Am working on a game-theory approach that Prof. Leung Ho-fung developed, currenly. One of its applications could be cloud-node tracking at first in my guessing; still in the mist. Actually, the problem of resource allocation is not hot in cloud computing that is easy to forward overloaded requests to sparse resources that can accept more tasks: When your servers work at noon with heavy tasks, you have other servers working on the other side of the Earth manage them, where it is midnight. Jesus, we are losing problems to tackle as technology goes on fast. But, still we have new issues in this area... What is that? Anyway, I have found another problem to think about with this game approach in ecoinformatics. This looks good to me, somehow.
