In wireless sensor networks with mobile sinks, it is a challenge to design reasonable data dissemination protocols to realize reliable, real-time and efficient data transmission from multiple sources to multiple sinks. Recently, many protocols such as TTDD, GHT and LBDD are proposed to solve this problem. However, most of them depend on the whole network topology information to optimize the data dissemination...
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...
