| Summary: | Recently, heterogeneous wireless sensor network
(HWSN) routing protocols have drawn more and more attention.
Various HWSN routing protocols have been proposed to improve
the performance of HWSNs. Among these protocols, hierarchical
HWSN routing protocols can improve the performance of the
network significantly. In this paper, we will evaluate three
hierarchical HWSN protocols proposed recently—EDFCM, MCR,
and EEPCA—together with two previous classical routing protocols—LEACH and SEP. We mainly focus on the round of the first
node dies (also called the stable period) and the number of
packets sent to sink, which is an important aspect to evaluate the
monitoring ability of a protocol. We conduct a lot of experiments
and simulations on Matlab to analyze the performance of the five
routing protocols. |
