N2 - Broadcasting in wireless sensor networks (WSNs) is a basic operation to control the entire network. However, traditional broadcasting is not appropriate for WSNs with a low-duty-cycle; it is devised for an energy-limited environment, where nodes stay asleep much of the time and wake up only for a short time. Duty-cycled broadcasting methods, such as the opportunistic flooding (OF) scheme, have been studied to reduce the flooding delay. However, OF suffers a problem of energy unbalanced consumption, incurring early network disconnection. In this paper, we modify OF to decrease the broadcast delay and prolong the network lifetime, through acquiring more candidates for senders and considering the remaining energy of nodes. Simulation shows our scheme achieves shorter delay and longer network lifetime than OF (i.e., decrease by up to about 60% and increase by up to about 100%, respectively).
