In wireless sensor networks, it is necessary to collect information from sensors using less energy. Therefore, it is proposed that representative sensors called a head collect information from neighbors and send it to a base station. The problem is how to decide heads autonomously. In a grid network, it is known that a method using pattern formation by a reaction-diffusion (RD) system is useful. However, energy efficiency is not so good, because locations of heads are fixed. In this paper we propose a method for deciding heads using pattern formation of a cellular automaton (CA). By computer simulation, we show that our method is less energy consumption than the method using the RD system.
