EXTENSIBLE VIRTUAL MACHINE FOR REPROGRAMMING IN WIRELESS SENSOR NETWORKS AND REPROGRAMMING METHOD USING IT |
摘要 |
<p>An extensible virtual machine for changing a program in a wireless sensor network environment and a reprogramming method using the same are provided to enable a program made of native codes to be executed by adding a download manager module and a symbol table to a virtual machine within a sensor node, thereby making change and execution of the program with low power by reducing the overhead of an existing virtual machine. An extensible virtual machine(101) for changing a program in a wireless sensor network environment comprises the followings: a symbol table(103) which stores the program memory address of an updated dynamic memory; and a download manager module(102) which downloads a new dynamic memory through a network, load the new dynamic memory to a program memory, and updates the address of the program memory, where the dynamic module is stored, in the symbol table.</p> |
