Abstract – In this paper an improve Energy aware
distributed unequal clustering protocol is projected. The
protocol is used for solving energy- hole problem in multi-
hop wireless sensor network. In clustering parameters we
have location of base station and residual energy. Based
on these parameters, different competition radii are solve
to node. In this protocol, by electing cluster heads
considering number of nodes in the neighborhood in
addition to the above two parameters. We are comparing
two protocols. The inclusion of the neighborhood
information for computation of the competition radius
provides better balancing of energy in comparison with
the existing approach. Therefore, the selection of next
node, the relay metric is defined directly in terms of energy
expense instead of only the distance information Used in
the protocol and the data transmission phase has been
extended in every round by performing the data collection
number of times through use of major slots and mini-slots.
The methodology used is same clusters for an every rounds
and is effective in reducing the energy consumption.
The performance of the proposed protocol has
been calculated three different scenarios and compared
with protocols through simulations. The results show that
the proposed protocols in terms of network lifetime in
every scenarios.

1. INTRODUCTION
A wireless sensor network consist of many small, light
weighted, low cost wireless nodes. These nodes are
randomly distributed at a remote location to sense
physical data such as: Temperature, Humidity, Vibration,
Pressure and Noise etc.
Lot of research work has been carried out in
the last decade to address this challenge [1-3].WSNs are
deployed for data gathering applications involving a
large amount of area such as agriculture, forests , coal
mines, monitoring of rail tunnels, etc. The base station is
placed far away from the sensing filed in most of the
cases. Data are gathered periodically by the base station.
Clustering is the most of the technic to monitoring the
networks [7-11]. Network offers greater lifespan the
network with direct data transmission. It improve the
lifespan gets improved by the factor of about 2 or 3 times
with clustering [12].
There are many uses of clustering protocols in
data aggregation networks. In bored network, usually
there is large volume of traffic among the sensors, which
leads to certain of interference and subsequently results
into collisions. Clustering the sensors would minimize
the number of long distance transmission and there
result into saving of the energy. When the normal sensor
node sleep times are drawn out, while cluster head
coordinates the activities of its members nodes again
resulting into energy saving [13]. This activity is
executed TDMA based protocol [5, 11, 14, and 15]. Data
aggregation at cluster head by the lower number of
transmitted data packets, which helps reduction of the
energy consumption of sensor nodes.
The clustering protocol has two steps, first is
intra cluster that means within the clusters, and second
is inter cluster, that means cluster to base station.
Clustering depends on single hop transmission or multi-
hop transmission [16, 17].
First clustering protocols use single hop
communication for communicating inside the cluster, as
the distance between sensors within the cluster. E.g.
LEACH [11], LEACH-DT [15], HEED [18], etc. But our
report based on Multi-hop communication between
sensor nodes and cluster head. Sensor node and the
cluster head is more energy efficient than single hop
communication, when the propagation loss exponent is
high. Multi-hop examples are LEACH [22], EADC [23],
EDUC [24], etc.
Recently, much research has been carried out to
address energy imbalance and mitigates energy hole
problem for clustered WSNs. Number of strategies such
as using node mobility[25,26], mobile sink, hierarchical
deployment, non-uniform clustering, data compression
and traffic aggregation etc. have been prosed for solving
energy hole problem.
