Fisheye State Routing (FSR) is an implicit hierarchical routing protocol. Also considered a proactive protocol and is a link state based routing protocol that has been adapted to the wireless ad hoc environment. Relays on link state protocol as a base, and it has the ability to provide route information instantly by maintaining a topology map at each node. Thus will maintain updated information from the neighbor node through a link state table. In each node the network, a full topology map is stored then utilized (List of ad hoc routing protocols). According to Kleinrock and Stevens, FSR uses the "fisheye" technique where the technique was used to reduce the size of information required to represent graphical data. The eye of a fish captures with high detail the pixels near the focal point. The detail decreases as the distance from the focal point increases. In routing, the fisheye approach translates to maintaining accurate distance and path quality information about the immediate neighborhood of a node, with progressively less detail as the distance increases. == Algorithm == FSR is based on a link-state foundation updating mechanism. Which has the following feature: maintaining a topology map at each node. this mechanism reduces the control overhead by disseminating topology information using the fisheye technique, where routing information is updated at different rates depending on the distance from the source.and it can be broken down into : • 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fisheye State Routing」の詳細全文を読む スポンサード リンク
