A novel self-maintenance ecological system of sensor network based on ecological balance environment

In this paper, we have constructed an artificial ecological system (AES) used to manage sensor´s behaviour and maintain sensor network. We have defined two kinds of species for sensor nodes, one is called prey and the other is called predator. It is desired to keep these sensor nodes reach the blanket coverage and maximize, two species exist and ensure they will not die out. We use two methods namely self-deployment and self-maintenance. The sensor nodes dynamics model (SNDM) based on the molecular dynamics is used to implement the diffusion, and the sensor nodes ecological model (SNEM) is used to maintain the sensor nodes. With these two models, we can create an ecological balance environment with automatic recharge, automatic recycle and automatic quantity control.
