In this paper, an inter-cluster data aggregation based on General Self-Organized Tree-based Energy Balance (GSTEB) routing protocol has been improved by proposing energy efficient protocol under hybrid soft computing. First, finest cluster heads are elected by using enhanced ant colony optimization (ACO) method. After that, information which has been gathered by cluster heads is sent to sink node by applying hybrid soft computing (i.e., hybridization of glow swarm and ACOs). Experimental analysis shows that network lifetime has been improved according to the proposed procedure in contrast with already available procedures.
