A Routing Algorithm Based on Mobile Agent for Mine Monitoring

The monitoring system in coal mine has special requirements for data query. Analysis shows that routing in the system should have four features: data-centric routing, supporting query of geographic position, low delay and high reliability of data transmission, robustness of topology. A mobile agent based routing algorithm with mobile sink and a dynamical weight metric which is derived from its current position and some QoS parameters is presented to meet the above-mentioned features. The mobile agents can determine their own routes and apply mobile sinks when topology changes. Simulation results show that the route algorithm can reduce high delay and low reliability of the monitoring system in coal mine.
