Nano-kernel: A Dynamically Reconfigurable Kernel for WSN

Abstract

The Wireless Sensor Networks (WSN) have received considerable research attention in recent time. The sensor devices of a WSN are severely resource constrained having a very limited operational lifetime. Such sensor devices have to adapt to the changing environment at deployment site and need dynamic reconfiguration. The operating systems supporting the sensor devices should be capable of realization of dynamic reconfiguration at kernel level as well as at application layer. This paper proposes a design framework of nano-kernel, a lightweight operating system for sensors. The proposed nano-kernel architecture incorporates dynamic reconfiguration capability by decoupling the kernel data objects from the policies implemented in the kernel subsystems. Based on the modular design approach, an implementation direction is outlined.

“…In terms of functionality, software and protocol reconfiguration can support various scenarios at runtime. For most networks, reconfiguration can be implemented by dynamic reprogramming [3,4] or the loading of different components [5].…”
