    Abstract:  本願発明は、受信電力(RSSI)の変動により伝搬路が変動しても、安定した中継経路を構築可能な通信システム等を提案する。無線バックホールシステムにおいて、コアノードを根とするツリー構造の通信経路を構築するときに、各スレーブノードにおいて、直近のリセット・ルーティング・パケットを受信してから、同じ送信元ノードより受信したn個のルーティングパケットの受信電力の逐次平均などを用いて、この送信元ノードを、ツリー構造における親とするか否かを決定する。受信電力は一般に対数正規分布に従うことから、特に逐次平均を用いることにより、漸近的に安定した中継経路を獲得することができる。

    Abstract: By introducing a novel parameter common to all links along the entire multihop route it is possible to more flexibly allocate, for each of a number of the links, a set of three interdependent link transmit parameters representative of a) link transmit energy, b) link transmit time or link transmit bandwidth or link code word consumption, and c) link transmit power. Basically, the common parameter is determined based on a given end-to-end (ETE) transmit parameter constraint for the entire multihop route (S 1). The idea is then to assign or allocate, for each considered link, the three interdependent link transmit parameters based on the common parameter and local link characteristics (S2). In this way, all three link transmit parameters may (and generally will) be different between at least two links on the route when the links have different link characteristics, assuming that each link transmit parameter is also dependent on the local link characteristics. Preferably, the common parameter is determined in the process of optimizing a given objective ETE function.
