A method for multicast communication in a network having plural nodes according to the ZigBee network specification includes creating a multicast group including a subset of the plural nodes and excluding at least one non-member node in the plural nodes. The multicast group has a multicast address. The method also includes transmitting multicast message including the multicast address and receiving the multicast message at each node in the multicast group.

Method, apparatus and system for multicast communication in a wireless multi-hop network

A method assigns addresses to nodes in a wireless network. An address space is defined as an n-dimensional grid. Each grid intersection has coordinates of a corresponding possible node of a wireless network. A number of components of each coordinate is equal to a dimensionality of the grid, and the coordinates form a logical address of the corresponding node. A parent node assigns an unallocated logical address as a child node address to a child node joining the wireless network such that one component of the child node address is one larger than a corresponding component of the parent node.
