The HiperLAN Type 2 (H/2) standard developed by the European Telecommunication Standards Institute (ETSI) supports two profiles, Home Environment Extension (HEE) and Business Extension. With the HEE profile a 'one hop'-ad hoc network configuration, a so called single subnet, is provided. All devices participating in such an H/2 subnet operate on the same frequency channel whereby the channel access is coordinated by a Central Controller (CC) that is an H/2 terminal itself. All H/2 home devices (CC-capable) are able to perform the CC specific functions in addition to general terminal functions. During the network establishment phase or whenever an active CC is lost, a new CC must be selected among all CC-capable terminals forming the subnet. In general, each terminal first tries to join an existing wireless network by scanning frequencies for an active CC. If no association to any CC is possible, the CC Selection is started. This collision resolution mechanism is performed in a decentralized way by every terminal. It consists of alternating probing and frequency scanning phases. Based on the result of the CC Selection algorithm each CC-capable device decides on its own whether to become a wireless terminal (WT) or to take over the CC functionality. This paper presents the CC Selection concept, a performance analysis, the validation of system parameters and a comparison to the master election in Bluetooth Piconets.
