Self-adapting Data Gathering Scheme for Mobile Sink Node
Yuelin Du · 2012
Mobile sink for wireless sensor network is an efficient way to prolong the network lifetime.We studied a scenario where the mobile sink node is located in a quadcopter which is in charge of data gathering from the wireless sensor network.After analyzing the properties of mobile sink node during flying,we gave the theoretical constraints for the mobile sink node in terms of mobile trace,velocity and height for the low power wireless communication.According to these constraints,we proposed the data amount-based local optimal mobile trace control approach for the mobile sink node,so as to gather from the sensor network efficiently.Explicit simulations show that the proposed approach is feasible,which provides a theoretical basis for such applications.
