چکیده مقاله

Ad-hoc mobile networks are free of any specific infrastructure in which, their nodes act in a moving and totally autonomous form and communicate with each other through radio waves. Communication among nodes is subject to change at any moment due to the emergence of new nodes in the network. Therefore, the security of these networks is of great importance. In this paper, we study different types of routing protocols, security problems in the routing of ad-hoc mobile networks, and various types of secure routing protocols, along with their advantages and disadvantages. By applying some changes over the SPR protocol, we attempt to solve problems associated with the Worm Hole attacks using a new combination of packet leashes techniques. That is by adding another technique as status leashes to the SPR Protocol which is based on the encryption information and security features, the exchange of packets in the route is tracked and controlled. Moreover, for key management and security enhancement we used Diffie-Hellman algorithm and finally for the implementation of the proposed method Matlab as a tool and C# programing language were used.
