Towards a Resilient Operating System for Wireless Sensor Networks

Hyoseung Kim and Hojung Cha, Yonsei University


Active research has recently been conducted on large scale wireless sensor networks, especially network management and maintenance, but the technique for managing application errors on MMU-less sensor node devices has not been seriously considered. This paper presents a resilient operating system mechanism for wireless sensor networks. The proposed mechanism separates the kernel from the user execution area via dual mode operation, and the access violation of applications is controlled by static/dynamic code checking. The experiment results on a common sensor node show that the proposed mechanisms effectively protect the system from errant applications.
