Internet of Things envisions some services that require both end-device mobility and high availability or high bandwidth. However, the current environment with a cellular network and single-path protocols may not guarantee a sufficient service level. Thus, this study evaluates the economic feasibility of using multipath protocols for increased availability and bandwidth when contracting with several cellular operators. By using cost-efficiency analysis, a model is developed for comparing multipath protocols with their singlepath alternatives. The usage of the model is demonstrated with two potential mobile application scenarios that could benefit either from increased availability or bandwidth. Finland is used as an example market. The benefits of multipath protocols were quantified with an extensive set of handset-based measurements from Finnish cellular networks. The results of this study indicate that the initial costs of a multipath infrastructure remain relatively small, and the total costs rapidly approach the operational costs as the number or active time of smart devices increase. Therefore, this study indicates that multipath protocols are economically feasible for certain mobile Internet of Things applications, particularly those requiring high bandwidth. Thus, new service models emerging in the Internet could create a real demand for multipath protocols in the future.

“…CoAP also consumes less power and is easier to configure for constrained devices than HTTP [4]. These benefits translate into cost advantages especially in the application scenarios where the smart objects i) are large in volume and/or are deployed in distant locations, ii) communicate frequently over links with volume-based charging, and iii) are sleeping between the communication sessions [9]. On the other hand, CoAP is still under development and its deployment is minimal compared to HTTP.…”

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.

“…We looked for any work on implementing WS-Security on Arduino, ESP8266 or Atmel systems (which are common targets for IoT device implementations) without success. XML performance on small devices can be improved using Efficient XML Interchange (EXI), which reduces network traffic (Levä, Mazhelis & Suomi, 2014).…”

“…In Levä, Mazhelis & Suomi (2014) there is comparison of using Constrained Application Protocol (CoAP) with EXI against HyperText Transfer Protocol (HTTP), showing efficiency gains in using CoAP. In Nicholas (2012), MQTT over TLS is shown to use less power than HTTP over TLS in several scenarios.…”

The rapid growth of small Internet connected devices, known as the Internet of Things (IoT), is creating a new set of challenges to create secure, private infrastructures. This paper reviews the current literature on the challenges and approaches to security and privacy in the Internet of Things, with a strong focus on how these aspects are handled in IoT middleware. We focus on IoT middleware because many systems are built from existing middleware and these inherit the underlying security properties of the middleware framework. The paper is composed of three main sections. Firstly, we propose a matrix of security and privacy threats for IoT. This matrix is used as the basis of a widespread literature review aimed at identifying requirements on IoT platforms and middleware. Secondly, we present a structured literature review of the available middleware and how security is handled in these middleware approaches. We utilise the requirements from the first phase to evaluate. Finally, we draw a set of conclusions and identify further work in this area.
