Nodes in a network often store and serve content to other nodes. However, each has a finite capacity and if requests for content exceed the capacity then queries fail. It is generally not possible for a priori predictions of load demand because at given times some content may suddenly become popular and at others hardly requested at all. Hence over a given(More)
Many peer-to-peer (P2P) applications require that nodes behave altruistically in order to perform tasks collectively. Here we examine a class of simple protocols that aim to self-organise P2P networks into clusters of altruistic nodes that help each other to complete jobs requiring diverse skills. We introduce a variant (called ResourceWorld) of an existing(More)
Recent work has shown how socially inspired mechanisms developed within social science simulations can be applied to a number of application domains in distributed systems engineering. Here we proposed a general mechanism based on an evolutionary " group selection " process in which individual entities (agents, nodes or components) dynamically copy the(More)
