Titel / Title: Security Threats in Mobile Ad Hoc Network
Abstrakt 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. Although the ongoing trend is to
adopt ad hoc networks for commercial uses due to their certain unique properties, the
main challenge is the vulnerability to security attacks. A number of challenges like open
peer-to-peer network architecture, stringent resource constraints, shared wireless
medium, dynamic network topology etc. are posed in MANET. As MANET is quickly
spreading for the property of its capability in forming temporary network without the aid
of any established infrastructure or centralized administration, security challenges has
become a primary concern to provide secure communication. In this thesis, we identify
the existent security threats an ad hoc network faces, the security services required to be
achieved and the countermeasures for attacks in each layer. To accomplish our goal, we
have done literature survey in gathering information related to various types of attacks
and solutions, as well as we have made comparative study to address the threats in
different layers. Finally, we have identified the challenges and proposed solutions to
overcome them. In our study, we have found that necessity of secure routing protocol is
still a burning question. There is no general algorithm that suits well against the most
commonly known attacks such as wormhole, rushing attack etc. In conclusion, we focus
on the findings and future works which may be interesting for the researchers like robust
key management, trust based systems, data security in different layer etc. However, in
short, we can say that the complete security solution requires the prevention, detection
and reaction mechanisms applied in MANET.
