Description
Technical field
The present invention relates to field of communication technology, the one kind further related in wireless communication field is based on pure directional aerial
Neighbors rapid discovery method.This method realizes that the quick discovery and conflict of neighbors in wireless, autonomous communications network are kept away
Exempt from, pure one important component of directional antenna communications agreement can be used as.
Background technology
Using directional aerial into the common omnidirectional antenna of row information transfer ratio have transmission range it is farther, speed higher, safety
Property higher and realize the advantage of spatial reuse.At present, the mode transmitted using directional aerial into row information is roughly divided into two kinds：Band
The pure directional transmissions of the directional transmissions and directional reception directive sending of omnidirectional antenna or channel auxiliary.With omnidirectional antenna or channel
The directional transmissions of auxiliary can simply and efficiently realize that neighbors finds information transmission, but the construction complexity of antenna equipment is unfavorable
Carried in mobile；Pure directional transmissions mode antenna structure is simple, however, it was found that mechanism and transport protocol design are relative complex.
Zhensheng Zhang are in paper " Pure Directional Transmission and Reception
Algorithms in Wireless AdHoc Networks with Directional Antennas”(Published
in:Communications,2005.ICC 2005.2005IEEE international Conference on,0-7803-
A kind of neighbors that information is received and transmitted using directional aerial is proposed in 8938-7) and finds method.This method pair
The ID number of antenna node carries out binary system evaluation, will further according to the length of the maximum node number polishing binary sequence in network
The binary sequence carries out neighbors scanning as antenna scanning mode sequences, and three steps are carried out in the sector of a directional aerial
Shake hands interaction, complete pure orientation neighbors and find, but shortcoming is existing for this method, the interaction of shaking hands of three steps is orienting
Completed in one sector of antenna, more demanding to antenna configuration, the slow-footed directional aerial of pattern switching does not apply to simultaneously, does not have
The chance that part of nodes is received or sent within the scan period can be made by distributing more reasonably scanning sequence, its scanning sequence to node
Very little, and without the method for solving signal conflict, larger transmission delay can be produced when the number of nodes in network is more.
The patent that No.54 Institute of China Electronics Science ＆ Technology Group applies at it is " a kind of based on the new of directional aerial
Type neighbor discovering method " (number of patent application：CN201310695670.5, publication number：CN103686611A one kind is proposed in)
The pure orientation neighbors for adding random silencing mechanisms finds method.This method is added on the basis of using Binary Scanning sequence
Random silencing mechanisms achieve the purpose that to avoid signal conflict, and silent status is the state for neither sending nor receiving, antenna section
Initial time of the point in the scan period generates a random number, and the random number is compared with corresponding threshold value, if this is random
Number is put into silent status less than threshold value, otherwise can be to avoid part signal conflict into scanning mode, this method.But should
The shortcoming that method still has is that signal conflict is not judged, it is impossible to avoids signal conflict, and meeting exactly
The antenna node for making not conflict enters silent status and causes to find whole neighbors.
