A Survey of Trust Based AODV Routing Protocols in MANETS

Mobile Adhoc Networks are type of wireless network which are infrastructure less, self organizing, highly mobile and quickly deployable. There is no central authority, the communication occur hop by hop based on cooperation among the nodes. Thus, secure routing protocols are needed which are robust and ensure that the nodes in the network behave in trustworthy manner otherwise detect and eliminate the untrustworthy nodes which degrade the overall network performance. There are several trust based AODV routing protocols given in the past. In this paper, we have given a survey of trust based AODV, in which concept of TRUST is used to ensure secure routing and improved network performance.
