| With the development of the sensor network, the warfare has been changed from the three-dimensional warfare of land, sea, sky to the multidimensional network central war of land, sea, sky, spaceflight and electromagnetism. The network central war gained sharing apperceive, increase the speed of commanding, quicken cadence of the war, aggrandize the execution, boost up the survival ability, improve the ability of synchronization, to form new battle effectiveness.The sensor network is an important part of the network central war. It radically changes the mode of the sensors changing and dealing with the information in the cell of battle. The sensor network can exert the validity of the radar and other sensors to the best. It can offer the "battlefield situation map".The sensor network system has many kinds of heterogeneity. The platform of hardware, the operating system,database all have heterogeneity. The virtual machine (VM) technology shields the heterogeneity of the sensor network. It is needed to generate the objective code in the virtual machine to run in many kinds of the platform that is not necessary to modify. The VM technology decreased the complications of the cross-platform software development, shorten the development time, reduced the development cost. It has the inborn advantage in development of the sensor network.This paper is based on the VM technology and the research of the sensor network. It advances a kind of solving scheme and simple emulator to share the heterogeneous resources in the sensor network. This method is based on the VM. For the speed of the JVM is slowly. The Generational Garbage Collector and the mechanism of loading classes are ameliorated. |
