contribution of wireless sensor networks in domestic and hostile environment

Wireless sensor networks are considered to be among the most rapidly evolving technological domains thanks to the numerous benefits that their usage provides. as a result, from their first appearance until the present day, wireless sensor networks have had a continuously growing range of applications. the purpose of this article is to provide an up-to-date presentation of both traditional and most recent applications of wireless sensor networks and hopefully not only enable the comprehension of this scientific area but also facilitate the perception of novel applications. in order to achieve this goal, the main categories of applications of wireless sensor networks are identified, and characteristic examples of them are studied. their particular characteristics are explained, while their pros and cons are denoted. next, a discussion on certain considerations that are related with each one of these specific categories takes place. finally, concluding remarks are drawn.
