Simplifying Cyber Foraging for Mobile Devices † ‡ Rajesh Krishna Balan , Darren Gergle , Mahadev Satyanarayanan , and James Herbsleb † Singapore Management University, ‡ Northwestern University, and Carnegie Mellon University rajesh@.sg, dgergle@, {satya, jdh} @ ABSTRACT One way to resolve this paradox is for a mobile device to perform Cyber foraging is the transient and opportunistic use of compute remote execution on a nearby compute server over a wireless link. servers by mobile devices. The short market life of such devices Cheap commodity machines widely dispersed for public use could makes rapid modification of applications for remote execution an act as compute servers for mobile devices in their vicinity. We important problem. We describe a solution that combines a “little refer to this transient and opportunistic use of resources as cyber language” for cyber foraging with an adaptive runtime system. We foraging. Although deployment of compute servers for public use is not imminent, our work addresses future environments where report results from a user study showing that even novice develop- ers are able to successfully modify large, unfamiliar applications in they may be as common as water fountains, lighting fixtures, chairs just a few hours. We also show that the quality of novice-modified or other public conveniences that we take for granted today. When and expert-modified applica
