The novel mobile agent techniques always are applied in about-mentioned topics. In the distributed network environment, message must move along the traces of mobile agent migrated to track the mobile agent when manager sent out the message. In fact, the mobile agent always migrates along circle round near the manager. For this reason, the trace of mobile agent migrated is not a shortest path for the message movement. This paper proposed a message delivery mechanism that is the MASPG (Mobile Agent Shortest Path with Guarantee algorithm). The MASPG can actively search shortest communication path and substitute communication path for the communication of manager with mobile agent. The MASPG message delivery mechanism utilizes the Network Initialization and MASPG algorithm to create the hierarchical tree for all nodes then exploits the information about connection states of node-to-node to search shortest communication path. The MASPG message delivery mechanism can shorten the distance of message delivery and decrease the time of the communication. Not only that the MASPG also can provide the guarantee of the message delivery to reduce the communication costs between manager and mobile agent when any connection on the shortest communication path is disconnect.
