With the rapid development of the cloud services conventional service discovery techniques using centralized registries stumble upon performance bottleneck and single point of failures. To address these issues

this paper proposes a semantic decentralized service discovery approach. This paper also introduces a multi-layered cloud ontology which closes the gap to represent cloud services in a standardized way. Here

service descriptions are mapped to a well-structured cloud ontology

which captures vital elements in different service description approaches. Peers are organized into clusters based on the semantic similarity of the service descriptions. To bolster the service discovery efficacy

semantic links are established between peers having higher similarity so that query forwarding is done only to relevant peers. Simulation results show that the proposed approach effectively enhances the query success rate and drops of the execution time.
