Design Model and Deployment Fashion of Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSN) play a critical role in Internet of Things (IoT). It is essentially the interface between the IoT and the physical world. This chapter describes the characteristics of the WSN and analyzes the power constraints, the network operation, the operating system, and the computing paradigm resulted from these characteristics. IoT needs High-Performance Computing (HPC) to resolve its optimization problems. How to efficiently use the embedded, distributed, or hosted computing power in IoT is the fundamental principle of addressing the challenges in constructing a smart world. New approaches to HPC are made possible by advances in microprocessor architectures which include proliferation of parallelism and high-bandwidth networks. Several solutions exist, such as Graphics Processing Unit (GPU) computing, Many Integrated Core (MIC) computing, heterogeneous computing, Peer-to-Peer (P2P) computing, Cloud computing, and Grid computing. The chapter discusses two operating systems that are emerged in the research of sensor networks, including TinyOS and LiteOS.
