An Efficient Secure Zone Based Routing Protocol for Mobile Adhoc Network

Abstract

An ad hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. There is an increasing trend to adopt ad hoc networking for commercial uses; however, their main applications lie in military, tactical and other security-sensitive operations. In these and other applications of ad hoc networking, secure routing is an important issue. Most of the secure routing protocols proposed in the literature are either proactive or reactive in nature. In this paper, we proposed a secure hybrid routing protocol for adhoc network, called Modified Secure Zone Routing Protocol (MSZRP), which is based on the concept of Zone routing protocol (ZRP). The paper details the design of the proposed protocol and analyses its robustness in the presence of multiple possible attacks that involves impersonation, modification, fabrication and replay of packets caused either by an external advisory or an internal compromised node. MSZRP successfully defeats all the identified threats. It is also resilient against the multilayer DoS attack
