This paper presents a routing algorithm based on mobile agent to block the wormhole attacks in Ad Hoc network.Traversing over the whole network,a few mobile agents communicate with each node to collect the network connection information to build the global information matrix of nodes by which data packets are determined to be routed and transferred according to a breadth_first search algorithm.Experiment is done in simulated environment of NS-2 system.Having the global information matrix in its cache,every node is familiar with the geographical position of other nodes in the network to defend the wormhole attacks efficiently.This approach needs fewer moving agents to get more global information.Therefore it reduces the overhead by only maintaining the routing information on each node.It is very efficient and robust to transfer packets rapidly.
