Dynamic network master handover scheme for wireless computer networks
First Claim
1. A method comprising:
- transmitting one or more connection requests from a first node on a network to one or more other nodes on the network;
receiving no response from an original network master device;
causing the first node to enter a master search negotiation mode, wherein the first node communicates with the one or more other nodes on the network to determine which device will attempt to locate the network master device;
designating the first node or other node as a master search device, wherein the designated master search device searches for the silent original network master device by transmitting one or more connection requests at various intervals over one or more available communications channels; and
reverting the node acting as the master search device to normal network operations if a response is received from the original network master device.

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.

3. The method of claim 2, further comprising:
causing the substitute network master device to enter a master handover mode upon said detection of operation of the original network master device.
-
4. The method of claim 3, further comprising:
-
receiving a command from the original network master device instructing the substitute network master device to cease network master operations;
automatically transferring control of network operations from the node acting as the substitute network master client to the original master device upon receipt of said command; and
causing said node to resume operations as a network client upon successful handover of control to the original network master device.
