Data Transmission Techniques for Mobile Sensor Networks

In mobile sensor networks (MSNs), since sensor nodes and wireless networks are highly resource constrained and, it is highly required to manage sensor data in flexible and efficient manners. Under the MEXT research project The Grand-in-Aid for Scientific Research (S)(21220002) of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), Japan entitled "Studies on Efficient Data Processing Techniques for Mobile Sensor Networks," we have conducted researches on data management issues in MSNs. In this paper, we report some of our achievements in a sub-area of this project, which addresses data transmission for efficient data collection in MSNs. In particular, we first show our achievements on how to efficiently transmit sensor data from sensor nodes to mobile sink nodes considering the fairness and the amount of sensor data collected. Then, we also show our achievements on how to enlarge sensor data collection area and how to reduce communication traffic using mobile sink nodes.
