“…This feature makes DASH7 is a good candidate for wireless sensor network (WSN) applications. In a DASH structured WSN, there can be four different device classes defines, namely; Blinker, Endpoint, Sub-controller and Gateway [14]. The detailed specifications of these devices are given in Table II.…”

Considering the inability of the existing energy resources to satisfy the current needs, the right and efficient use of the energy has become compulsory. To make energy sustainability permanent, management and planning activities should be carried out by arranging the working hours and decreasing the energy wasting. For all these, power metering, managing and controlling systems or plugs has been proposed in recent efforts. Starting from this point, a new DASH7-based Smart Plug (D7SP) is designed and implemented to achieve a better structure compared to ZigBee equipped models and reduce the drawbacks of current applications. DASH7 technology reaches nearly 6 times farther distances in comparison with 2.4 GHz based protocols and provides multi-year battery life as a result of using limited energy during transmission. Performing in the 433 MHz band prevents the possible interference from overcrowded 2.4 GHz and the other frequencies which helps to gather a more reliable working environment. To shorten the single connection delays and human oriented failures, the MCU was shifted directly into the plug from the rear-end device. Working hours arrangement and standby power cutting off algorithms are implemented in addition to these energy saving targeted improvements to enhance more efficient systems. With the collaboration of the conducted hardware and software oriented healings and DASH7-based improvements, a more reliable, mobile and efficient system has been obtained in this work.

“…DASH7 is usually preferred over ZigBee (The ZigBee Alliance, 2015) due to its larger range (Weyn et al, 2013;Chehri et al, 2012; Dash7 mode2, 2015) and penetration capability which makes it a better choice for harsh environment such as underground mines. Gaussian frequency shift keying (GFSK) is used as a modulation technique with a modulation index of 0.5 and a baud rate of 200 KBaud/sec, whereas PN9 encoding has been used in this standard.…”

Detection and self-healing of cluster breakages in mines and tunnels: an empirical investigation

et al. 2015

Purpose -The study aims at providing a reliable system of real-time monitoring for underground mine and tunnels which detects any structural change in the network and reconfigures it for resuming the data delivery process. In high stress environments, e.g. underground mines and tunnels, real-time activity monitoring is an emerging issue. Wireless sensor networks (WSNs) play a key role in ensuring the safety of people working in underground mines and tunnels. WSN not only provide real-time monitoring of underground environment but also detects any structural change in the network itself. Design/methodology/approach -In this paper, results of empirical implementation of a re-configurable WSN, capable of self-healing approach, reconfigure the network connectivity upon failure or addition of nodes in the system. An open-source radio-frequency identification standard for WSN, named as DASH7, is used for practical implementation. The proposed system is capable of determining cluster breakage by sudden disruptions caused by roof falls, explosions and node failures, sensor coverage hole, node re-addition to the network and distress priority signal generation by the miner. Findings -The proposed platform contributes to re-attain network state for establishing a communication link with fusion center in terms of: instant and accurate detection of collapse holes, acceptable error rate, time to re-attain network state, rapid distress signal propagation and low deployment cost. This platform is deployed in four different environments of anechoic chamber, hallway, outdoor and underground mine environment, to test the aforementioned scenarios using DASH7-compatible Bitsense Sensor Motes operating at 433 MHz. The effectiveness of the proposed approach has been experimentally validated for the single and multiple adjacent and disjoint node failures in all the four environments. Originality/value -The number of monitoring systems was implemented for safety assurance in high stress environments before, but the novelty of our platform is long range, cost effectiveness, quick response to any structural change in the network, rapid and accurate data delivery using WSN operated on DASH7 protocol stack.

Our aim in this paper is to use the freely available OSS-7 implementation stack of DASH7 RFID based WSN protocol and improve its existing software scheduler for better energy consumption. We have proposed substantial changes in the scheduler for OSS-7 v1.0 in terms of insertion, sorting and search algorithms. This scheduler fulfils the functionality and at the same time it is extremely light weight to cater to the memory constraints on the target Texas Instruments Wizzimote platform. This gives us performance improvements up to 75%, on average, in terms of execution time thus leading to reduced dynamic power consumption.
