TLDR
This paper evaluates the ideas already presented, specifically the EnviroMic, for data collection and storage and applies a realistic power consumption model to estimate the lifetime of an audio sensor network.Abstract:
Wireless sensor networks (WSNs) can be used to record and store audio data at remote and inaccessible places. However, audio data adds an additional concern to the design of the WSN; the motes need a larger amount of memory resources to be able to store the collected data. In this paper, we evaluate the ideas already presented, specifically the EnviroMic, for data collection and storage and apply a realistic power consumption model to estimate the lifetime of an audio sensor network.read more

Energy-efficient collision-free medium access control for wireless sensor networks
TL;DR: The traffic-adaptive medium access protocol (TRAMA) is introduced for energy-efficient collision-free channel access in wireless sensor networks and is shown to be fair and correct, in that no idle node is an intended receiver and no receiver suffers collisions.

The coverage problem in a wireless sensor network
Chi-Fu Huang,Yu-Chee Tseng +1 more
TL;DR: This paper presents polynomial-time algorithms, in terms of the number of sensors, that can be easily translated to distributed protocols, and forms a decision problem to determine whether every point in the service area of the sensor network is covered by at least k sensors.

Impact of radio irregularity on wireless sensor networks
TL;DR: The RIM model is the first to bridge the discrepancy between spherical radio models used by simulators and the physical reality of radio signals, and shows that radio irregularity has a significant impact on routing protocols, but a relatively small impact on MAC protocols.

The coverage problem in a wireless sensor network
Chi-Fu Huang,Yu-Chee Tseng +1 more
TL;DR: This paper forms the coverage problem as a decision problem, whose goal is to determine whether every point in the service area of the sensor network is covered by at least k sensors, where k is a given parameter.
