A key challenge to communications on the network-centric battlefield is that the end-devices must utilize limited resources to support the mission operations. This requires the devices to conserve resources by avoiding the reception, transmission, and processing of unusable information, a capability not currently available. Todays networks are completely unaware of the capability of their end-points. Being dumb pipes, they cannot optimize traffic to match the capabilities and requirements of their end devices. With such a problem present, the World Wide Web Consortium W3C introduced the concept of device independence. The idea is to let the client send the request with information associated with the end device. The purpose of this information is to provide information that may be needed to allow the final response to be repurposed to the capabilities of the client. The request and the delivery context flow from the client, through any intermediaries to the server. The server can use the appropriate repositories of content in constructing the response to the request. The goal of a Device-Aware Network DAN is to match the information delivered to the capability of the end device, thereby optimizing the network resource usage. To efficiently transmit information on a DAN, the capabilities and conditions of an end-device must be defined in advance to adapt the data format a device profile. This thesis discusses the current standards for device profiling and gives a comparison of these standards. It then identifies a suitable standard that can serve as the starting point for creating a device profile request scenario for a DAN. Currently, the available standards for device profiling are Composite CapabilitiesPreference Profile CCPP developed by the W3C, User Agent Profile UAProf developed by the WAP forum, SyncML developed by the mobile technology industry, and Universal Plug and Play UPnP developed by Microsoft.
