Method of fragmenting a message in a network

摘要

Embodiments described herein provide a method of fragmenting a large message into, for example, numbered packets for sending the message in a packet based communication system, such as in a ZigBee wireless network. Each packet may have a predetermined size and may include a MAC address, a network header of a variable size, and fragmented message data. The fragmented message data can be configured to be smaller than the available space in the packet so that the packet can be sent, for example, when the size of the header increases.

1. A method of sending a message in a packet-based network, comprising:
determining an available space in a first packet; determining a fragmented message size for fragmenting the message, wherein the fragmented message is at least 4 bytes smaller than the available space and the at least 4 bytes corresponds to two additional nodes in the packet-based network; fragmenting the message into at least one numbered fragmented message, each of the at least one numbered fragmented message has the fragmented message size; assembling a first fragmented message into the first packet; and sending the first packet over the network.
