Title:
加重累積予想伝送時間メトリックを用いてリンク品質ルーティングを行うためのシステムおよび方法
Document Type and Number:
Japanese Patent JP4672452
Kind Code:
B2
Abstract:
A system and method for link quality routing uses a weighted cumulative expected transmission time path metric. A system for routing in a multi-hop ad hoc network, and a method for measuring the link quality of a route in the network, include assignment of a weight to a link in accordance with an expected transmission time of a packet over the link, and a combining of individual link weights for a route into a path metric. The path metric accounts for interference among links that use a shared channel. In the calculation of the path metric, the expected transmission times of links that interfere with one another are added, while the expected transmission times for non-interfering links are considered separately.
