A host device configured to transmit information to at least one device comprised in a routing path, the host device comprising:

• at least one processor;
• a memory storing instructions executed by the at least one processor;
• the at least one processor configured to:
• search for devices that are communicable with each other or the host device;
• generate routing paths for data transmission to connect the host device to a client device via the devices searched by the host device, and
• select one of the routing paths according to a preset reference;
• and
• a communicator configured to transmit information to the client device via at least one of the searched devices included in the selected routing path,
• wherein the preset reference comprises:
• a first reference that is set according to a service executed by the host device, or
• a second reference that is set according to a security level of each of the searched devices,
• wherein the communicator is further configured to transmit, to the client device, information related to the service executed by the host device, and
• wherein the communicator is further configured to transmit information for allowing the client device to execute a service that is executable by the at least one of the searched devices in the selected routing path.
