Constrained Application Protocol (CoAP) has been developed as an alternative to the HyperText Transfer protocol (HTTP) to connect resource-limited devices to the Web. In addition to technical advantages, the success of Internet protocols depends also on their economic feasibility for the stakeholders involved in protocol deployment. Therefore, this paper studies the techno-economic feasibility of CoAP by applying a methodological framework. Based on literature review and nine expert interviews, the paper identifies potential deployment challenges of CoAP and suggests solutions to them. The results can be used to facilitate the deployment of CoAP and to guide the potential adopters in decision-making.
Among billions of Internet enabled devices that are expected to surround us in the near future, many will be resource constrained, i.e., will have limited power supply, processing power and memory. To cope with these limitations, the Constrained Application Protocol (CoAP) has been recently introduced as a lightweight alternative to HTTP for connecting the resource limited devices to the Web. Although the new protocol offers solid technical advantages, it remains uncertain whether a successful uptake will follow, as it depends also on its economic feasibility for the involved stakeholders. Therefore, this paper studies the techno-economic feasibility of CoAP using a systematic methodological framework. Based on eleven expert interviews complemented with a literature survey, the paper identifies potential deployment challenges for CoAP, both technical and business-related, and suggests approaches to overcome them. The findings should facilitate the uptake of CoAP by supporting the potential adopters of the protocol in their decision-making.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
