Durin: A development environment for Wireless Sensor Network

The applications for Wireless Sensor Networks (WSN) have simple functional requirements, which basically consist of reading the sensors, and sending the read data to the application. However, when non-functional requirements are taken into account, developers of applications for WSN have to deal with such requirements as: restrictions on the consumption of energy, dynamic applications update due to poor performance or unexpected behavior, dynamism in network topology, scalability, robustness, QoS, heterogeneous hardware sensors and limited bandwidth. All these constraints turn the creation of an application into no trivial task. With that in mind, the purpose of this paper is to present a development environment for WSN to improve developer productivity. The Durin development environment is composed of: TinyReef, a designed virtual machine (VM) for WSN; a compiler for cited VM instructions; and a Remote Application Manager. The main contribution of Durin is to provide an environment to support the development, maintenance and deployment of applications for WSN, enabling remote application updates of sensor node hardware.
