以預先通知機制解決無線隨意網路下暫時性收訊死角問題

Abstract

本篇論文提出以預先通知的方法解決無線隨意網路下暫時性收訊死角問題,修改 要求傳送/允許傳送 交換機制通知參與競爭的節點他們在接收端的暫時性收訊死角範圍內.接著,修改退後機制減少頻道閒置的時間.模擬結果顯示,提出的方法是有效的.

In this thesis, we present a pre-notification method for solving deafness problem in wireless ad hoc networks. The RTS/CTS exchange scheme is modified to inform the contending stations that the receiver is deaf to them. Then, we modify the backoff scheme to lower the channel idle time. Simulation results are given to show the effectiveness of the proposed approach.
