Two main problems prevent the deployment of peer-to-peer application in a wireless sensor network: the index table, which should be distributed stored rather than uses a central server as the director; the unique node identifier, which cannot use the global addresses. This paper presents a multi-level virtual ring (MVR) structure to solve these two problems. The index table in MVR is distributed stored...
In sufficiently large heterogeneous overlays message loss and delays are likely to occur. This has a significant impact on overlay routing, especially on longer paths. The existing solutions to this problem rely on message redundancy to mask the loss and delays. This incurs a significant bandwidth cost. We propose the forward feedback protocol (FFP) which only routes a single copy of the message and...
Wireless mesh networks are being widely deployed around the world as a mean to provide low-cost access to the Internet. The high capacity at mesh routers nodes allows applications such as real time multicast over WMNs. In light of the slow development of IP multicast and the rise of peer-to-peer communication, implementing multicast capability at the application layer is imminent. QoS support for...
Peer-to-Peer (P2P) technologies are considered as one of the fundamental technologies for the next generation Internet. P2P systems are classified into unstructured P2P systems or structured P2P systems depending on their topological structure of network. Most structured P2P systems are based on Chord protocol that is designed by using Distributed Hash Tables (DHTs). However, some issues have not...
