Data Aggregation in Cluster based Wireless Sensor Networks

A wireless sensor network is a wireless network, in which we basically use tiny devices which monitor physical or environmental conditions at different regions. Thus the wireless sensor network basically comprises of sensing, communicating, computing, programming and control ingredients. We can design and configure sensor network applications designed that have better fault tolerance. In most applications sensor networks are deployed once and operate for a long period of time. In this respect managing and maintaining wireless sensor network becomes an important task. However, the problem of limited energy constraint presents a major challenge for the network deployment. Hence it clearly follows that in order to gather information from node to node we require data forwarding protocol. So the aim of any data forwarding protocol is to conserve energy to maximize the network lifetime. Sensor nodes are capable of performing in-network aggregation of data coming from more than one source. In this paper we have concentrated on energy consumption issue and designed energy efficient data aggregation protocol named EBINA. Thus protocol using a cluster-based wireless sensor network is more relevant. Each cluster is executed independently and thus we obtain an energy efficiently data, which finally is aggregated in a cluster by this the lifetime of the cluster is also increased. We have used Network Simulator 2(NS-2) for simulating the protocol.
