In order to solve the problem that the structure of P2P network's logical network and physical topology do not match at a large extent, information of resources' searching are time-consuming, we propose an improved P2P chord model which was based on the IP-LCO algorithm. The adoption of IPv6 addresses can solve the unmatched problem, and LCO algorithm can quickly location the resources' network node...
We address multi-radio networks, i.e., wireless networks where the nodes are equipped with multiple air interfaces. We analyze, both analytically and via simulation, various gains that the multi-radio environment can provide. First we investigate the gain in network connectivity by modeling the topology of a multi-radio network by a multigraph. The gain is captured by introducing the novel graph theoretic...
The network-centric future force must support a large and diverse group of communication nodes. While much network design in networks such as future combat systems (FCS) and warfighter information network- tactical (WIN-T) can be done using existing TCP/IP protocols, there are important performance limits when the network conditions become more extreme (e.g., highly mobile or dense). A solution for...
In a telecommunication network it is essential to provide virtual connections between peering nodes with performance guarantees such as minimum throughput, maximum delay or loss. Critical services in telecommunication network should be continuously provided even when undesirable events like sabotage, natural disasters, or network failures happen. The design, construction and management of network...
In order to improve scalability and reduce maintenance overhead for structured peer-to-peer systems, researchers design optimal architectures with constant degree and logarithmical diameter. The expected topologies, however, require the number of peers to be some given values determined by the average degree and the diameter. Hence, existing designs fail to address the issue due to the fact that (1)...
Server selection plays an essential role in content replication networks, such as peer-to-peer (P2P) and content delivery networks (CDNs). In this paper, we perform an analytical investigation of the strengths and weaknesses of existing server selection policies, based initially on an M/G/1 processor sharing (PS) queueing-theoretic model. We develop a theoretical benchmark to evaluate the performance...
In this paper, the performance of peer-to-peer (P2P) file sharing service based-on flooding search algorithm is analyzed. We focus on six types of four-terminal four-router physical network, and investigate the impact of topology inconsistency and flooding search on the file retrieval performance. The analysis model is based on a two-layer queueing network in which both logical and physical topologies...
