Mobile Adhoc Network(MANETS) : Proposed solution to Security Related Issues
Rachika Gupta · 2011
Most of the research in MANETS has been focused on Routing issues. Security on the other hand has been given low priority. This paper provides an introduction to Mobile Adhoc Networks, Routing related issues and overview of security problems MANETS, by distinguishing the threats on the basic mechanisms and security mechanisms. It then addresses the possible solution to protect the security mechanism, which involves availability, integrity, authentication and non repudiation. These securities related issues are well addressed if one can provide methods that are pertinent authentication, key distribution, and intrusion detection and Wireless cellular systems have been in use since 1980s. We have seen their evolutions to first, second and third generation's wireless systems. Wireless systems operate with the aid of a centralized supporting structure such as an access point. These access points assist the wireless users to keep connected with the wireless system, when they roam from one place to the other. The presence of a fixed supporting structure limits the adaptability of wireless systems. In other words, the technology cannot work effectively in places where there is no fixed infrastructure. Future generation wireless systems will require easy and quick deployment of wireless networks. This quick network deployment is not possible with the existing structure of current wireless systems. The next generation of wireless communication systems, there will be a need the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication emergency/rescue operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of Mobile Ad Hoc Networks. Mobile ad-hoc networks or short live networks operate in the absence of fixed infrastructure. They offer quick and easy network deployment in situations where it is not possible otherwise. Ad-hoc is a Latin word, which means for this or this only. Mobile ad-hoc network is an autonomous system of mobile nodes connected by wireless links; each node operates as an end system and a router all other nodes in the network.
