New applications where anyone can broadcast video are becoming very popular on smartphones. With the advent of high definition video, ISP providers may take the opportunity to propose new high quality broadcast services to their clients. Because of its centralized control plane, Software Defined Networking (SDN) seems an ideal way to deploy such a service in a flexible and bandwidth-efficient way...
Multicasting protocols can be used to improve the efficiency of the wireless links in Mobile Ad hoc Networks when sending multiple copies of messages from multiple sources to multiple receivers. In this paper, a Source initiated Mesh and soft-state based QoS Probabilistic multicast routing protocol (SQMP) for MANETs is proposed. SQMP is inspired from the ant colony's route finding algorithm through...
In this paper, we clarify problems related to QoS guarantee and multicasting on the Internet, and suggest principles of solving the problems and implementing QoS guarantee and multicasting at the same time by means of integrating multicasting and QoS guarantee for a New-Generation Network (NwGN). These principles also simplify QoS/multicast routing protocols.
Handoff management plays an important role in wireless mesh networks (WMNs) in delivering Quality of Service to mobile users. Inter-gateway (across subnets) movement in WMNs usually requires the handoff support from multilayers and thus causes nonnegligible delays and packet loss. Previous solutions on handoff management in infrastructure WMNs mainly focus on intra-gateway mobility (e.g., single gateway...
In this paper we propose a new scheme named Differentiated QoS Multicast (DQM) based on the Source Specific Multicast (SSM) model in order to provision limited qualitative QoS channels for supporting heterogeneous end users. Based on Service Level Agreements, both sources and group members should select a specific QoS channel available from the network for group data transmission, and arbitrarily...
In this paper we have proposed HRSQM, heterogeneous receivers supporting QoS multicast, which is a distributed protocol that creates multicast tree for receivers with heterogeneous QoS requirements. It relies only on local states and does not use any global state. Furthermore, through exhaustive search and carefully selecting branch to connect the new node to the tree, the efficiency of tree is always...
