Hierarchical communication system providing intelligent data, program and processing migration
First Claim
1. A communication network, comprising:
- a plurality of access devices, the plurality of access devices comprising a first access device and a second access device, the first access device supporting wireless communication, the second access device accessed via the first access device,wherein at least one of a code and data is retained in the second access device,wherein the at least one of the code and the data is requested a plurality of times by the first access device, andwherein a copy of the at least one of the code and the data migrates to the first access 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.
