HIERARCHICAL COMMUNICATION SYSTEM PROVIDING INTELLIGENT DATA, PROGRAM AND PROCESSING MIGRATION
First Claim
12. A communication network having a mobile terminal device configured with a wireless transceiver, said communication network comprising:
- a data source;
a plurality of access devices being arranged to provide a communication pathway between said mobile terminal device and said computing device; and
at least one of said plurality of access devices being configured to monitor communication traffic through the at least one of said plurality of access devices and to selectively store for future forwarding requested data so as to shorten the communication pathway from the data to said mobile terminal device.

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.

36-1. The communication network of claim 32 wherein said code processing circuit of said at least one of said plurality of access devices compares said received signals to stored image signals located in an image database to decode said received signals, and, if unable to find stored image signals which correspond to said received signals, performs a decode algorithm to decode said received signals.
-
37-2. The communication network of claim 36 wherein said code processing circuit of said at least one of said plurality of access devices updates said image database by storing the received signals if the performance of the decode algorithm is successful.
-
38. A processing device in a communication network, said having at least one two-dimensional code reading device configured with a first wireless transceiver, said processing device comprising:
-
a second wireless transceiver for receiving signals representative of two-dimensional images captured by a two-dimensional code reading device; a code processing circuit for decoding the signals received from the two-dimensional code reading device; and said code processing circuit delivering to the two-dimensional code reading device via said second wireless transceiver an indication of successful image decoding. - View Dependent Claims (39, 40, 41, 42, 43, 44)
