Study Of WSNs: Its Application and Types

Recent years have witnessed the power of WSNs as a most secure network communication medium. Among that a wide
varieties of sensor networks and their variants have found their application and uses. The development of wireless sensor
networks was motivated by a number of military applications such as battlefield surveillance along with a lot more areas
of life. The design of a WSN depends significantly on the application, and it must consider factors such as the
environment, the application’s design objectives, cost, hardware, and system constraints. There are many Size and cost
constraints on sensor nodes that result in constraints on resources such as high speed. energy, good memory, and
communications bandwidth. This has been enabled by the availability, particularly in recent years, of sensors that are
intelligent and cheaper. These sensors are made with wireless interfaces through which they can communicate with one
another to form a network. The goal of our survey is to present a comprehensive review of lot of works done on Wireless
Sensor Networks.
