Abstract—Recent advances in the field of electronics and
communication leads to development of tiny battery enabled
sensor nodes. These sensor nodes are randomly deployed as a
wireless sensor network for sensing environment. Over the years,
the most important problem in wireless sensor network is to
develop a routing protocol that maximize the life time of
network. Each node in a sensor network becomes useless after
wasting its energy completely because its power totally depends
on the embedded battery. So we should employ the routing
protocols which can consume the energy of nodes efficiently.
Many protocols for energy efficient routing in sensor networks
have been suggested but LEACH and PEGASIS are most
well-known protocols based on Clustering. However LEACH
consumes energy heavily in the head nodes and the head nodes
tend to die early and PEGASIS - which is known as a better
energy efficient protocol has a long transfer time from a source
node to sink node. We proposed a new three stage routing
protocol which combines LEACH and PEGASIS. And we
introduced the concept called Cluster Head Set which is
responsible for transferring the data. The Headed selection is
similar to LEACH. In addition to Header Head set members are
selected. The Data forwarding technique is similar to PEGASIS.
The Simulation Results shows that this protocol consumes the
energy of the node efficiently and improves the life time of the
Network and also it reduces the redundant transmission of the
data. For set of 100 Nodes the proposed algorithm gives 50
percent better performance than LEACH and 6 percent better
performance than PAGASIS in terms of network life time and
also it gives 61 percent better performance in terms of
