A data collection traffic pattern is 3 assumed, where all sensor nodes perform periodic sensing and forwarding of data to a centralized 4 base station (sink). Under these assumptions, the effect of overhearing dominates the energy 5 consumption of the nodes. The proposed scheme achieves lifetime improvement by reducing 6 the energy consumed by overhearing and also by dynamically balancing the lifetimes of nodes. 7 Performance evaluations are presented from experimental studies as well as from extensive 8 simulation studies to show the effectiveness of the proposed scheme. 9
