Security Issues in MANETs
Abhishek Seth 04329001
Mobile Ad hoc Networks (MANET) has become an exÃ‚Â¬citing and important technology in recent years because of the rapid proliferation of wireless devices. A moÃ‚Â¬bile adhoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a Mobile Adhoc Network usually seek the help ofother intermediate nodes to establish communication channels. In such an environment, malicious intermeÃ‚Â¬diate nodes can be a threat to the security of converÃ‚Â¬sation between mobile nodes. The security experience from the Wired Network world is oflittle use in WireÃ‚Â¬less …show more content…
2 Mobile Adhoc Networks
Mobile Adhoc Network (MANET) is a collection of in-dependent mobile nodes that can communicate to each other via radio waves. The mobile nodes that are in radio range of each other can directly communicate, whereas others needs the aid of intermediate nodes to route their packets. These networks are fully disÃ‚Â¬tributed, and can work at any place without the help of any infrastructure. This property makes these netÃ‚Â¬works highly flexible and robost.
The characteristics of these networks are summarized as follows:
Â¢ Communication via wireless means.
Â¢ Nodes can perform the roles of both hosts and routers.
Â¢ No centralized controller and infrastructure.
Â¢ Intrinsic mutual trust.
Â¢ Dynamic network topology.
Â¢ Frequent routing updates.
2.2 Advantages and Applications
The following are the advantages of MANETs:
Â¢ They provide access to information and services regardless of geographic position.
Â¢ These networks can be set up at any place and time.
Some of the applications of MANETs are
Â¢ Military or police exercises.
Â¢ Disaster relief operations.
Â¢ Mine cite operations.
Â¢ Urgent Business meetings.
