Method for communicating in a network comprising a batteryless zigbee device, network and device therefor
First Claim
1. A system for wireless communication in a network, the system comprising:
- a resource-restricted device configured to transmit a data frame to be forwarded to a destination device in the network, wherein the data frame includes a source identifier of the resource-restricted device, wherein the source identifier is not a valid network address for the network;
a proxy device configured to receive the data frame from the resource-restricted device;
the proxy device configured to derive a network address for the resource-restricted device as a function of the source identifier of the resource-restricted device;
the proxy device configured to construct, from the data frame, a packet to be forwarded to at least the destination device, wherein the packet, comprises data from the data frame, and the derived network address for the resource-restricted device as a source address for the packet; and
the proxy device configured to associate a delay to the packet, and schedule transmission of the packet after the delay.

Abstract
A system for wireless communication in a network includes: a resource-restricted device transmitting a data frame to be forwarded to a destination device in the network, wherein the data frame includes a source identifier of the resource-restricted device, wherein the source identifier is not a valid network address for the network; a proxy device receiving the data frame from the resource-restricted device, deriving a network address for the resource-restricted device as a function of the source identifier of the resource-restricted device, and constructing, from the data frame, a packet to be forwarded to at least the destination device. Constructing the packet involves: including, in the packet, data from the data frame, and including, in the packet, the derived network address for the resource-restricted device as a source address for the packet. The proxy device associates a delay to the packet, and schedules transmission of the packet after the delay.

15. A proxy device, comprising:
-
reception means for receiving a data frame from a resource-restricted device in a wireless network, wherein the data frame includes data and a source identifier of the resource-restricted device, wherein the source identifier is not a valid network address for the network; first determination means for deriving a network address for the resource-restricted device as a function of the source identifier of the resource-restricted device, and including the derived network address in a packet which further includes the data of the data frame; second determination means for determining, from the reception quality of the frame, a delay for transmitting the packet; and transmission means for transmitting the packet towards a destination device in the network after the delay. - View Dependent Claims (16, 17, 18, 19, 20)
