Abstract

Security is very essential in both wired and wireless network communication. Network security is an important criterion for wired and wireless communication. The advancement in wireless technologies and the high availability of wireless equipment in everyday devices is a factor in the success of infrastructure-less networks. MANETs are becoming more and more common due to their ease of deployment. The high availability of such networks and the lack in security measures of their routing protocols are alluring a number of attackers to interrupt. An ad hoc network is a collection of number of wireless computers having dynamically changing topology due to which the security issues are more in case of wireless networks. In recent year with the widespread use of mobile device, Mobile Ad hoc networks (MANETs) technology has been attracted attention day by day. In this paper, our aims to propose a trust based model for defending network from the severe types of network attack i.e. black-hole and wormhole attack. So this paper present the survey analysis of the existing approaches based of attack prevention.

Introduction

Ad-hoc networks are a key in the evolution of wireless networks [1]. Ad-hoc networks are typically composed of equal nodes, which communicate over wireless links without any central control. Although military tactical communication is still considered as the primary application for ad-hoc networks, commercial interest in this type of networks continues to grow. Applications such as rescue missions in times of natural disasters, law enforcement operation, commercial and educational use, and sensor networks are justfew possible commercial examples. Ad-hoc wireless networks inherit the traditional problems of wireless and mobile communications, such as bandwidth optimization, power control and transmission quality enhancement. In addition, the multi-hop nature and the lack of fixed infrastructure generate new research problems such as configuration advertising, discovery and maintenance, as well as ad-hoc addressing and self-routing.

Conclusion

MANETs require a reliable, efficient, and scalable most importantly, a secure protocol as they are highly insecure, self-organizing, rapidly deployed and they use dynamic routing. The mobile ad hoc network is one of the most popular network technologies now in these days. In recent years the widespread availability of wireless communications, mobile computing and handheld devices has led to the growth and significance of wireless mobile ad hoc networks. Though there have been many works in the recent years on secure routing protocols. This survey paper initiate key defense against network attack i.e. black-hole and wormhole in MANET and also explore initial trust based approach, and how these solutions are capable to safe the network So the finally, by evaluate the pros and cons of obtainable techniques the open research challenges in mobile ad-hoc network are studied.
