Abstract

Security in Mobile Ad hoc Network (MANET)/ Wireless Sensor Network (WSN) is very important issue. Due to dynamic topology and mobility of nodes, Mobile Ad hoc Networks/ WSNs are more vulnerable to security attacks than conventional wired and wireless network. Nodes of Mobile Ad hoc Network communicate directly without any central base station. That means in ad hoc network, infrastructure is not required for establishing communication. In this chapter we are describing Route Falsification Attack which is easy to launch in MANETs or wireless ad hoc network. Route Falsification attack is referred to as a node with no special hardware capability can use packet encapsulation and tunneling to create bogus short-cuts in routing paths and influence data traffic to flow through them. This chapter shows the implementation of a Secure Hybrid Routing Information Protocol (SRIP) which can be used to prevent route falsification attack in MANETs. We evaluated performance of SRIP in Qualnet Simulator with and without route falsification attack. Our analysis indicates that SRIP is very suitable to stop this attack and performs well with low overhead in normal networks.

Background

There are lots of researches have been going on and conducted on the topic of security. Wireless Sensor network is the very accepted area. Wireless sensor networks are often deployed in a hostile environment and work without human supervision, individual node could be easily compromised by the malicious node due to the constraints such as battery lifetime, smaller memory space and limited computing capability. Security in WSN has been one of the most important topics in the WSN research community. Here we only briefly review the reported works closely related to malicious node detection due to the limited space. To identify denial of service vulnerabilities, A.D. Wood and J. A. Stankovic (2002) analyzed two effective sensor network protocols that did not initially consider security. In their examples, they demonstrated that consideration of security at design time is the best way to ensure successful network deployment. Most recent ad hoc network research has focused on providing routing services without considering security. In their paper, B. Dahill, B. N. Levine, E. Royer & C. Shields. Aran (2002) detailed security threats against ad hoc routing protocols, specifically examining AODV and DSR. They proposed protocol, ARAN, that was based on certificates and successfully defeats all identified attacks. C.Karlof & D. Vagner (2003) proposed security goals for routing in sensor networks, showed how attacks against ad-hoc and peer-to-peer networks can be adapted into powerful attacks against sensor networks, introduced two classes of novel attacks against sensor networks––sinkholes and HELLO floods, and analyzed the security of all the major sensor network routing protocols. H. Yang, H. Luo, F. Ye, S. Lu & L. Zhang (2004) focused on the fundamental security problem of protecting the multihop network connectivity between mobile nodes in a MANET. They identify the security issues related to this problem, discuss the challenges to security design, and review the state-of-the-art security proposals.
