Location based services (LBS) are expected to play crucial role in future of e-commerce. Although, LBS consider service provision on the basis of location, but don't take into consideration time aspect and user's interests. We propose incorporation of time-awareness and demand-oriented contexts along with location to develop idea of community pervasive services (CPS).To identify appropriate service provider subjected to real-time constraint in highly dynamic operational environment of autonomous decentralized community system (ADCS), efficient searching technique is required. Many existing resource discovery strategies in area of peer to peer and wireless ad hoc network can be captured by the n-ring model, which can't meet real time requirements in highly unpredictable and dynamic operating environment of ADCS. Therefore, we present novel idea of steady expanding search coupled with snail's pace advancement and swift boundary confining mechanism to seek appropriate service provider. Simulation results verify the effectiveness of the proposed technique.
