Motivated by stringent power constraints, duty cycling-the practice of turning a mote's radio
on and off to conserve energy-has become a fundamental mechanism in the design of …

Wireless sensor networks (WSNs) are resource-constrained networks with limited battery
power, computation abilities and communication capabilities at the sensor node level. A …

In the last years, wireless sensor networks (WSNs) have gained increasing attention from
both the research community and actual users. As sensor nodes are generally battery …

Routing in battery-operated wireless networks is challenging, posing a tradeoff between
energy and latency. Previous work has shown that opportunistic routing can achieve low …

Low duty cycle operation is critical to conserve energy in wireless sensor networks.
Traditional wake-up scheduling approaches either require periodic synchronization …

In recent years, the use of wireless sensor networks for industrial applications has rapidly
increased. However, energy consumption still remains one of the main limitations of this …

Opportunistic routing is widely known to have substantially better performance than unicast
routing in wireless networks with lossy links. However, wireless sensor networks are usually …

Neighbor discovery was initially conceived as a means to deal with energy issues at
