Delivery of high-quality streaming services over multi-hop wireless mesh networks (WMNs) is a challenging research problem because of quality fluctuation and interference of wireless links in WMNs, as well as strict throughput, delay, and reliability requirements of streaming applications. In this paper, we propose a Network Assisted Peer-to-Peer (NAP2P) system for file-based media streaming services...
Wireless mesh networks usually deploy multiple gateways to enhance the capacity. This paper studies how to maintain forwarding paths in 802.11s wireless mesh network. A Multi-Gateway Multipath routing protocol (MGMP) is proposed to explore path diversity. MGMP constructs multiple paths between source and destination using a proactive tree architecture as HWMP. In order to make MGMP more efficient,...
Wireless mesh networks are being widely deployed around the world as a mean to provide low-cost access to the Internet. An orthogonal evolution in computer networking has been the rise of peer-to-peer communication. Structured peer-to-peer overlay networks have been used as platform for building large-scale distributed network applications such as file sharing. It is of interest to build those distributed...
Optical-Wireless (FiWi) access network is a newly emerged access network architecture which integrates passive optical networks (PONs) with wireless mesh networks (WMNs) to provide the ubiquitous, low cost, high bandwidth last mile Internet access. Though the PON subnetwork of FiWi network can provide high bandwidth, the interference in the wireless subnetwork still limits the throughput of FiWi network...
IEEE 802.11-based backbone mesh networks comprise of static wireless mesh routers (WMRs) which create a wireless multihop backbone to provide high-speed last-mile wireless Internet access to communities. Specialized WMRs called gateways provide the interconnection between the mesh network and fixed IP networks. Mesh routers perform backhaul routing and may additionally serve as access points (APs)...
Traditional hop-by-hop dynamic routing makes inefficient use of network resources as it forwards packets along already congested shortest paths while uncongested longer paths may be underutilized. To maintain network-wide load balancing, we propose Autonomous Network management with Team learning based Self-configuration (ANTS) which attempts to manage a feasible route for traffic flow with QoS constraints...
Noting that the optical part of a hybrid wireless- optical broadband access network (WOBAN) has high capacity, we need to enhance the capacity for wireless access using a low-cost solution. Our prior work developed a solution where each wireless node was equipped with a single radio. Deploying multiple radios, say two, at each node will improve the performance of wireless access, but this will also...
We study scalable, distributed, and adaptive routing algorithms for communication networks. The back-pressure algorithm introduced in [21] is a well-known distributed and adaptive routing/scheduling algorithm where nodes only need the queue length information of neighboring nodes to make routing decisions, and packets are adaptively routed in the network according to congestion information, which...
Approaches to building an intelligent consumerfriendly network have evolved over time from centralized switch-based to router- and serverbased Internet architectures. We propose to drive this evolution further with a new highly scalable architecture that provides features to users derived from the computational and networking capabilities of very large populations of sophisticated terminals. This...
