摘要： Provided is a multi-route routing scheme that supports Quality of Service (QoS) in the wireless mesh network. A method of notifying about and avoiding congestion situation in data transmission in a wireless mesh network and a mesh node may also be provided. Data may be differentially transmitted to multiple routes by obtaining a route congestion level existing in a current multi-hop route and thus, data providing a real-time service, such as a video streaming service, may avoid congested routes and may be promptly transmitted. Multiple queues in a mesh node may be divided into divided queues based on a congestion situation of a transmission route in a network and the divided queues may be transmitted through multiple routes and thus, an efficiency of the overall network may increase.

摘要： 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.

摘要： In the present invention a mask (21) with a concentric pattern (a,b,c,d) is fabricated and aligned on a substrate (130) coated with a photoresist (131) and is then light-exposed. The light-exposed substrate is developed to obtain a concentric pattern of the photoresist in the form of tori. Then, a reflow process is performed for the developed substrate to allow the photoresist in the form of tori to be curved. A stamper in which the concentric pattern of the photoresist in thr form of tori is engraved in a depressed fashion is fabricated. Thereafter, by using the stamper as a mold, a lens and a lens array with the concentric pattern are formed.
