Abstract

A mobile ad hoc network MANET is a wireless network with high of mobility no fixed infrastructure and no central administration These characteristics make MANET more vulnerable to attack In ad hoc network active attack ie DOS and blackhole attack can easily occur These attacks could decrease the performance of the routing protocol In this chapter we proposed new trust mechanism that has the ability to detect and prevent the potentials attacks into a wireless ad hoc network especially for Denial of Service DOS and blackhole attacks We have proposed some modifications of AODV routing protocol with implemented a trust level calculation Our proposed mechanism will detect the attack by calculate local and global trust parameters When a node is suspected as an attacker the security mechanism will isolate it from the network before communication established To perform the trust calculation each node should get all the activity information from his neighbor In order to ensure the nodes can hear all the activities of his neighbors each node will run in promiscuous mode Simulation has been conducted using NS2 to evaluate our proposed protocol under dos and blackhole attack We compare the performance of our proposed protocol with existing secure routing protocol such as TCLS 14 LLSP 16 and RSRP 17 The simulation result shows that our proposed protocols outperform other secure protocols under DOS and blackhole attack in term of packet delivery ratio end to end delay and routing overhead We demonstrate that the proposed protocol improves significantly the performance of secure routing protocol
