Locating appropriate service and communicating it to the
requester at the point of need within the shortest possible
time is a key issue in ubiquitous health service provisioning. Failure to provide the health service at the
exact time needed can result in erroneous diagnosis and
treatment. Hence, there is a need for real time service
discovery of requested services for prompt healthcare
service provisioning. This paper proposes a peer-to-peer
health service discovery solution that discovers and
maintains a set of shortest service path to existing
healthcare service types within a distributed health service network. We introduce an optimal service path cache
(OSPC) for maintaining the shortest service paths provided by learning automata mapped to the super-nodes. The proposed solution was compared with existing methods and showed an improved performance in service discovery.
