研究了无线网络中移动用户的跟踪策略。为了节省使用无线链路的成本，移动用户不应该在跨越相邻小区边界时更新他们的位置。本文重点研究了移动用户在何时何地做出更新决策的三种自然策略：基于时间的策略、基于移动次数的策略和基于距离的策略。我们既考虑了无记忆的运动模式，也考虑了沿环状排列的细胞拓扑的具有马尔可夫记忆的运动。我们分析了这三种策略在这些运动下的表现，并展示了这三种策略之间的表现差异。
Tracking strategies for mobile users in wireless networks are studied. In order to save the cost of using the wireless links mobile users should not update their location whenever they cross boundaries of adjacent cells. This paper focuses on three natural strategies in which the mobile users make the decisions when and where to update: the time-based strategy, the number of movements-based strategy, and the distance-based strategy. We consider both memoryless movement patterns and movements with Markovian memory along a topology of cells arranged as a ring. We analyze the performance of each one of the three strategies under such movements, and show the performance differences between the strategies.
