ABSTRACT: In this paper, we have proposed an energy efficient chain based
protocol which is an improvement over ECBSN (Energy Efficient Chain Based Sensor Network). ECBSN protocol has certain
deficiencies like the non optimal selection of leader nodes in rounds,
aggregation and transmission of data by head nodes that leads to unbalanced
energy consumption. Aiming at these problems, an improved chain based protocol is
proposed. IECBSN adopts a new method of selection of leader nodes based on
selection value (SV) parameter .To lower energy consumption further, one more
level of hierarchy has been added with a head leader node, which will aggregate
data from the leader nodes and pass it to the base station. IECBSN shows an
improvement of 20% - 35% as compare to PEGASIS (Power Efficient Gathering in Sensor
Information System) and 5% t to 7% from ECBSN on energy consumption and
improves network lifetime.
