This paper modifies the Chord protocol and results in a new resource lookup protocol, the Crown protocol, which is suitable for mobile and wireless network environment. In Chord, all peers are connected to form a single ring topology, while Crown protocol adds concept of group and expands the ring to a group-ring. Besides, Crown adds a replica mechanism and a fault-recovery mechanism to strengthen the group-ring topology, and enhances the availability and reliability of resources. The group-ring concept makes the whole topology more stable when peers join or leave frequently.
