—Many recent advances in MAC protocols for wireless sensor networks have been proposed to reduce idle listening, an energy wasteful state of the radio. Low-Power-Listening (LPL) protocols transmit packets for ti s (the " inter-listening interval "), thereby allowing nodes to sleep for long periods of time between channel probes. The inter-listening interval(More)
—Energy efficiency is of the utmost importance in wireless sensor networks. The family of Low-Power-Listening MAC protocols was proposed to reduce one form of energy dissipation—idle listening, a radio state for which the energy consumption cannot be neglected. Low-Power-Listening MAC protocols are characterized by a duty cycle: a node probes the channel(More)
Protocols for wireless sensor networks (WSNs) are very diverse. Reflecting this diversity, no single protocol architecture for WSNs dominates: programmers often modify the legacy-architecture to fit their set of protocols in the stack. However, there exists desirable goals for a sensor network architecture: modularity, flexibility and universality. At the(More)
Low-power-listening MAC protocols were designed to reduce idle listening, a major source of energy consumption in energy starved wireless sensor networks. Low-power-listening is a MAC strategy that allows nodes to sleep for t i s (the " inter-listening " time) when there is no activity concerning them. It follows that a node has to occupy the medium for at(More)
As wireless sensor networks gain in popularity, many deployments are posing new challenges due to their diverse topologies and resource constraints. Previous work has shown the advantage of adapting protocols based on current network conditions (e.g., link status, neighbor status), in order to provide the best service in data transport. Protocols can(More)
