sDEVELOPMENT OF COAL MINE SAFETY SYSTEM USING WIRELESS SENSOR NETWORKS
In this work, a system is proposed for safe Coal Mine Monitoring, which plays an important role in coal mine safe production. Wi th continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, wh ere are lots of hidden dangers. It is very difficult to lay cables which are not reliable and not effective. For to overcome this , a new s...
متن کاملCongestion Control Approaches Applied to Wireless Sensor Networks: A Survey
Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...
متن کاملAnchor-Free Localization Method for Mobile Targets in Coal Mine Wireless Sensor Networks
Severe natural conditions and complex terrain make it difficult to apply precise localization in underground mines. In this paper, an anchor-free localization method for mobile targets is proposed based on non-metric multi-dimensional scaling (Multi-dimensional Scaling: MDS) and rank sequence. Firstly, a coal mine wireless sensor network is constructed in underground mines based on the ZigBee t...
متن کاملDesign of an Adaptive Coal Mine Rescue Robot using Wireless Sensor Networks
In early decades, rescue operation in coal mine was treated as a dangerous task. After explosions occur, when rescue workers get into the tunnel without environment conditional awareness, they are facing heavy damages due to consecutive explosions [1]. This bring the necessity to detect the status of the mine environment details such as toxic gases, high temperatures through wireless sensors to...
متن کاملApplied Formal Methods in Wireless Sensor Networks
When considering the use of formal methods, a still prevailing view is its application of mathematical models and techniques for the analysis of information and communication technologies. Model checking is a branch of this, offering an exhaustive investigation method of the model spanned search space via brute-force algorithms. Hereby the analysis is not only restricted to qualitative statemen...
