ABSTRACT:
A system and method of performing device detection and service discovery in a mobile ad hoc communications network, each network node storing a local application directory. One of the network nodes is selected to be a directory server node that stores a combined application directory. The directory server node sends an inquiry message to a listening node when the listening node enters the coverage area of the directory server node. The listening node sends a notification message to the directory server node that includes the local application directory stored in the listening node. The directory server node compares the received local application directory to the combined application directory and updates the combined application directory accordingly. The directory server node sends an update message to each network node by sending an update portion of the combined application directory. Each network node updates the local application directories accordingly.
