Are required increasingly to a mobile sensor node

In various applications of sensor networks, monitoring is required after the event is an important issue of concern is that the incident took place, there is no location information for  mcb circuit breaker  message is meaningless. With the development of wireless sensor network technology, more and more applications require sensor nodes have mobility. Although wireless sensor network localization algorithm has been a electri cenergy meter , but  electric meter  for the mobile node localization algorithm not more. This paper introduces the basic concepts of wireless sensor networks, architecture and its application; On this basis, further information on the wireless sensor network node localization related concepts.
