1. 16. Security and Performance Analysis of Topology-Based Intrusion Detection System in Ad Hoc Networks

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Author : UMUNNA CHRISTIAN CHEZZ CHETACHI; [2009]
   Keywords : Ad-hoc networks; cluster topology; Intrusion detection system; jammer attack Security;

   Abstract : As Wireless ad-hoc Networks are becoming an increasingly emerging technology taking a centre stage in exciting research areas which has attracted many research attentions in communication systems, the need for efficient intrusion detection techniques to enhance network security and privacy has gained significant prominence. Intrusion detection systems(IDS) in ad- hoc networks provides an effective method to improve the security, energy efficiency of transmission nodes allowing better spatial reuse of the wireless channel and control over network resources in order to optimize node security and the transmit power thereby maintaining network connectivity.

3. 17. An Analysis of Collaborative Attacks on Mobile Ad hoc Networks

   University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

   Author : Cong Hoan Vu; Adeyinka Soneye; [2009]
   Keywords : MANET; Collaborative Attacks; Multiple Node; Blackhole;

   Abstract : A Mobile Ad hoc Network (MANET) consists of a set of communicating wireless mobile nodes or devices that do not have any form of fixed infrastructure or centralized authority. The security in MANET has become a significant and active topic within the research community. READ MORE

4. 18. Security in Wireless Mesh Network

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : SHAKEEL AHMAD GHUMMAN; [2009]
   Keywords : Security; wireless mesh networks; network management; WMNs;

   Abstract : The Master’s thesis report describes the wireless mesh networks functions, characteristics, network management and finally different protocols with security issues and applications. Wireless Networks (WMNs) are replacing wireless Infrastructure networks in many areas because of their lower and higher flexibility. READ MORE

5. 19. Security Threats in Mobile Ad Hoc Network

   University essay from Blekinge Tekniska Högskola/Avdelningen för för interaktion och systemdesign

   Author : Kamanashis Biswas; Md. Liakat Ali; [2007]
   Keywords : MANET; blackhole; wormhole; DoS; routing; TCP ACK storm; backoff scheme;

   Abstract : Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. READ MORE

6. 20. An evaluation of reputation spreading in mobile ad-hoc networks

   University essay from Institutionen för kommunikation och information

   Author : Martin Håkansson; [2004]
   Keywords : MANET; ad-hoc network; trust; security; opinion;

   Abstract : The use of mobile ad-hoc networks (MANETs) is growing. The issue of security in MANETs is not trivial, since such networks have no fixed infrastructure and therefor centralised security is not applicable. MANETs are also more sensitive to attacks due to their wireless communication channels and their spontaneous nature. READ MORE
