Abstract

Abstract: In wireless sensor network (WSN), to effectively balance energy of nodes and prolong survival time of the network is a key problem. To solve the problem, this paper proposes an algorithm named cluster control based on low energy adaptive clustering hierarchy (CC-LEACH) based on LEACH. Using this algorithm, cluster heads are selected by the sink. Simulation results show that the method has advantages in terms of energy balance and network lifespan.

Key words: funnel effect, energy balance, low energy adaptive clustering hierarchy (LEACH), wireless sensor network (WSN)
