Reasons are unreliable network connectivity, resource limitations of devices, and energy restrictions in general. Consequently, software deployment has to be performed with great care otherwise resources might be wasted or nodes become unavailable due to failed updates. The overall objective for software management in sensor networks is to enable a robust and efficient way to build deployable software images that take into account all the needs from application requirements to node-specific resource restrictions. In this article, we outline the current state-of-the-art for software management in WSN and (network-based) sensor network (re-)programming. We provide insights into three different approaches enabling a more comprehensive management of WSN while challenging the robustness and efficiency of software configurations and reprogramming. Additionally, we outline research challenges in the area of software management and sensor network operation.","PeriodicalId":191295,"journal":{"name":"2007 2nd International Conference on Communication Systems Software and Middleware","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131252109","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}

With VPN, we can securely access to resources in the organizational network via the Internet. In VPNs having hierarchical structure, since each VPN domain has different access policy (whether VPN gateway should perform authentication, data encryption, and so on or not), an administrator of a VPN domain may need to configure access policies which are different from every VPN sub-domain. However, in the existing VPN methods, since access policies are stored in a static configuration file of each VPN gateway, an administrator of a VPN domain has to cooperate with the other administrators of its sub-domains. Therefore, management cost of access policies becomes considerably large if the organization has large and complicated structure. In this paper, we propose an efficient management method of access policies for hierarchical VPNs. In order to reduce management cost, we introduce a database with hierarchical structure to represent access policies easily and policy servers to get access policies automatically. The effectiveness of our proposed method is confirmed by an experiment on an actual network using policy servers based on the proposed method.","PeriodicalId":191295,"journal":{"name":"2007 2nd International Conference on Communication Systems Software and Middleware","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114235824","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}

A sensor network operates on an infrastructure for sensing, computation, and communication, through which it perceives the time evolution of physical dynamic processes in its operational environment. Hence the communications and computation software that enables the distributed time critical interactions of individual devices is characteristically different from traditional software. In particular, the operational environment for its execution is not predetermined and operational specifications are dynamic and therefore difficult to pin down. Hence existing programming methods like structured programming are not applicable. The ad hoc build, test, scrap approach will not work. This paper presents a deliberate high assurance design and debugging methodology, akin to the spiral model for software development, for building and validating dynamic, interoperable, programmable applications of sensor networks that involve management, information gathering, querying and tasking of the nodes for resource-constrained time-critical missions. A middleware architecture has been developed for sensor networks that extends agent communication languages for designing specific behaviors of sensor networks. Building on this architecture, we develop a high assurance software design coordination network for designing and validating dynamic agents that maintain desired behaviors of sensor network software despite faults, failures, uncertainties and environmental perturbations.","PeriodicalId":191295,"journal":{"name":"2007 2nd International Conference on Communication Systems Software and Middleware","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121796723","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}
