Health Monitoring of Civil Infrastructures Using Wireless Sensor Networks Sukun Kim Shamim Pakzad David E. Culler James Demmel Gregory Fenves Steve Glaser Martin Turon Electrical Engineering and Computer Sciences University of. This wireless sensor networks is depends on a simple equation. To support the sustainable operation of wireless sensor networks using limited energy, duty cycling is a promising solution. However, it is a challenge to guarantee each node communicating with its neighbors under duty cycle. On Multihop Broadcast over Adaptively Duty-Cycled Wireless Sensor Networks. We consider the problem of multihop broadcast over adaptively duty-cycled wireless sensor. He, T.: Opportunistic flooding in low-duty-cycle wireless sensor networks with. A reliable broadcast service for large. Duty-Cycle-Aware Broadcast in Wireless Sensor Networks. Energy- efficient reliable data dissemination in duty- cycled wireless sensor networks. Abstract. Because data dissemination is crucial to Wireless Sensor Networks (WSNs), its energy- efficiency and reliability are of paramount importance. While achieving these two goals together is highly non- trivial, the situation is exacerbated if WSN nodes are duty- cycled (DC) and their transmission power is adjustable. In this paper, we study the problem of minimizing the expected total transmission power for reliable data dissemination (multicast/broadcast) in DC- WSNs. Due to the NP- hardness of the problem, we design efficient approximation algorithms with provable performance bounds for it. DOI: 1. 0. 1. 14. Extracted Key Phrases.
