On the performance of expected transmission count (ETX) for wireless mesh networks
The Expected Transmission Count (ETX) metric is an advanced routing metric for finding high-throughput paths in multi-hop wireless networks. However, it has been determined that ETX is not immune to load sensitivity and route oscillations in a single radio environment. Route oscillations refer to the situation where packet transmission switches between two or more routes due to congestion. This...
متن کاملRouting Metric of Expected Delay in Multi-Radio Multi-Channel Wireless Mesh Networks
—Many routing metrics have been proposed to improve the performance of wireless mesh networks (WMNs). Most of these routing metrics describe intra-flow and inter-flow interference respectively, which brings in adjustable parameters or results in non-isotonicity. However, the adjustable parameters, used to balance the intra-flow and inter-flow interference, are difficult to adapt to the network...
متن کاملEffective Routing Scheme through Network Load-aware Route Metric in Multi-rate Wireless Mesh Networks
In multi-rate wireless mesh networks, a mesh node can dynamically modify the data rate on a particular link, in response to the perceived SNR ratio between neighbor nodes. In such networks, existing route selection schemes use a link quality metric based on the expected amount of medium time it takes to successfully transmit a packet. However, these schemes do not take into account the status o...
متن کاملTheoretical Analysis of Route Expected Transmission Count in Multi-Hop Wireless Networks
In multi-hop wireless networks, communication quality depends on the route from a source to a destination. In this paper, we consider a one-dimensional multi-hop wireless network where nodes are distributed randomly and theoretically analyze the relation between communication quality and routing policy using a measure called the Expected Transmission Count (ETX), which is the predicted number o...
متن کاملA Unified Metric for Opportunistic Routing in Wireless Mesh Networks
In wireless mesh networks, the routing of packets from source to destination is crucial and challenging task. The wireless mesh networks find applications in disaster management, video on demand, intelligent, health care systems, etc. Various routing protocols exist in literature to improve the efficiency of the wireless mesh networks calculated in terms of reliability, cost, throughput, error ...
