Service Placement in Ad Hoc Networks

Service provisioning in ad hoc networks is challenging given the difficulties of communicating over a wireless channel and the potential heterogeneity and mobility of the devices that form the network Service placement is the process of selecting an optimal set of nodes to host the implementation of a service in light of a given service demand and network topology The key advantage of active service placement in ad hoc networks is that it allows for the service configuration to be adapted continuously at run time i Service Placement in Ad Hoc Networks i proposes the SPi service placement framework as a novel approach to service placement in ad hoc networks The SPi framework takes advantage of the interdependencies between service placement service discovery and the routing of service requests to minimize signaling overhead The work also proposes the Graph Cost Single Instance and the Graph Cost Multiple Instances placement algorithms

Sicherheitsforschung Im Dialog: Beitraege Aus Der Interdisziplinaeren Ringvorlesung Wie Sicher Wollen Wir Leben? Des Forschungsforum Oeffentliche Sicherheit

Das Buch ist eine Einfuhrung in das interdisziplinare Thema der Sicherheitsforschung und eine Aufforderung zu einem kritischen Dialog uber eine neue Sicherheitskultur in unserer Gesellschaft Expertinnen und Experten stellen in diesem Sammelband das Themenspektrum der Offentlichen Sicherheit vom technisch Moglichen bis hin zum gesellschaftlich Akzeptierten dar und diskutieren aus naturwissenschaftlich technischer als auch geistes und sozialwissenschaftlicher Perspektive Die Publikation ist hervorgegangen aus einer Ringvorlesung mit dem Titel Wie sicher wollen wir leben Sicherheitsforsc hung im Dialog die im Wintersemester im Rahmen des Offenen Horsaals an der Freien Universitat Berlin durchgefuhrt wurde Ziel der Vorlesung war es den durch das Forschungsforum Offentliche Sicherheit initiierten und fachlich ausdifferenzierten Diskurs um Sicherheit in die interessierte Offentlichkeit zu tragen und einen Beitrag zum Wissenstransfer zu leisten
