“…Specifically, the higher transmission reliability associated with less packet loss is crucial for almost all types of underground sensing applications [1]. Also, the bounded delay is especially important for real-time monitoring and applications with timing constraints [30]. Aiming to support the distributed functionalities among sensors, we form the per-node based constraints (i.e., for transmissions upon link i − j) of link reliability and delay in the following.…”

Wireless underground sensor networks (WUSNs) enable many applications such as underground pipeline monitoring, power grid maintenance, mine disaster prevention, and oil upstream monitoring among many others. While the classical electromagnetic waves do not work well in WUSNs, the magnetic induction (MI) propagation technique provides constant channel conditions via small size of antenna coils in the underground environments. In this paper, instead of adopting currently layered protocols approach, a distributed cross-layer protocol design is proposed for MI-based WUSNs. First, a detailed overview is given for different communication functionalities from physical to network layers as well as the QoS requirements of applications. Utilizing the interactions of different layer functionalities, a distributed environment-aware protocol, called DEAP, is then developed to satisfy statistical QoS guarantees and achieve both optimal energy savings and throughput gain concurrently. Simulations confirm that the proposed cross-layer protocol achieves significant energy savings, high throughput efficiency and dependable MI communication for WUSNs.Index Terms-Wireless underground sensor network, magnetic induction communication, cross-layer optimization, Pareto optimal front, distributed power control, distributed protocol.

“…Recently, Bedford and Kennedy [7] have analyzed the applicability of ZigBee (IEEE 802.15.4) devices for time-of-flight (TOF) measurements. It should be noted that numerous other radio frequency (RF)-based local positioning systems [8]- [11] are currently available on the market which are also using TOF measurements and promise centimeter-level accuracy.…”

The surroundings of underground mining machines still constitute an unsafe area for miners due to bad visibility conditions. In this paper, we present a novel acoustic position estimation system for safety applications in such hazardous environments. Our system is based on a pulse compression technique and utilizes linear (LFM) and hyperbolic (HFM) frequency-modulated signals in the frequency range of 5-20 kHz. As the miners are moving, we incorporated a means of Dopplershift compensation. This system not only provides the positions of moving targets but also their velocity and direction. In stationary measurements, we evaluated LFM signals at noisy conditions both in an indoor laboratory environment and in the vicinity of a mining machine. The movement of a miner has been emulated in dynamic laboratory measurements at constant speeds up to 1 m/s using both LFM and HFM signals. Our results show that the acoustic signal can be evaluated down to a low signal-to-noise ratio of −30 dB. The results of the dynamic measurements clearly demonstrate the insensitivity of the HFM signals to Doppler-shifts both with regard to the estimated position and estimated velocity.

“…These, however, result in larger antennas being deployed underground, which is theoretically desirable but less practical because of the limited space in existing manhole chambers, etc. For these reasons, it is preferable, if challenging, to use established mobile-band frequencies for wireless sensor to sensor (STS) communications underground, and sensor to base station (STB) communication from underground to above ground [13], [14].…”

A subsurface chamber transceiver system and associated propagation channel link budget considerations for an underground wireless sensor system (UWSS) are presented: the application was a sewerage system for a water utility company. The UWSS operates over the GSM850/900, GSM1800/1900, and Universal Mobile Telecommunications System (UMTS) bands in order to operate with the standard public mobile phone system. A novel antenna was developed to minimize path loss from the underground location: a folded loop type, which is small enough to fit conveniently inside a utility manhole access chamber while giving adequate signal strength to link to mobile base stations from such a challenging environment. The electromagnetic performance was simulated and measured in both free space and in a real manhole chamber. An experimental test bed was created to determine the return loss and received signal strength with different transceiver positions below the manhole chamber access cover. Both numerical and experimental results suggested an optimum position of the unit inside the manhole, combining easy access for maintenance with viable received signal strength. This confirmed that the characteristics were adequate for incorporation in a transceiver designed to communicate with mobile base stations from underground. A field trial confirmed the successful operation of the system under severe conditions.
