Wireless sensor monitoring systems

Wireless sensor networks are finding their applications in many diverse fields. The design of components of these systems such as sensor nodes, protocols, and architecture differs based on the application for which these networks are used. Some of the applications need data collected by the sensors to be sent immediately to the coordinator without being concerned about the energy used, whereas other applications require energy to be conserved as long as delayed transfer of data is acceptable. Most of the studies till now have focused on proposing a design for specific applications. Given that we are experiencing a steady increase in the number fields where wireless sensor networks are being applied, we feel it is not necessary to propose a design for every new application. Instead we plan to categorize these applications—whether old or new—into different classes of applications and propose a design for them. We do this categorization based on common characteristics and requirements. In this work, we group various applications of sensor networks as systems and propose a system design—nodes, protocols and architecture—for each of the wireless sensor monitoring systems.;Key words. Wireless sensor network, architecture, system design, sensor applications.
