Abstract : WSN (Wireless sensor network) is composed of a large number of small, inexpensive, energy constrained nodes that are used to sense data for various civil and military applications. The sensed data from the environment is then propagated using various routing techniques to the base station. A sensor node becomes useless once its energy source i.e. the battery gets used up. To increase network lifetime, the main issue in wireless sensor networks is of energy conservation due to the fact that sensor nodes are kept in conditions and places that are inaccessible and left unattended. Network lifetime and energy conservation depends on using efficient routing techniques in wireless sensor networks, since energy is mostly used in transmission and reception of radio signals. Researchers have proposed many efficient routing protocols that can lower the energy consumption and thus increase the network lifetime. In this paper, we provide a comparative study of some popular cluster based hierarchal routing protocols using analytical simulation in MATLAB.
