CHAPTER 1INTRODUCTION TO WIRELESS SENSOR NETWORKS This Chapter briefs the challenges and mechanisms of WirelessSensor Networks. Various Routing and MAC Protocols related to WSN areanalyzed in this Chapter. Some important applications of WSN are also revealedin this Chapter.1.1 INTRODUCTIONA Wireless Sensor Network (WSN) consists of spatially distributedautonomous sensors to monitor physical or environmental conditions, such astemperature, sound, pressure, etc. and to cooperatively pass their data throughthe network to the main location. On the other hand, modern networks are bidirectional, also enabling control of sensor activity. The development ofwireless sensor networks have been used by military applications, industrialand consumer applications, such as industrial process monitoring and control,machine health monitoring, and so on.
