On Properties of Game Theoretical Approaches to Balance Load Distribution in Mobile Grids
Mobile devices can be integrated into grids to access grid resources but also to provide resources, such as CPU cycles or memory, building mobile grids. To exploit the potential of mobile grids, we propose an opportunistic job scheduling approach to harness cycles among mobile devices. Mobile nodes decide autonomously and locally which job to take by matching the job’s requirements against their capabilities and coordinate with one another by means of shared job queues. A prototype implementation has been presented in previous work. In this work, we introduce selfish nodes which are expected to occur among mobile devices with limited energy sources. To react to selfishness, we introduce three strategies of game theory, that are, Tit For Tat (TFT), generous TFT, and Go-By Majority (GBM), to our approach and investigate the emerging behavior of the system by means of simulation. First results show, that the TFT and GBM implementations converge fast to fully selfish systems, while generous TFT exhibits self-healing characteristics.
