Abstract
A network node is configured control operations in a wireless computer network and to automatically hand over network master operations to an alternate network master device upon detecting an operational failure of the network node. In a further embodiment, in response to detecting at a network node of a wireless computer network an impending operational failure of the network node, the node automatically negotiates the hand over of network control responsibilities for the wireless computer network to an alternate network master. Such network control responsibilities may include bandwidth allocation among network clients within the wireless computer network. In still another embodiment, in response to detecting at a node of a wireless computer network (e.g., utilizing a half-duplex communication link) the absence of a master network node, the node will automatically configure itself as an alternate network master. This process may include negotiating with other master-capable nodes of the network for control of the network. Further, the node may search for an absent master node before assuming control of the network.
