Embedded Software Design for WSNs

Abstract

This chapter introduces the software design for WSNs, including sensor driver design, network initialization and establishment, network management, and data transmission and reception. The embedded software architecture for WSNs is given with the Jennic ZigBee and the Contiki 6LowPAN as two examples. Examples of both analog and digital sensor driver developments are introduced. The implementation of establishing WSNs is illustrated by adopting an IEEE 802.15.4 stack rather than a Zigbee stack for the generality.
