A survey of trust based secure routing protocol used in mobile ad hoc networks

Abstract

A mobile ad hoc network (MANET) is a dynamic wireless network developed using wireless nodes without using any infrastructures. The significant features of MANET are low-cost infrastructure, self-organization, mobility, and rapid deployment which offer the opportunity to deploy it for various applications such as disaster relief, environmental monitoring and military communications. The wireless nature of mobile networks causes the susceptible to malicious attacks. Therefore, security is turned out an essential factor to ease the secured message transmission among mobile nodes in the wireless medium. In this paper, the significant definition of the secure routing protocol is designated with its merits. Since there are various types of secure routing developed for accomplishing the secure transmission over the MANET. This paper studies the different types of existing routing methods such as optimization-based routing, and key encryption-based routing used in the MANET. The packet delivery ratio, energy consumption and end-to-end delay are considered key parameters for defining the effectiveness of secure routing protocols. This comprehensive research supports the researchers to obtain the best solutions for the current issues in the secure routing of MANET.
