Abstract— A wireless sensor network contains a set of
sensor devices that are usually operating on battery power with
a limited energy resources and due to the dimensionality of these
networks, replacing the batteries is a complicated task. Thus
energy efficiency is one of the most important issues and
designing energy efficient protocols is critical for prolonging the
lifetime. This paper introduces a two routing protocols namely,
LEACH and EAMMH in Homogenous & Heterogeneous system
supported by simulation scripts, and analysis of the results
against known metrics with energy and network lifetime
being major among them. Simulation results using MATLAB
shows that the proposed EAMMH in Homogenous &
Heterogeneous system significantly reduces energy consumption
and increases the total lifetime of the wireless sensor network. |
