APPARATUS AND METHOD FOR COMMUNICATION IN WIRELESS SENSOR NETWORK

摘要

A communication apparatus in a wireless sensor network and a method thereof are provided to prevent mutual interference between clusters, thereby easily constructing a cluster tree. A node is scanned(S505). If an NOAD(the Number Of Associated Device) of a beacon received from a PNC does not exceed the maximum value, a channel and window selection algorithm is performed(S520). A parent node is determined(S540). The node joins as a device(S550). If a connectable coordinator is not found, the node becomes an orphan(S510,S530,S590).
