Wireless sensor networks(WSNs) has received a
lot of attention in recent years due to their wide spread
applications like military, disaster surveillance, wildlife
observation, agriculture smart homes, etc. Sensor nodes are
usually deployed randomly in a physical environment to
monitor and transmit their collected data to a remote sink
node (base station). The base station is fixed and has
continuous power supply whereas sensor nodes are powered
with limited batteries and cannot be easily recharged once
deployed. Therefore energy efficiency and balancing the
network is one of the primary challenges to the successful
application of WSN. In this paper we compare different
protocols to check the energy-efficiency of the sensor
network. We propose an inner-cluster data aggregation
scheme, where in a cluster only selected nodes will transmit
the data to the cluster head for further data processing. This
reduces the energy wasted by many nodes in transmitting
the redundent data to base station. It also reduces the
energy and time involved in reducing the redundent data.

In this paper we propose a data aggregation scheme to
reduce inner cluster transmission, which in turn increases
the energy efficiency of the network. The CH will be
selected dynamically, and three nodes with in the cluster
were selected to transmit the collected data to the CH at a
time interval. This saves lot of energy used in data
transmission. It also reduces a lot of redundent data at the
BS. Thus lowers the communication overhead and
prolongs network lifetime.
