Challenges in Mobile Sensor Networks: A Survey

PhD Qualifying Examination


Title: "Challenges in Mobile Sensor Networks: A Survey"

Mr. Ji Luo


Abstract:

The growing technique of mobile sensors has enabled many new applications
in wireless mobile sensor networks such as sea monitoring, animal
migration and patrol defense. Unlike existing wireless sensor networks
which are composed of static sensors, mobile sensor networks have a new
feature of sensor mobility -- sensors are moving all the time. In this
survey, we demonstrate that sensor mobility makes a great impact on most
existing protocols of wireless sensor networks. We provides an overview of
challenges in mobile sensor networks from three aspects: challenges for
localization in mobile sensor networks, challenges for providing coverage
services by mobile sensor networks and challenges for data collection in
mobile sensor networks. By dividing the mobile sensors into two types:
controllable sensors and uncontrollable sensors, we analyze the advantages
which can be exploited from controllable sensors and the uncertainty
brought by the uncontrollable sensors. This survey shows that sensor
mobility brings a lot of challenges in mobile sensor networks but on the
other side, it also provides big opportunities that we can leverage the
sensor mobility to help in improving many protocols such as localization,
coverage and data collection.
