摘要

繞徑協定在無線電隨意行動網路主要是解決未註冊使用者(SUs)和其他未註冊
使用者之間的通訊。未註冊使用者(SUs)透過隨意行動網路連接註冊的頻譜，但是會
因為註冊使用者(PUs)的出現而被中斷未註冊使用者(SUs)的之間通訊。多條路徑繞
徑協定提供更可靠的通訊，設計多條路徑繞境協定必須計算未被註冊使用者(PUs)
佔用頻譜的機率、資料吞吐量和未註冊使用者(SUs)服務品質。在這篇論文中，我們
考慮未被註冊使用者(PUs)佔用頻譜的機率而且分配每條連結的通道。這些未被註冊
使用者(PUs)佔用頻譜的機率去計算所有路徑的頻寬以及選擇適合的多條路徑。透過
模擬，所提出多條路徑繞徑協定，在相對較大預期頻寬量下傳輸更多資料，而且提升未註冊使用者(SUs)的服務品質。

Routing protocol in cognitive radio ad-hoc networks is mainly to dealing with unlicensed users (called secondary users, SUs) communicating with other secondary users. Secondary user through ad-hoc networks connection on licensed spectrum bands, but the ad-hoc connection may be interrupt when licensed users (called primary users, PUs) are appear, the ad-hoc connection may be interrupted. Multi-path routing protocol is a way to improve the reliability of connections. The design of multi-path routing protocol for cognitive radio ad-hoc networks must account the probability of spectrum hole unoccupied by PUs, data throughput and quality of service (QoS) of SU. In this paper, we consider the probability of spectrum hole unoccupied by PUs and allocating every channel of links. The probability of spectrum hole unoccupied by PUs are used to calculate all paths expected transmission bandwidth choose the suitable paths. Through simulation, the proposed multi-path routing protocol transmits large amounts of data in the relative maximum expected transmission bandwidth and improves quality of service (QoS) of secondary users.
