| Abstract: |
We examine the issue of cooperation between mobile nodes for the retrieval
of information objects from fixed points of a network (e.g., digital
announcement boards, interactive maps, sensor data for traffic, etc. in a
city environment). We consider that the mobile nodes have either common or
different interests for information objects. In the first case, we study a
scheme for distributing the information retrieval tasks between a group of
nodes that have the same interests. In the second case, we study incentives
(in the form of bilateral object exchanges) that are necessary to achieve
cooperation. The problems that arise are treated using concepts from game
theory, and we derive useful conclusions on the plausibility and efficacy of
the cooperation mechanisms. |
