A comparative analysis of wireless sensor network operating systems

Abstract

Wireless sensor networks are composed of large numbers of tiny networked devices that communicate. Many sensor networking applications such as surveillance and environmental monitoring are time-sensitive in nature. Two different operating system types are currently considered for sensor networks: event driven and multithreaded. The Operating systems employed for WSN (wireless sensor networks) are either satisfied with only one or two application classes or unsuitable for strict-constrained resources. In view of a variety of WSN applications, there is a need of developing a self adaptable and self-configurable embedded real-time operating system (RTOS). In recent years, the availability of cheap and small micro sensor node and low power wireless communication give a contribution of enhanced developments of wireless sensor network application in real society. A light-weight embedded resource kernel with rich functionality and timing support is practical and constitutes a simple and alternative paradigm for supporting distributed sensing tasks. This paper we will make a comparative study of various operating systems related to wireless sensor network.
