Energy Balanced Routing for Data Collection in Wireless Sensor Networks

Wireless Sensor Network (WSN), is a system composed of large number of micro sensors. In most of its applications, data are typically gathered by the sensor nodes and reported to the data collection point called the sink or the Base Station (BS). The sensor nodes have limited battery power and battery replacement is not easy for these networks, with thousands of physically embedded nodes. Hence efficient use of battery is very important to maximize the lifetime of the network. And this is achieved by a tree based energy balanced routing protocol, which builds a routing tree using a process where for each round the BS assigns a root node and broadcasts this selection to all sensor nodes in the network. Subsequently each node selects its parent by considering only itself and its neighbour’s information. Thus making it a dynamic process. The comparison with the existing protocol is also performed to show the improvements.
