Abstract

A network protocol for low-cost, low-power device 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 (991) in conjunction with the maintenance phase (905) insures the self-organizing capability of the network. At the same time, the maintenance (905) operations provide a self-healing mechanism (920) 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.

Description

[0001] This application is related to applications titled "System for Spread Spectrum Communication (Docket No. CM03351J)", "A Multiple Access Protocol and Structure for Communication Devices in an Asynchronous Network (Docket No. 3526J)" and "System for CodeDivision Multi-Access Communication (Docket No. 03333J)" application. technical field [0002] The present invention relates to wireless communication networks, and more particularly, to the application of network protocols in wireless communication networks. Background technique [0003] Wireless communication networks typically include a large number of devices that may be distributed randomly in indoor and / or outdoor communication environments. The important issue is how to organize these communicating devices physically and logically, so that efficient inter-device communication can be achieved, and the resulting network is robust, scalable, and able to adapt to changes in the network layout. The primary wireless ne...
