具有固定中继节点多跳小区结构

Analysis on Multi-hop Cellular Architecture with Fixed Ralay Node

为了在低发射功率的前提下扩展蜂窝小区的覆盖范围,本文基于多跳通信模式,提出由中心基站负责固定中继节点接入,移动节点通过固定中继节点的多跳中继而连接基站的网络结构,即接人式多跳小区结构。此结构提供了在低成本条件下完成区域覆盖的方法。对该小区结构的覆盖特性进行了分析,结果显示具有3个或4个固定中继节点的多跳小区结构可以有效地实现基站覆盖范围的扩展。

In order to expand the area coverage of cellular communication scheme, a multi-hop cellular architecture, i. e. system under low transmission power, based on the multi-hop an access multi-hop architecture, is proposed, where the central base station only has access points to fixed multi-hop relay nodes, and the mobile stations communicate with the base station by the relay of the fixed nodes. With this architecture, a method for covering the service area with low cost is provided. The characteristic analysis on area coverage is given. The results show that the multi-hop cellular architecture with 3 or 4 fixed multi-hop relay nodes is advantageous to efficiently expand the area coverage of the base station.
