A network layer security mechanism based on collaborative intelligent agents in MANET

A new network-layer security mechanism incorporating mobile agent security and grid technology is presented. The architecture of scheme is introduced along with the method to manage sub-network in grid format and the secure routing protocol. The storage space complexity and operational time of the new scheme are then analyzed. Simulation results show that the proposed mechanism is capable of achieving reliable performance in terms of packet delivery ratio when the network environment is insecure.
