“…This anticipation allows the routing protocol to compensate the delay due to the computation and dissemination of the metrics. We considered ETX [5] (Expected Transmission Count) and ETT [6] (Expected Transmission Time), but we combine their computation to our prediction algorithm. Through a large set of simulations and scenarios, we have shown that our method improves significantly the PDR.…”

“…A lot of metrics have been proposed in literature [18]. In this paper, we focus on the most popular metrics, ETX [5] and ETT [6], which have been shown among the most efficient [18]. Moreover, we present the LD (Link Duration) metric in detail as it will be used in our simulations.…”

“…Our contributions deal with a new metric calculation method to manage the mobility problem. We consider classical metrics, in particular ETX [5] (Expected Transmission Count) and ETT [6] (Expected Transmission Time), but we combine their computation to our prediction algorithm. We focus on mobile ad hoc networks but it does not prevent its use in other contexts.…”

Abstract. When a node is moving in a wireless network, the routing metrics associated to its wireless links may reflect link quality degradations and help the routing process to adapt its routes. Unfortunately, an important delay between the metric estimation and its inclusion in the routing process makes this approach inefficient. In this paper, we introduce an algorithm that predicts metric values a few seconds in advance, in order to compensate the delay involved by the link quality measurement and their dissemination by the routing protocol. We consider classical metrics, in particular ETX (Expected Transmission Count) and ETT (Expected Transmission Time), but we combine their computations to our prediction algorithm. Extensive simulations show the route enhancement as the Packet Delivery Ratio (PDR) is close to 1 in presence of mobility.

Abstract-This paper focuses on the implementation and the verification of an interference aware routing scheme based on channel-load for multi-radio multi-channel wireless mesh network. Channel-load which is defined in IEEE 802.11k is channel consumption per time period of radio channel. Channel-load metric is able to recognize interference better than existing metrics in IEEE 802.11 networks. As a result, this routing metric achieves higher performance than other metrics in the environment with interference that has insufficient radio channel resources like wireless mesh network. Also, transmission of additional packets are not required to measure routing metric, and the status of wireless links is reflected accurately by using this metric, because it is calculated from channel busy time and measurement duration of profiling registers in the WALN interface. In this paper, we implemented the channel-load metric on WLAN mesh routers and verified the performance of the WLAN mesh network using this metric. The WLAN mesh network with the proposed routing scheme has improved both the throughput and the probability to select better route by about 30% than other schemes.
