Location aided services (LAS) is a significant demand for wireless communication devices for service discovery and resource utilization in internet of things (IoT) environments. IoT devices provide services that are more significant about location and cost efficiency for both privacy and communication. In this paper, a location assisted delay-less service discovery (LDSD) for IoT users is introduced to minimize request–response delays. The proposed service discovery method searches cost effective resource for serving user requests with the knowledge of the resource location. With the knowledge of the location, LDSD classifies the resources based on service request delivery delay and availability for speedy resource mapping and service response. This resource discovery is also facilitated for replicated resource mapping considering service cost and request delivery delay ensuring minimum resource replication The performance of the proposed LDSD is verified through experiments and the benefit of the discovery method is assessed using the metrics: response time, failure rate, resource utilization, request delivery time, resource availability and service latency. Experimental results demonstrate the reliability of the proposed LDSD by minimizing response time, failure rate, request delivery time and service latency and improving resource utilization and availability.
