基于TDMA的三出口线性拓扑多跳无线传感器网络调度
TDMA-based scheduling for multi-hop wireless sensor networks with 3-egress gateway linear topology
摘要：
研究了具有三出口网关线性拓扑结构的多跳无线传感器网络的分组传输调度问题。每个节点在每一个循环周期内生成一个数据包，并将其转发到边界处的任意一个网关。我们专注于集中管理的时分多址（TDMA）为基础的时隙分配和静态时隙分配和基本的冗余传输，以减少和恢复数据包丢失的数据包传输调度框架的设计。我们提出了三个一般的路径模型，这将代表所有可能的变化，这种拓扑结构，并推导出一个全球静态时隙分配模型，以最大限度地提高理论概率，所有的数据包被成功地交付到一个网关在一个周期内。
英文摘要：
Packet transmission scheduling on multi-hop wireless sensor networks with 3-egress gateway linear topology is studied. Each node generates a data packet in every one cycle period and forwards it bounded for either of gateways at edges. We focus on centrally-managed Time Division Multiple Access (TDMA)-based slot allocations and provide the design of a packet transmission scheduling framework with static time-slot allocation and basic redundant transmission to reduce and recover packet losses. We proposed three general path models, which would represent all possible variations of this topology, and derived a global static time-slot allocation on each of models to maximize the theoretical probability that all packets are successfully delivered to one of the gateways within one cycle period.
