Embodiment Construction

[0031] Described here is the process used by devices to communicate over a wireless network using frequency hopping. Figure 1 illustrates an exemplary wireless network 10 over which this process may be performed. Depending on the process, devices on or entering the network may communicate on one or more channels. To allow this communication, frequency hopping data is exchanged between devices as they enter the network. As explained below, frequency hopping data describes how each device communicates using frequency hopping, enabling the devices to schedule communications for the appropriate frequency, time of day, and duration. Frequency hopping as used here increases the capacity of the network because it allows network traffic to overlap without significantly increasing congestion and packet loss.

[0032] Before explaining how to use frequency hopping in a wireless network, we first illustrate an example of a wireless network and how to set it up.

Abstract

A first device communicates with a wireless network that includes nodes that are active for predefined activation times and that are at least partially dormant when not active. The communication method includes identifying a start of communication via a message that exceeds a maximum activation time of nodes on the wireless network by a factor N, where N is equal to at least a maximum number of frequencies on the wireless network, and exchanging information with a second device comprising a node on the wireless network that is within a transmission range of the first device, where the information is exchanged following the message and includes frequency hopping data for the second device.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 60 / 686,127, filed June 1, 2005, and US Provisional Application No. 60 / 724,343, filed October 6, 2005. The entire contents of US Provisional Application No. 60 / 686,127 and US Provisional Application No. 60 / 724,343 are hereby incorporated by reference as if set forth in their entirety. technical field [0003] The present application relates generally to communications over wireless networks, and, more particularly, to communicating over wireless networks utilizing frequency hopping. Background technique [0004] Ad hoc (ad hoc) wireless networks (mesh networks) are ad hoc networks in which network devices themselves establish communication links with each other. Wireless networks can be used in different settings. For example, a wireless network can be established between the monitoring and control device and the host computer. [0005] In one exam...
