第六章 結論與未來研究方向
6.2 未來研究方向
未來研究與思考上,本論文在量測環境中僅使用三種間隔距離進行多媒體資 訊之傳輸實驗,因此在 60 公尺之後相關語音品質皆已無法維持在一般大眾所能 接受的分數,若能夠在 60 公尺與 80 公尺之間進行較密集的量測更能夠得到完整 的數據結果,另外在 TI CC2530 天線設計上使用陶瓷天線且在製程中已嵌入於電 路板中,相較於外接天線的傳輸距離上有明顯不足且具有指向性,若在天線上能 夠外接將有助於傳輸距離的提升。
此外在影像傳輸上,雖然 MRSC 能夠提供 150kbps 的網路吞吐量(Throughput),
但在 150K 壓縮率的門檻中還稍嫌不足,應該進行有效吞吐量(Goodput)量測,方 能更加準確的計算如何達到即時影像傳輸的門檻,由於本論文尚未將影像於無線 感測網路中進行傳輸,因此在未來研究上可以針對本論文所提之傳輸機制進行多 媒體影像之傳輸,並且根據不同距離實際量測與分析封包遺失率針對影像品質所 造成的影像。
