Neuware -Al no disminuir el uso de las comunicaciones inalámbricas y proliferar a gran velocidad la investigación en tecnología móvil, las redes móviles ad hoc (MANET) se han utilizado ampliamente para diversas aplicaciones, como operaciones militares de crisis y operaciones de rescate de emergencia. La ausencia de infraestructuras y la topología dinámica de MANET hacen que estas redes sean muy vulnerables a diversos problemas de seguridad, como la explotación de vulnerabilidades de los protocolos de enrutamiento y la inyección de paquetes dañinos en la red, entre otros. El deterioro de estas amenazas causa graves daños a la red. El reto es cómo prevenir estas amenazas de seguridad en MANETs. Basándose en el protocolo AODV, se propone un esquema de detección denominado Esquema de Detección Cooperativa (CDS), cuyo objetivo es detectar y prevenir que los nodos afectados lancen ataques de agujero gris/agujero negro colaborativo en MANETs.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Spanisch.

Taschenbuch. Condición: Neu. Neuware -With no dwindling in the use of wireless communication and a corresponding speedy proliferation of research in mobile technology, Mobile Adhoc Network (MANET) have been widely used for various applications such as military crisis operations and emergency rescue operations. The infrastructure-less nature and the dynamic topology features of MANET makes these networks highly vulnerable to various security issues like exploiting vulnerabilities of routing protocols and injecting harmful packets in the network etc. These threats deteriorate causes severe damage to the network. The challenge is how to prevent these security threats in MANETs. Based on AODV protocol, propose a detection scheme called the Cooperative Detection Scheme (CDS), which aims at detecting and preventing affected nodes launching gray hole/collaborative black hole attacks in MANETs.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Da die Nutzung der drahtlosen Kommunikation nicht nachlässt und sich die Forschung im Bereich der Mobilfunktechnologie entsprechend schnell ausbreitet, werden mobile Ad-hoc-Netze (MANET) in großem Umfang für verschiedene Anwendungen wie militärische Kriseneinsätze und Notfallrettungsaktionen genutzt. Die infrastrukturlose Natur und die dynamischen Topologieeigenschaften von MANET machen diese Netze sehr anfällig für verschiedene Sicherheitsprobleme wie das Ausnutzen von Schwachstellen in Routing-Protokollen und das Einschleusen schädlicher Pakete in das Netz usw. Diese Bedrohungen führen zu schweren Schäden im Netzwerk. Die Herausforderung besteht darin, wie man diese Sicherheitsbedrohungen in MANETs verhindern kann. Auf der Grundlage des AODV-Protokolls wird ein Erkennungsschema namens Cooperative Detection Scheme (CDS) vorgeschlagen, das darauf abzielt, betroffene Knoten zu erkennen und zu verhindern, dass sie graue Löcher/kollaborative schwarze Löcher in MANETs starten.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Deutsch.

Queste minacce peggiorano e causano gravi danni alla rete. La sfida è come prevenire queste minacce alla sicurezza nelle MANET. Sulla base del protocollo AODV, proponiamo uno schema di rilevamento chiamato Cooperative Detection Scheme (CDS), che mira a rilevare e prevenire i nodi colpiti che lanciano attacchi gray hole/collaborative black hole nelle MANET.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Italienisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Cloud computing is an encouraging and favorable paradigm for both providers and consumers in diverse scopes of endeavors. Software as a Service (SaaS) is a method of conveying services or applications through the Internet as a service, and it is known to be one of the very crucial computing services in cloud computing. Cloud computing has become a major medium for the SaaS providers to provide their applications so as to meet required scalability. The challenges of SaaS placement process depends on various factors comprising cloud network size, resource requirements, and communication among its components. This text analyzes the SaaS Placement Problem (SPP) and proposes a mathematical model for SaaS placement in the cloud. A Particle Swarm Optimization (PSO) based approach has been applied to solve the optimal placement of the SaaS component so as to minimize the total cost incurred to the SaaS provider, and then evaluated against the traditional Greedy approaches. 68 pp. Englisch.
