| 摘 要： | 在Ad-Hoc无线网络中,激励机制能提高网络的性能,但“迁移率”的因素却被忽略了。允许节点有组织地相互移动,动态生成激励机制,能明显改善网络性能。现利用节点位置参与到被严格强制的激励机制的无线网络中。通过博弈理论,研究不同的激励机制的量化性能。结果表明:若允许用户选择自身位置,网络性能呈现明显衰变。此外,用户的最佳策略是网络拓扑结构或是紧束一团,或是分散成一条链。

| Abstract: | Incentive mechanisms can promote cooperative behavior in the network.But an important factor has been consistently neglected from such "mobility".By allowing nodes to move strategically in the network,the dynamics generated by an incentive mechanism can change significantly.In this paper,we consider node position as the strategy of a user that participates in an ad-hoc network where an incentive mechanism is strictly enforced.Using game theoretic models,we perform a qualitative study of the effect of different incentive mechanisms and show that if users are allowed to strategically choose their positions in the system,network performance degrades significantly.Otherwise,our results indicate that the best strategies for the users lead to topologies where the nodes are either tightly clustered together or spread into a chain. |
