The Research Of Hotspot Clustering Algorithm

Ad Hoc network is self-created, self-organized, and self-administered. At home and abroad, there is wide range of researches on Ad Hoc. The research of Ad Hoc has developed into a brand new field from a branch of tele-communication. The literature of Ad Hoc network research is carefully scrutinized in this paper. It's obvious that Ad Hoc network is a complex system, due to its own characteristics like dynamic topology, power limits, physical security, etc. In Ad Hoc network, a node must interact with other nodes in the web during transmission; The routing information collected during transmission changes constantly; Moreover, due to the motion of the nodes in the network, action like transmission, routing information collection is self-decided, so there is the emergency characteristic of complex system. The pros and cons of traditional researches on network route planning are analyzed. From the angle of Complex Adaptive System theorem, we combine trade-offs referred to in Clustering algorithm, the rational localization and multi-agents theorems to do some research on hotspot phenomena in Ad Hoc network, and obtain good results. In order to solve the hotspot phenomena of Ad Hoc, without exerting control on the motions of the nodes, we construct the clusters around hotspot nodes by introducing info flows as a new parameter. Through establishing local rules to approximate the global goals, we try to use control theorem in Ad Hoc network research. The application of control theorem to the telecommunication is pushed further.
