Abstract

This paper developed an improved hybrid – low energy adaptive clustering
hierarchy (Hybrid - LEACH) protocol for wireless sensor networks (WSNs). In
order to effectively utilize the network energy, a residual energy level of cluster
head (CH) and threshold energy value were used in determining if a CH head
should be changed or continue after a round. The base station (BS) calculates
and sets the threshold energy based on the network energy map using predictive
approach. The simulated results in MATLAB 2015b showed 99.78% packet
delivery success, the first sensor node (SN) died after 1600 rounds and the last
sensor node in the network died after 6400 rounds. The developed system when
compared with hybrid –leach protocol had a 33% improvement in terms of
network before the death of the first SN and 63.77% before the last node in the
network died.
