Abstract

The need of real-time data acquisition in industry control system is growing, ARM7 processor LPC2200 combined with embedded real-time operating system μc/OS-II realize the data acquisition system and remote transmission through the wireless Communication and can be used in a wider field. The overall structure of the system, the software process and acquisition hardware circuit are introduced. The whole system hardware is in the small size, low power consumption, strong scalability, stable operation, convenient program maintenance and upgrade, have many channels online real-time data acquisition, processing and transmission, and other functions.

Abstract

Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy awareness is an essential design issue. The focus, however, has been given to the routing protocols which might differ depending on the application and network architecture. Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communication capabilities. In this paper, Rapid Spanning Tree and Cluster Head Routing using we present a survey of the state-of-the-art routing technique and a novel energy efficient hybrid routing protocol. We first outline the design challenges for routing protocols in WSNs' followed by a comprehensive survey of differrmt routing techniques. Overall, the routing techniques are classified into four categories based on the underlying network structure: Data centric, hierarchical, location based and Quality of Service (QoS) based. Further, Many To One-A hybrid protocol based on Rapid Spanning Tree, (RST) and Cluster Head Routing (CHR) uses clustering, which includes partitioning stage and choosing stage, namely, partitions the multi-hop network and then chooses duster-heads; cluster-head is responsible for receiving, sending and maintaining information in its duster. Then all cluster-heads will construct a Rapid spanning tree to prolong network lifetime, save energy and shorten path. RST provides faster spanning tree convergence after a topology change, thereby minimizing the energy consumed.
