Energy Optimized Routing Algorithm for Hybrid Wireless Mesh Networks in Coal Mine

Abstract

Mesh clients in hybrid wireless mesh networks can participate in networking and routing. When the backbone transmission network is broken, the mesh client can route and forward the data, which will eliminate the absolute dependence on the backbone network of traditional infrastructure wireless mesh networks in mine emergency rescue. However, the energy of mesh clients is limited. Based on the comprehensive consideration of the efficiency and balance of energy consumption of mesh clients for data transmission, a new energy cost criterion is designed. Energy optimized and fault recovered routing algorithm is proposed on account of different network states. At last, the simulation analysis on the performance of routing algorithm is conducted and compared with typical routing algorithms. Simulation results show that the algorithm has effectively extended the network lifetime and achieved optimized combination of energy efficiency and energy balance. When mesh routers in the backbone network are failed, this algorithm can rapidly rebuild the route and shows strong capacity of routing recovery.

Fuzzy-logic-based data-differentiated service supported routing protocol for emergency communication networks in underground mines

“…Coal consumption accounts for 70% of the non-renewable energy consumption at the present stage. 7 In recent years, the safety of coal mining has been paid more attention with the increase in depth and intensity in production processes. The terrain of an underground mine is complex, and the environment of mining production is terrible.…”

Regional energy- and mobility-aware routing protocol for hybrid wireless mesh network

“…No-balance degree of remaining energy in mesh clients: the standard deviation of remaining energy of all mesh clients in the whole network when the first mesh client becomes invalid due to the exhausted energy. 27,28 Network lifetime: the run time until the first client runs out of energy. The unit is seconds.…”

A Routing Protocol for Multisink Wireless Sensor Networks in Underground Coalmine Tunnels

“…The first-order radio energy consumption model proposed in [35,36,37,38,39] is used in our study; the model considers both the transmitting energy and receiving energy consumption. Based on this model, the energy consumed by the data transmission of lbit to s is shown as follows, $E_{Tx}\left(l,s\right)=\{\begin{array}{c}leftl{E}_{elec}+l{\epsilon }_{fs}{s}^2,s<s_0\\ l{E}_{elec}+l{\epsilon }_{mp}{s}^4,s\ge s_0\end{array},$ where E elec refers to the energy consumed by the transmitting circuit.…”
