Here, each node of the investigated WSN may be randomly and alternatively in an ACTIVE status or a SLEEP status. When a referenced sensor node is in an ACTIVE status, it may generate data packets with a given stochastic process and may transmit/receive a data packet with a random period of time. However, when the referenced sensor node is in a SLEEP status, it may only be able to stochastically generate date packets but not transmit/receive. If all possible next-hop nodes of the referenced node are in SLEEP statuses, we will say the environment of the referenced node to be in an OFF period. If there exists at least one next-hop node of the referenced node to be in ACTIVE status, we will say that its environment is in an ON period. In this shorter paper, we first derive the steady-state probability distribution of number of data packets in the referenced node and then obtain the distribution function for a node to be in an ON period and in an OFF period, respectively. The novelty of this note is in its development of a stochastic model in WSN with active/sleep feature and the explicit results obtained for above two performance characteristics. These results are expected to be useful as the fundamental results in the theoretic analysis and design of various WSNs with active and sleep status consideration.","PeriodicalId":270249,"journal":{"name":"2011 4th IFIP International Conference on New Technologies, Mobility and Security","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137785","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}

In our opinion such an agile framework is needed for two main reasons. At first the cycle of introducing new services in the telecommunication industry usually takes several months, while the general cycles in the Web domain are much faster. Besides, customers want to use a flexible amount of services from different kinds of sources (e.g. Google, Facebook). The proposed agile service environment is intended to interact with services of the traditional telecommunication industry and is enabling the third party development process to support services coming from all kind of domains. Service platforms for Next Generation Networks adapting the principles of Service Oriented Architectures and the initial steps in the standardization towards service delivery frameworks are done. Special requirements that have to be considered are aspects of service life-cycle management and service composition that are critical regarding high performing real-time communication processes as needed in a telecommunications environment. Beyond the requirements of dynamic service deployment, management, evolution and service termination there is the intention of a well performing agile service composition mechanism. In order to fulfill the discussed requirements some related work in this area is presented and the promising IT / Network standards are enlightened. Furthermore, the architectural design of the developed framework is presented. Finally the paper demonstrates a practical use case scenario that shows the dynamic integration and combination of telecommunication services with services of the Web domain.","PeriodicalId":270249,"journal":{"name":"2011 4th IFIP International Conference on New Technologies, Mobility and Security","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121874891","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}

Nonetheless, due to its size and scope, this large network has become victim of its own success. Innovative approaches are required to overcome the shortfalls of current systems and to design Next Generation Internet. In this context, network virtualization presents a viable solution to deal with the current Internet impasse. It provides a promising way to deploy different network architectures and protocols over a shared physical infrastructure. However, in spite of its multiple advantages, network virtualization adds more complexity on network systems. A promising solution to address this huge complexity consists on developing systems which are capable of managing themselves, called autonomic computing systems or self-* systems. This paper proposes an agent-based autonomic framework which is able to self manage virtual resources. We provide a detail description of the proposed autonomic architecture and we focus on a real testbed implementation and testing of our framework. Experiment results show the ability of our system to self-configure its resources in order to maintain a required QoS level.","PeriodicalId":270249,"journal":{"name":"2011 4th IFIP International Conference on New Technologies, Mobility and Security","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473774","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}

Most of works which aim to protect these components generally consist in developing protections (or countermeasures) taken one by one. But this \"countermeasure-centered\" approach drastically decreases the performances of the whole chip in terms of power and speed. Our work is complementary and consists in reorganising a given set of existing countermeasures in order to optimise both the security and the availability of the circuit without reducing its global performances. The proposed solution is based on a double-processor architecture and on mechanisms to parametrise the hardware and software countermeasures. One processor embeds the state-of-the-art set of countermeasures and executes the application code. The second processor, much smaller, applies the strategy of security (i.e the response of the circuit when a security event arises), but without sharing sensitive data with the first processor. We show that our approach enables the secure circuit's designer to easily fine tune the strategy of security, for example, of Pay-TV applications and could, in the future, be used to optimise dynamically the trade-off between performance and security.","PeriodicalId":270249,"journal":{"name":"2011 4th IFIP International Conference on New Technologies, Mobility and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129854724","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}
