Its-light: Adaptive lightweight scheme to resource optimize intelligent transportation tracking system (ITS)-customizing CoAP for opportunistic optimization

Abstract

In this paper we aim to reduce overall resource usage and improve throughput of an intelligent transportation tracking application. Primary improvements in terms of bandwidth and latency are achieved using CoAP (Constrained Application Protocol). We propose a novel approach to adapt CoAP’s reliability mode for data transfer by inferring vehicle’s motion-state from tracking information. Further, we make salient modifications in protocol to achieve even better optimization and improved throughput and scalability while using non-reliable data transfer mode of CoAP. Proposed scheme is analyzed based on results obtained both in real and emulated environments.
