Abstract
This paper considers large-scale dense wireless sensor networks with path-constrained mobile sink. From the viewpoints of improving data equilibrium and energy-saving, we propose an enhanced energy efficient communication protocol in which a partition algorithm of overlapping time based on data equilibrium is designed to minimize the data variance and disequilibrium from each node. We present a data equilibrium information diffusion method to control the amount of collected data to avoid the waste of data and energy. Simulations under OMNET++ and MATLAB show that with protocol and algorithms proposed in this paper we can achieve better performance than other conventional methods in terms of data equilibrium rate, network lifetime and energy dissipation equilibrium rate.
