Design and quantitative analysis of protocols for epidemic information disseminationin mobile ad hoc networks
نویسنده
چکیده
Die vorgestellte Arbeit [Wal05] beschäftigt sich mit dem Gebiet der Protokolle für die epidemische Verbreitung von Informationen in mobilen Ad-hoc Netzen (MANET). Solche Protokolle nutzen die in diesen Netzen vorhandene Mobilität und übertragen Informationen, wenn sich zwei Geräte ,,begegnen“ (d.h. sich in Funkreichweite befinden), ähnlich der Übertragung einer ansteckenden Krankheit zwischen Individuen. Die Arbeit setzt sich aus drei Forschungsbeiträgen in diesem Gebiet zusammen. (1) Ein universell einsetzbarer verteilter Suchdienst für mobile Anwendungen in MANET wird vorgestellt, der auf epidemischer Verbreitung von Einträgen eines verteilten Index beruht. (2) Verschiedene Mechanismen zur Verbreitung von Präsenzinformationen in einem MANET werden untersucht und basierend auf den Ergebnissen dieser Untersuchungen ein Präsenzdienst für ein mobiles Instant Messaging System vorgeschlagen. (3) Ein neuartiger stochastischer Modellierungsansatz zur Analyse und Optimierung von Systemen zur epidemischen Informationsverbreitung wird vorgeschlagen und auf ein existierendes System angewendet.

Design and evaluation of two scalable protocols for location management of mobile nodes in location based routing protocols in mobile Ad Hoc Networks
Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

متن کاملA New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملA Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks
In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
