A detailed survey on Bandwidth efficient cluster based routing schemes in wireless sensor networks

Wireless sensor networks for military operations, ground surveillance and more are widely used. As each sensing device has batteries, the energy consumption effectiveness in the network is a real time problem which depends on the placement of each sensing device. Many of the existing procedures use gathering techniques to measure power consumption between sensing devices by collecting information. A cluster consists of several sensor nodes, one of which is a head of the cluster. The information collected by the head cluster from all other members is transmitted to the main station. The important function of the WSN protocol is to transmit this discovered information to the BS.
