The problem of energy-balanced data transmission in sensor network is studied extensively in this paper. Energy Balance assures uniform energy dissipation among all the nodes in the sensor network. Uniform energy dissipation guarantees same average energy dissipation per node throughout the network. This enables the network to be fully functional for the maximum time, avoiding the early energy depletion of sensor nodes. Previously proposed models in the literature though theoretically proves the balance, we here propose a practical Energy-Balanced Transmission (Adaptive AODV) model which gives the required balance by transmitting packets as a combination of direct transmission to Base Station (an expensive) and multi-hop transmission towards Base Station (a cheaper), independent of routing protocol. In this paper the model is studied thoroughly, tested and simulated using ns2 simulator. Adaptive AODV is validated and analyzed through simulation results in reactive ad hoc routing protocols. The comparative results show the uniform energy utilization, and the flexible approach of the model.
