Networks that are dynamically formed by hundreds or thousands of inexpensive sensors are widely used in environmental monitoring, disaster recovery and the other domains. In this paper we present a protocol, LM-PB, for on-line broadcast routing in wireless sensor networks where the sensors are energy-constrained. Our protocol is aiming at maximizing the duration before the network becomes inoperative due to the lack of battery energy at sensors. An appropriate selection of transmitting sensors,...[Show more]
