Mobile Ad-Hoc Networking on Android Devices.

摘要

Mobile devices provide civilians with a convenient way to communicate on a day-to-day basis. However, their centralized infrastructure can be interrupted at critical times such as during natural disasters. While this cellular infrastructure may not be available in environments, such as the battlefield, these ubiquitous devices could exploit ad-hoc mode communication to be of use. The Army has identified several military applications for ad-hoc networks of mobile devices, including communication between dismounted Soldiers, facial recognition, and situation awareness. Many of these applications require more capabilities than most mobile devices possess, or would prove to be a burden on the limited battery lives of these devices. Thus, offloading computation to a more capable machine has been identified as a means to make these devices useful while mitigating their weaknesses. This has lead Army researchers to develop novel algorithms to improve the offloading process. Although these algorithms have been tested via simulation, a working implementation is necessary to fully evaluate them. This report discusses the state of ad-hoc mode communication on Android devices, and describes the procedure for enabling ad-hoc mode, which is often not available by default. It goes on to describe techniques for studying multiple aspects of the network and its behavior.
