Abstract

We present a novel TDMA-based medium access control (MAC) protocol for wireless sensor networks. Unlike conventional MAC protocols, which function independently of the application, we introduce an adaptive, information-centric and lightweight MAC (AI-LMAC) protocol that adapts its operation depending on the requirements of the application. We also present a completely localised data management framework that helps capture information about traffic patterns in the network. This information is subsequently used by AI-LMAC to modify its operation. The data management-framework can additionally be used for efficient query dissemination and query optimisation. We present preliminary results showing how the MAC protocol efficiently manages the issues of fairness and latency.
AI-LMAC:用于无线传感器网络的自适应、以信息为中心的轻量级MAC协议
提出了一种基于tdma的无线传感器网络介质访问控制(MAC)协议。与独立于应用程序的传统MAC协议不同,我们引入了一种自适应的、以信息为中心的轻量级MAC (AI-LMAC)协议,该协议根据应用程序的需求调整其操作。我们还提出了一个完全本地化的数据管理框架,帮助捕获有关网络中流量模式的信息。AI-LMAC随后使用这些信息来修改其操作。数据管理框架还可以用于有效的查询传播和查询优化。我们提出的初步结果显示MAC协议如何有效地管理公平性和延迟问题。
