摘要: The invention concerns a method for channel allocation in an ad-hoc radio communication system comprising devices gathered several piconets. A piconet coordinator (PNC) is defined each piconet. Code Division Multiple Access (CDMA) scheme implemented. set of available codes split into pre-defined disjoined subsets (Ci) known by device. In subset (Ci), one code denoted Ci be) used broadcast. For new device added the system, includes following steps: scans its environment looking at least (Ck) which associated to piconet, depending on or found (Ck): becomes (PNC), joins existing among
