COMMUNICATION METHOD FOR MESH AND STAR TOPOLOGY STRUCTURE WIRELESS SENSOR NETWORK

摘要

A connnunication method for a mesh and star topo1 ogy structure wireless sensor network (MSTN) includes these steps: various nodes in a wireless sensor network are arranged in a mixed mesh and star topology structure; an IEEE 802.15.4 based superframe structure is defined on the basis of the topology; a 1ong-period data processing method, a connectivity measurement method, a medium access control method, a channel measurement method, a frequency hopping method, a beacon frame format and a two-phase communication resource distribution method are defined on the basis of the topology and superframe structure; a network construction method are defined on the basis of the topology structure, the superframe structure and the methods; a communication method which can implement the MSTN communication process is constructed on the basis of the network constmction method.
