Method of fragmenting a message in a network
First Claim

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 size is at least 4 bytes smaller than the available space and the at least 4 bytes corresponds to 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 of the at least one numbered fragmented message into the first packet; and
sending the first packet over the network.

Abstract
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.

12. 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 size is smaller than the available space; 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 of the at least one numbered fragmented message into the first packet; sending the first packet over the network; and determining a number of nodes over the network, wherein determining a fragmented message size for fragmenting the message includes determining the fragmented message size so that the fragmented message size is smaller than the available space by a number of bytes with respect to the number of nodes.

13. 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 size is smaller by a number of bytes than the available space and the number of bytes corresponds to 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 of the at least one numbered fragmented message into the first packet; sending the first packet over the network; receiving the first packet sent over the network; performing source routing in the network with respect to the received packet; updating the network header of the first packet to obtain a later packet; and sending the later packet over the network, wherein the first packet includes a free space, and at least a portion of the free space is occupied in the later packet.
