Provided are a simulation apparatus and method used to simulate a sensor network. A sensor node of a real node is reflected in a simulation, and bidirectional communication is performed between a real node and a virtual node, in order to reflect a real environment and a simulation environment in each other and make the real node and the virtual node consistent with each other, thereby performing simulation.

Simulation apparatus and method used for sensor network

A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.
