Despite the increasing number of mobile heterogeneous network elements (NEs) interconnected through the Internet, all of them setting the foundations for an agile IoT development, many issues remain still unsolved. The scalability of the current host-oriented Internet model is one of these problems. In this paper, we present a novel service-oriented architecture dealing with the scalability problem leveraging the Path Computation Element (PCE) concept. PCE has already been proved as an efficient technology to decouple the control tasks from the forwarding nodes, what undoubtedly impacts on scalability growth. Given the importance of control solutions for IoT, we propose to enrich the current host-oriented PCE model to become a Service-oriented PCE (SPCE). Results obtained after running several evaluation tests show that the proposed PCE-based solution may support a higher number of Network Elements (NEs).
