H-LEACH: Hybrid-low energy adaptive clustering hierarchy for wireless sensor networks

Wireless sensor networks are one of the fast growing technologies in communication field, because of their compact size and ability to work in rugged conditions where human reach is not possible. This paper discusses about H-LEACH, which is used to solve problems of energy considerations while electing a channel head. H-LEACH considers residual and maximum energy of nodes for every round while electing a channel head using threshold condition. H-LEACH is compared with LEACH and HEED protocol, and proved that it is efficient than both methods. Simulations for LEACH, HEED and H-LEACH are done using MATLAB.
