在无线传感器网络中，由于sink移动引起的信息延迟是有界的，本文利用sink移动来延长网络寿命。我们建立了一个统一的框架来分析这种联合汇的迁移和路由问题。我们提供了一个通用的数学模型，并捕获了多种问题，例如sink mobility， routing， delay等。我们讨论了引申子问题，并给出了它们的有效解。然后，我们对这些解进行了推广，并提出了原点问题的多项式时间最优算法。在模拟中，我们展示了使用移动接收器的好处。我们还展示了延迟界对网络生存期的影响。
This paper exploits sink mobility to prolong the network lifetime in wireless sensor networks (WSNs) where the information delay caused by moving the sink should be bounded. We build a unified framework for analyzing this joint sink mobility and routing problem. We offer a mathematical modeling that is general and captures diversified issues, e.g. sink mobility, routing, delay, etc. We discuss the induced subproblems and present efficient solutions for them. Then, we generalize these solutions and propose a polynomial-time optimal algorithm for the origin problem. In simulations, we show the benefits of involving a mobile sink. We also show that the impact of the delay bound on the network lifetime.
