Hierarchical Energy Efficient Routing Protocol (HEERP) for Wireless Sensor Networks (WSN)
Wireless sensor network consists of an enormous number of small disposable sensors which have limited energy. These sensors cannot be replaced once they are deployed, as the users usually have no access to these nodes. In many situations like battle field monitoring, rescue operations, the battery operated nodes usually have no accessibility and thus its battery can't be replaced. Hence, energy efficiency is the key research question in wireless sensor networks that is required to be fingered sensibly in order to prolong or improve the life time of the network. An extensive amount of energy is consumed during routing operations; because of this it is the hottest research area in WSN.
