Abstract
Embodiments of a system and method for using mobile agents in peer-to-peer networks to gather presence information for determining active peers in groups of peers. In one embodiment, a mobile agent may be launched by an initiating peer in a peer group to attempt to visit each member peer in a peer group. The itinerary of the mobile agent may include information for accessing each member peer of the peer group. The mobile agent may return to its initiating peer with a payload indicating which of the member peers it was successful in contacting and visiting. When the mobile agent returns to the originating peer, the originating peer may update presence information indicating presence of member peer nodes in the group in accordance with the indications provided by the mobile agent.
