Security Issues in Mobile Devices and Mobile Adhoc Networks

Abstract

For successful data transmission in wireless networks, security features are very much essential to implement. A mobile adhoc network contains a set of autonomous mobile stations that can correspond with each other instead of some adverse situation of wireless environment. Those mobile nodes that are not in the same series can communicate with others through intermediate hops. Security is a challenging mission in mobile adhoc network (MANET) due to many serious issues in the network such as hop-to-hop persistent wireless connectivity, high frequency of variation in topology of the network, and increasing rate of link failure due to higher mobility. So, it is very challenging to develop a secured, dynamic, and efficient routing protocol for such a magnificent network. In this chapter, vulnerability issues of MANET are focused on with a spotlight on prominent MANET protocols. A brief study on technical issues responsible for vulnerability in MANET has been depicted with systematic review on various issues and protocols that provide secured routing in the network.
