摘要： A method and apparatus for providing quality of service over a contention access period of a wireless personal area network is provided herein. Particularly, the layers above the MAC are allowed to reserve portions of a contention access period (CAP) in order to schedule their QoS actions cooperatively thereby avoiding the dependence on the MAC for QoS performance. By using cooperative scheduling, a node can send a QoS packet from the QoS_Layer to the MAC, and know that it will be transmitted according to the specified QoS requirement. As a result, whenever a node sends a QoS packet in the reserved portion of the CAP, the channel will be guaranteed to be free from competing nodes' packets because those competing nodes will delay their transmissions based on the shared schedule.

摘要： In order to discover neighboring nodes (203, 207, 208) within a particular piconet, a first node (206) determines a list of all nodes (205-207) within its piconet (201) and then transmits to each node within the piconet, a message requiring a response. Depending upon which nodes are heard from, a list is formulated by the first node comprising those nodes neighboring the first node. In order for neighboring nodes within other piconets to “discover” the first node, the first node will also scan its environment to determine piconet identifications for other piconets, and then broadcast a “discovery” message having a piconet identification of a neighboring piconet. In a similar manner, the first node will also scan its environment to determine discovery messages transmitted by other nodes, thus determining neighboring nodes outside its piconet.

摘要： A communication device (111) determines whether to operate as a cluster head in a network of communication devices (100). The device performs a self-assessment regarding its ability to operate as a cluster head based on a formula that assigns weights to factors related to its capabilities and preferably its environment (410, 420, 430). The ability of the device is combined with a random value component in determining whether to operate as a cluster head (440). In the preferred embodiment, upon assumption of cluster head status, the device communicates with neighboring devices to signal its cluster head status, and to invite others to participate in the formation of a cluster.

摘要： A network protocol for low-cost, low-power devices coupled to a self-organizing wireless network using a spanning tree backbone architecture is described. In this protocol, physical and logical network construction and maintenance operations, which supports efficient data routing in the network, are performed. The construction phase in conjunction with the maintenance phase insures the self-organizing capability of the network. At the same time, the maintenance operations provide a self-healing mechanism so that the network can recover from node failures and a self-updating mechanism so that the network can expand as more nodes enter the system. Also, the logical backbone hierarchy will facilitate multi-hop communication. The construction of a logical layered spanning tree backbone architecture from an underlying physical topology allows seamless data communication routing between all nodes in the network.
