Wireless mobile ad-hoc networks are normal as networks except there is no static topology due to the mobility of interference, direction loss, multipath propagation and nodes, Hence a Routing protocol is needed for these networks to feature properly. The feature of protocols is to enable the exchange of information between computers or network devices using rules. Several routing protocols have been proposed for Ad-hoc networks however sometimes these protocols are susceptible to routing attacks like packet shedding and delayed packet forwarding, this is the major trouble in Ad-hoc network. This paper gives an overview of the protocols that are used in Ad-hoc network device and determined security features of all the protocols for secure data transmission.
