In this paper, a mobile wireless sensor network (MWSN) is introduced for the purpose of worker’s safety. Public authorities and Standard Committee sets the limit for the emission of dust, noise and other harmful agents based on the previous examination of endangerment for worker’s and resident’s health as well as environment. While emission crosses the threshold limit, the mobile sensor nodes send notifications to the operator, then the user can react to this information and takes quick action. For tracking the workers within the limited site, IOT based WSN network is widely used.
