Abstract

A mobile ad hoc network (MANETs) is an assortment of a variety of portable nodes that are linked collectively in a greater number in a wireless medium that has no permanent infrastructure. Here, all the nodes in the node partake in acting as both router and host and is in charge for accelerating packets to other nodes. This chapter discusses the various attacks on different layers and on various security protocols. So, designing a secure routing protocol is a main challenge in MANET. As we all know, this is a mobile ad hoc network so nodes in the network dynamically establish paths among each other so it is vulnerable to different kinds of threats. So, in this case, we need secured communication among the nodes present in the network.

Many research have been done about how to securely transmit audio data, in many research, dual safety measures by encrypting and decrypting the audio at each node in the route using stream ciphering method has been presented. Secure Multiparty Computation is discussed and how modification of data is done using optimization technique. Various security problems have been explained which are adopted in the network layer. Security issues regarding data query processing and location monitoring have been illustrated in many research articles (Rashid Sheik, Mahakal Singh Chandel and Durgesh Kumar Mishra, (2012). Security solution for the routing protocol OLSR (Optimized Link State Routing) is being proposed in some articles as shown in Table 1.

Table 1.
Different kinds of Secured OLSR Protocol
S.No.Name of the protocolAdvantagesDisadvantages
1.OLSR-SDK (Secure Data Key)It provides sophisticated safety measures and enhanced traffic performance.The Packet Delivery Ratio does not get better.
2.RA-OLSR (Radio Aware)It provides sophisticated safety measures.It has major impact on traffic performance.
3.COD-OLSR()It does not generate a major traffic load.It cannot cancel out strict attacks.
4.Secure traffic routing OLSRIt battles against link – spoofing attack.It has main effect on routing performance and it does not discard aggressive attacks.
5.Trust to secure OLSRIt has fine routing presentation in a extremely damaged environment.It does not provide sophisticated security against compound attacks.
