AbstractSensor networks are specially constructed networks for collecting data from sensor nodes and delivering it to sink nodes at the end. Each nodes in a sensor network are small embedded systems, which require wireless communication among them with limited hardware constraints. If programmers develop sensor network applications for a large-area sensor network, the development of application will be very difficult without any support of operating system. Therefore, we developed a small operating system, referred to as NanoQplus, to enable to build a large-scale sensor network application rapidly and efficiently. NanoQplus is a multi-threaded, lightweight and low-power sensor network operating system. Although multi-threaded operating systems in sensor nodes need to manage multiple stacks to prevent the stack overflow problem, NanoQplus gives an elegant solution with a memory protection mechanism. This paper describes all about NanoQplus technologies; a philosophy, design issues, architecture, supported software products and NanoQplus programming style.
