環型無線網狀網路之能量效益之模擬研究
Simulation Study of Energy Efficiency in a Ring-based Wireless Mesh Network
摘要
無線網狀網路 (WMN) 是一個有前途的解決方案來支持無處不在的寬帶服務｡ 在環狀式無線網狀網路中傳送功率和傳送距離影響了其重要的幾樣因子,包括系統的吞吐量和功率消耗｡本文探討能量效率之多通道環狀式無線網狀網路｡我們提出一個簡單的頻率規劃在我們的環形無線網狀網路來提升能力｡ 我們也開發了一個實體層 (PHY) /媒體存取控制層 (MAC) 的跨層分析模型來評估無線網狀網路的吞吐量在考慮的載波偵聽多路訪問 (CSMA) 的MAC協議, 及在實體層中跳躍距離對傳輸速率的影響｡最後分析的結果將會用模擬來驗證 ｡我們將能得到重要的指南在我們的網路佈署上,第一點就是我們的系統涵蓋範圍必須是要被設計的,第二點,在我們設計的涵蓋範圍之後,每一環的寬度也必須被好好的設計來達到整體的能量效益。

The wireless mesh network (WMN) is a promising solution to support ubiquitous broadband services. The major factors include throughput and power consumption are impacted by transmitted power and transmitted distance in ring-based WMN. This paper investigates energy efficiency in multichannel ring-based WMN. We suggest a simple frequency planning in the proposed ring-based WMN to improve the capacity. We develop a physical (PHY) / medium access control (MAC) cross-layer analysis model to evaluate the throughput of proposed WMN, by taking account of the carrier sense multiple-access (CSMA) MAC protocol, and the impact of hop distance on transmission rate in the PHY layer. Analysis results will be validated by simulations. We will get the important guidance for network deployment, the first point is that our system coverage must be designed, and the second point, after the system coverage be designed, the width of each ring must also be properly designed to achieve the overall energy efficiency.
