Hi
In this paper, we recommend a multi-chain model of
PEGASIS along with induction of sink mobility to
maximize the network lifetime. Our considerations are
supportive in diminishing the delay in data delivery and
distances between the connected nodes through smaller
chains. Sink mobility not only lessens the load on the
chain leaders in starting rounds, but also reduces the
stress on the sparse nodes at the end of network lifetime.
We also propose an algorithm for fixed path sink mobility
in our model. Sink mobility has major advantages on static
sink in enhancing the network lifetime. As for future
directions, we are striving to get much better sink mobility
specifically toward chain leaders of chains in WSN.
