ENERGY EFFICIENT ROUTING PROTOCOL AND DATA AGGREGATION IN WIRELESS SENSOR NETWORK

Abstract

There are so many applications where Wireless sensor networks (WSNs) can be used like tracking, monitoring etc. As we know WSNs have immense prospective and are deployed in various application of environments, but there are some restrictions as the sensor nodes have limited processing power, limited battery capability, limited bandwidth for communication and limited memory partition. WSNs contain battery powered nodes where replacement of nodes is impractical. Routing protocols in WSNs aim to increase total life time of network and energy used by the sensor nodes. Lots of work has been done on how to increase the energy efficiency of the WSNs. Clustering techniques are used to increase total life time of network. It minimizes total transmission cost and redundancy of data. Sensor nodes transmit the data towards their cluster heads. Further they collect the data and transmit it towards the base station. Clustering also enhances the stability time period for the network which is the period till all the nodes are alive in the network. Various data aggregation techniques have been proposed to increase the network life time. Thus clustering and data aggregation are important techniques to increase total life time the network. In this thesis we consider heterogeneous networks to evaluate the performance of proposed energy efficient clustering and data aggregation technique. Our goal is to reduce the energy use and increase the life time and stability of network.
