Extending the Lifetime of Wireless Sensor Networks using a Genetic Model for Defining Mobile Sinks
Cristiano M. Silva · International Robotics & Automation Journal · 2017
Mobile Sinks has been widely used in Wireless Sensor Networks (WSNs) to increase the network lifetime, especially to distribute energy consumption among the nodes composing the network. The development of low cost multi-copters, capable of autonomous flights, turns this type of vehicle into a promising solution for acting as mobile sinks. This work presents a new approach to the problem of routing multi-copters to collect data in WSNs in order to extend the network lifetime. We consider that each multi-copter is allowed to stop in a pre-defined number of points (locations) within a monitored area for collecting data from sensors. We propose a genetic model that shows how the distribution of the nodes workload can extend the network lifetime. Simulations are performed to adjust the parameters of the model, and also to evaluate the performance of the proposed strategy.
