD improves the packet delivery ratio, saves power and reduces the end-to-end delay. As a result, MPD releases the network congestion quite well. The system does not bring paralysis because of the routing breakdown.","PeriodicalId":377002,"journal":{"name":"Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114981144","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}

Building responsive TMR-based servers in presence of timing constraints 在存在时间限制的情况下构建响应性的基于tmr的服务器

{"title":"Building responsive TMR-based servers in presence of timing constraints","authors":"P. Ezhilchelvan, J. Hélary, M. Raynal","doi":"10.1145/571825.571843","DOIUrl":"https://doi.org/10.1145/571825.571843","url":null,"abstract":"This paper is on the construction of a fault-tolerant and responsive server subsystem in an application context where the subsystem is accessed through an asynchronous network by a large number of clients. The server is made fault-tolerant by the triple modular redundancy (TMR) technique: at least two server processes behave correctly, while the third one can behave arbitrarily. An essential requirement for process replication is that the client inputs be delivered to server replicas for processing in an identical order. Moreover, in order to cope with process' memory requirement, a time bound constraint is imposed: no client input can stay in the local memory of server process more than /spl Sigma/ units of time. Based on known technologies, two assumptions are made: (1) the network delivers a given client input to any two server processes within a known bounded time (D), and (2), there is an Ordered Timed Atomic Broadcast protocol built on top of the TMR system with timeliness A. The paper presents two results. The first is a protocol that delivers an ordered stream of client inputs, such that every client input is delivered exactly once to each correct server, thus eliminating redundant verification. It works under the assumption /spl Sigma/>D+/spl Delta/. The second is an impossibility result, namely there can be no ordering protocol when /spl Sigma/<D+/spl Delta/_, where /spl Delta/_ is the minimum timeliness of any reliable broadcast protocol that can be implemented on top of the TMR server (/spl Delta/_ < /spl Delta/).","PeriodicalId":377002,"journal":{"name":"Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'05)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002637","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}
