“…This type of security management focuses on prevention technique, as it presents a set of management mechanisms based on trust and reputation to prevent malicious nodes from entering the trusted community. Moreover, depending solely on the trustworthiness and reputation of nodes is not suitable for applications where high degrees of accountability and security are required [5,29,112].…”

Abstract II AbstractMobile Ad hoc Network of Networks (MANoN) are a group of large autonomous wireless nodes communicating on a peer-to-peer basis in a heterogeneous environment with no pre-defined infrastructure. In fact, each node by itself is an ad hoc network with its own management. MANoNs are evolvable systems, which mean each ad hoc network has the ability to perform separately under its own policies and management without affecting the main system; therefore, new ad hoc networks can emerge and disconnect from the MANoN without conflicting with the policies of other networks.The unique characteristics of MANoN makes such networks highly vulnerable to security attacks compared with wired networks or even normal mobile ad hoc networks.This thesis presents a novel security-management system based upon the Recommendation ITU-T M.3400, which is used to evaluate, report on the behaviour of our MANoN and then support complex services our system might need to accomplish.Our security management will concentrate on three essential components: Security Administration  Prevention and Detection  Containment and RecoveryIn any system, providing one of those components is a problem; consequently, dealing with an infrastructure-less MANoN will be a dilemma, yet we approached each set group of these essentials independently, providing unusual solutions for each one of them but concentrating mainly on the prevention and detection category. Abstract IIIThe contributions of this research are threefold. First, we defined MANoN SecurityArchitecture based upon the ITU-T Recommendations: X.800 and X.805. This security architecture provides a comprehensive, end-to-end security solution for MANoN that could be applied to every wireless network that satisfies a similar scenario, using such networks in order to predict, detect and correct security vulnerabilities. The security architecture identifies the security requirements needed, their objectives and the means by which they could be applied to every part of the MANoN, taking into consideration the different security attacks it could face.Second, realising the prevention component by implementing some of the security requirements identified in the Security Architecture, such as authentication, authorisation, availability, data confidentiality, data integrity and non-repudiation has been proposed by means of defining a novel Security Access Control Mechanism based on Threshold Cryptography Digital Certificates in MANoN.Network Simulator (NS-2) is a real network environment simulator, which is used to test the performance of the proposed security mechanism and demonstrate its effectiveness.Our ACM-MANoN results provide a fully distributed security protocol that provides a high level of secure, available, scalable, flexible and efficient management services for ...

RESUMENSe evalúan algunas características presentadas a la hora de garantizar calidad de servicio como son el ancho de banda y la pérdida de paquetes, sobre una topología de red que involucra tres tipos de tráfico (CBR, Pareto y Exponencial). Se implementan cinco configuraciones diferentes en el simulador de redes NS2, donde el primero corresponde a un caso sin QoS, con una capacidad de canal que es suficientemente grande para trasmitir los tres tipos de tráfico, mientras que en las siguientes cuatro configuraciones la capacidad se reduce a un menor tamaño y se estudian diferentes casos de calidad de servicio. Para observar el comportamiento de los tráficos se implementa inicialmente una red sin QoS con dos tipos de encolamiento y posteriormente se realiza una configuración que implementa QoS mediante los modelos IntServ y DiffServ. Los resultados obtenidos de estas simulaciones son graficados y comparados con el fin de determinar el comportamiento más adecuado en redes IP. ABSTRACTThis paper presets some of the characteristics that are present when attempting to guarantee Quality of Service (QoS) (e.g. bandwidth, packet loss) over a network topology that involves three types of traffic, namely CBR, Pareto y Exponential. Five configurations are implemented using NS2, the first corresponds to the case where no QoS is required and the channel capacity is large enough to cope with the three types of traffic, while in the four remaining configurations channel capacity is reduced in order to study QoS performance under different conditions. In order to observe traffic behavior, a network without QoS is simulated including two types of queuing policies. Subsequently, a different configuration that includes QoS is deployed by using models like IntServ and DiffServ. Results are plotted and compared to determine the most convenient traffic behavior between IP networks.

“…Through a simulation environment, many conditions can be studied such as scalability that is difficult to simulate in a real environment because of its very high cost, such as simulation of the dynamic and multipoint virtual private networks. Several scientific research simulators can be www.ijacsa.thesai.org used as OPNET Modeler, NS2… [8,9,10], but managing a dynamic and multipoint VPN under OPNET Modeler simulator requires firstly a mastery of the tool and secondly the technology, this is a good motivation to develop a system for automatically creating projects for various architectures of the same network, for this reason we have created an automation model for simulating dynamic multipoint and multi architectures Virtual Private Network, and a GUI man/machinery application designed for this type of networks.…”
