“…It envisions an era of pervasive applications that are built on top of these networked devices. [5]. Other technical issues of DPWS have also been explored such as encoding and compression [6], the integration with IPv6 infrastructure and 6LoWPAN [7,8], the scalability of service deployment [9], and the security in the latest release of WS4D DPWS stacks.…”

“…Instead, it relies on SOAP-over-UDP 4 binding and UDP multicast to dynamically discover device services. DPWS offers a publish/subscribe eventing mechanism, WS-Eventing 5 , for clients to subscribe for device events, e.g., a device switch is on/off or sensing when temperature reaches a predefined threshold. When an event occurs, notifications are delivered to subscribers via separate TCP connections.…”

The OASIS standard Devices Profile for Web Services (DPWS) enables the use of Web services for service-oriented and event-driven Internet of Things (IoT) applications. DPWS has been proven to be an appropriate technology for implementing services on resource-constrained devices. However, the performance of these services has not been well investigated to realize DPWS features such as dynamic discovery and eventing mechanisms for IoT scenarios. Moreover, DPWS introduces considerable overhead due to the use of Simple Object Access Protocol (SOAP) envelopes in exchange messages. We extend the DPWS standard by using a Representational State Transfer (REST) proxy to tackle these problems, creating RESTful Web APIs to pave the way for developers to invest more in this technology.

“…Resources can again have multiple sub-resources, which can also be added dynamically. Figure 2b illustrates a subset of our demonstration server 8 . The framework also provides a stub to handle the creation of resources via PUT when resources along the path do not exist at the time the request is received.…”

“…The Devices Profile for Web Services (DPWS) initiative defined implementation constraints for SOAP Web services so they can be used in machine-to-machine communication that is more constrained than server systems. Current research in this field targets the adaptation of DPWS for highly resource-constrained devices like the Tmote Skys used in our architecture [8].…”

Abstract-Unlike traditional networked embedded systems, the Internet of Things interconnects heterogeneous devices from various manufacturers with diverse functionalities. To foster the emergence of novel applications, this vast infrastructure requires a common application layer. As a single global standard for all device types and application domains is impracticable, we propose an architecture where the infrastructure is agnostic of applications and application development is fully decoupled from the embedded domain. In our design, the application logic of devices is running on application servers, while thin servers embedded into devices export only their elementary functionality using REST resources. In this paper, we present our design goals and preliminary results of this approach, featuring the Californium (Cf) CoAP framework.

“…Many research papers have analyzed the impact that both architectures would have on WSNs. Results from [8] and [9] show that the overhead of the messages exchanged between SOAP Web services is higher than that of RESTful Web services. In fact, SOAP messages are encapsulated in the XML body, which involves a complex and expensive message processing.…”

Abstract:In this paper we present the design and implementation of the Constrained Application Protocol (CoAP) for TinyOS, which we refer to as TinyCoAP. CoAP seeks to apply the same application transfer paradigm and basic features of HTTP to constrained networks, while maintaining a simple design and low overhead. The design constraints of Wireless Sensor Networks (WSNs) require special attention in the design process of the CoAP implementation. We argue that better performance and minimal resource consumption can be achieved developing a native library for the operating system embedded in the network. TinyOS already includes in its distribution an implementation of CoAP called CoapBlip. However, this is based on a library not originally designed to meet the requirements of TinyOS. We demonstrate the effectiveness of our approach by a comprehensive performance evaluation. In particular, we test and evaluate TinyCoAP and CoapBlip in a real scenario, as well as solutions based on HTTP. The evaluation is performed in terms of latency, memory occupation, and energy consumption. Furthermore, we evaluate the reliability of each solution by measuring the goodput obtained in a channel affected by Rayleigh fading. We also include a study on the effects that high workloads have on a server.
