における制御通信削減を目的とした 経路制御手法の機能評価

中塚 優太

近年,モバイル端末の増加に伴って通信トラヒックが増加している.そこで注目され ているのが,通信エリアの拡大・縮小が可能な無線メッシュネットワークである.しか し,実際に無線メッシュネットワークを構築するための機器やソフトが出揃っていると は言えない.

そこで本研究では,本研究グループで提案されているWMNにおける制御通信削減を 目的とした経路制御手法MBCR を実環境上でのAPで運用可能とするために必要とす る詳細な仕様を決めるとともに,実機でMBCR の機能を持ったAPを実装して機能評 価を行った.結果として,ユーザが文字列の送受信をするには問題のない速度を計測で きる無線メッシュネットワークを構築することに成功したが,動画などの容量の大きい ファイルを送受信するために十分と言える速度を計測することはできなかった.

Abstract

Functional evaluation of routing method for control communication cost in WMN

In recent years, as the number of mobile terminals has increased, traffic is increasing.

WMN is attracting attention because it can expand and contract communication area.

However, it can not be said that equipment and software for actually constructing a wireless mesh network are present.

Therefore, in this research, we decided the detailed specifications required to enable MBCR of routing control method aimed at reduction of control communication in WMN proposed by this research group in Access Point on real environment, We implemented an application with MBCR function on the actual machine and evaluated the function.

As a result, we succeeded in constructing a wireless mesh network that can measure the speed at which character transmission / reception is not a problem, but it was not able to measure the speed suitable for transmitting and receiving large capacity files such as moving images.
