In this paper, we propose a new routing algorithm which calculates bandwidth-delay constrained routes in the fast and efficient manner. The algorithm is designed for the software-defined backbone networks, where the control plane is separated from the data plane and logically centralized. Besides providing the required quality of service (QoS), the algorithm aims to maximize utilization of network...
Wireless Mesh Networking is a continuous growing technology that can be used used for several application scenarios, such as military tactical operations, etc. in next generation wireless networks. The IEEE 802.11s Standard defines the procedures that wireless nodes follow in order to interconnect and create a Wireless Local Area Network (WLAN) mesh network. It, also, defines the routing protocol...
In this paper, we propose a cross layer optimization technique for video transmission in multi-radio Wireless Mesh Networks (WMNs). WMNs are used as back haul to connect various networks such as Wi-Fi, Wi-MAX etc. to the internet. The presence of multiple radios in this networks increases the capacity but introduces an interference. Thus, designing a better routing metric to find optimal path is an...
This paper proposes an improved mesh path selection protocol for QoS support in wireless mesh network, while avoiding the inherent problems of proactive and reactive path selection elements. The proposed ‘Advanced Selective Greedy’ (SelG+) path selection protocol operates in two phases. In the first phase it constructs a set of potential forwarders for every mesh stations. In the second phase during...
In the recent years, Wireless Sensor Networks (WSNs) have become a great field of interest for scientific community. This kind of network provides a panoply of applications in different areas of human life. However WSNs must ensure the quality of service (QoS) to give the requested performance for the final user. Among different issues presented in the literature to provide high QoS, multipath routing...
Cognitive Radio Ad-Hoc Network (CRAHN) is an emerging class of mobile ad hoc networks that provides each network node with a list of available channels. It is expected that the available routing protocols and metrics for traditional ad-hoc networks are not suitable for CRAHN in the environment of topology changes and different level of user mobility interference situations. Therefore, to achieve more...
