Self managed system of sensor network — an artificial ecological system

We have constructed a self-maintain system based on the concept of the artificial ecological system (AES). Under the framework of the AES, we proposed a model of ecological balancing include the sensor nodes dynamics model (SNDM), the sensor nodes ecological model (SNEM) and the population growth limit model (PGLM). The SNDM is used to implement the diffusion, and the SNEM is used to maintain the sensor nodes. The PGLM can control the sensor network density. We discussed the effect of the prey node searching and handling. With these models, we can create an ecological balance environment with automatic recharge, recycle and quantity control. It is desired to keep these sensor nodes reach the blanket coverage and maximize, two species exist and ensure they will not die out. As a result, save tremendous human resource needed and cost on this self-maintain ecological system.
