Mobile sensors in wireless sensor network cyber-physical systems

To overcome the problem of coverage and efficient data management, mobility in wireless sensor networks (WSNs) has been attracting a lot of attention in recent years. WSN are also an integral part of cyber-physical systems (CPSs) because of their strong sensing ability. CPSs are considered to be an emerging technology, and there are many challenges that need to be addressed to enable the flexible integration of the cyber and physical domains. We present a survey of mobile WSN-CPS approaches that have been proposed to date, along with a mobile WSNCPS application classification. The mobile WSN-CPS applications are then compared to highlight the similarities in and differences between the state-of-the-art technologies used in mobile WSN-CPS. We have also identified the areas of mobile WSN-CPS that require further research in the future.
