In addition to fixed sensor network such as crop cultivation management system, studies on mobile sensor network have been actively conducting, which is used for collecting information from the moving objects like livestock and cars with use of sensors.The mobility of node enables to prolong the lifespan of network and to manage network efficiently through equal allocation of energy among nodes.To ensure efficient mobility, it is required to make a functional change to MAC layer and routing protocol.In particular, an enhanced transmission mechanism is essential in order to effectively control a link discontinuity or an increase of traffic overhead caused by the mobility of node.This paper aims to propose an energy-efficient transmission mechanism using distance information between sensors in mobile sensor network.Performance of the proposed mechanism has been evaluated by simulation.The simulation results indicate that the proposed mechanism outperforms traditional minimum hop routing method from the perspective of several performance indicators including average packet latency, average energy consumption and network lifespan.
