OPTIMIZATION OF LEACH PROTOCOL BASED ON A GAME THEORY CLUSTERING APPROACH FOR WIRELESS SENSOR NETWORKS

Abstract:

Wireless sensor network clustering has been regarded as the efficient mechanism for collecting the sensor nodes data to the sink, using the topology division technique into clusters. Each group elects a cluster head CH responsible for data aggregation. However, due to the waste of energy, the nodes refuse to declare itself as a cluster head, and it behaves like a selfish and non-cooperative node. In this paper, we will propose a mathematics game theory analysis and evaluation willing improve and optimize the CH selection algorithm on the LEACH protocol.
