System and method for controlling communication in a multi-network environment
First Claim
1. A method for reducing interference, the method comprising steps of:
- transmitting a message from a first communication device using a first communication protocol, the message being formatted to inform a second communication device to refrain from communicating with the first communication device using the first communication protocol during a specified time period to avoid colliding with another communications signal of a second communication protocol.

Abstract
A hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. Copies of data, program code and processing resources are migrated from their source toward requesting destinations based on request frequency, communication link costs and available local storage and/or processing resources. Each appropriately configured network device acts as an active participant in network migration. In addition, portable two-dimensional (2-D) code reading terminals are configured to wirelessly communicate compressed 2-D images toward stationary access servers that identify the code image through decoding and through comparison with a database of images that have previously been decoded and stored.

9. A system in a first wireless communication device for controlling communication among a plurality of wireless communication devices which communicate in one or more networks, the system comprising:
-
a memory device for storing a plurality of communication protocols; and a control processor for selecting one of the plurality of communication protocols, wherein the control processor transmits a message to a second wireless communication device to reduce the probability of collision among the plurality of communication protocols. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A system for reducing interference, the system comprising:
one or more circuits for transmitting a message from a first communication device using a first communication protocol, the message being formatted to inform a second communication device to refrain from communicating with the first communication device using the first communication protocol during a specified time period to avoid colliding with another communications signal of a second communication protocol.
