Recently, mobile nodes (smartphones) used by many users have both cellular (4G/LTE) and short range ad hoc (wifi) connections. A mobile node can connect with the cellular network by the cellular connection and communicate with a distant mobile node, while it can configure a multi-hop network (mobile ad hoc network) and communicate with nearby nodes by the short range ad hoc connection. For information dissemination, if all the messages are disseminated by cellular networks in any types of applications and services, the cellular base stations incur heavy overload. Therefore, in this paper, we propose an information dissemination scheme using mobile agents in heterogeneous wireless network which combines a cellular network and a mobile ad hoc network. At first, the proposed scheme disseminates data messages with lower number of cellular base stations to some specified mobile nodes in the cellular network. Then, it disseminates data messages from the specified nodes to all nodes by mobile agents in the mobile ad hoc network.
