Energy consumption has been a critical factor for mobile video applications. The quality of content delivery over wireless mesh networks consisting of such devices is also considered important. Existing energy-aware research and industrial effort focuses on reducing high-energy-consuming working periods of mesh devices at the expense of decreasing the quality of video content. This paper proposes...
This paper proposes a novel Medium Access Control scheme for wireless multi-hop Mesh networks using network-aware to adaptively detect the MAC maximum retransmission count and reduce collision probability of wireless channel. The proposed scheme can differentiate packet loss causes for wireless link by means of environment information and adjust the maximum retransmission count of MAC adaptively based...
Due to Wi-Fi Alliance (WFA)'s marketing, 802.11 became a universal solution for wireless connectivity. However, still a WLAN depends on wired infrastructure that interconnects the central Access Points (APs). To become independent of backbone networks leading to cheap deployments, the traditional single-hop approach needs to be replaced by Wireless Mesh Networks (WMNs). With 802.11s an integrated...
Wireless mesh networks (WMNs) have emerged as a key technology for next-generation wireless networking, due to independency of backbone networks. However, to make a WMN be all it can be, considerable research efforts are still needed. As the available MAC and routing protocols applied to WMNs do not have enough scalability as throughput drops significantly as the number of nodes or hops increases...
We develop a new wireless link quality metric, ECOT (Estimated Channel Occupancy Time) that enables a high throughput route setup in wireless mesh networks. The key feature of ECOT is being applicable to diverse mesh network environments where IEEE 802.11 MAC (Medium Access Control) variants are used. We take into account the detailed operational features of various 802.11 MAC protocols, such as 802...
Wireless mesh networks are primarily used to provide Internet access by sharing the Internet connections of a limited number of gateways. If traffic is routed in the mesh without considering load distribution, unevenly network congestion may arise and some gateways may rapidly get overloaded, which causes a significant reduction of the network capacity. To address this issue, in this paper we firstly...
