Despite recent excitement generated by the peer-to-peer (P2P) paradigm and the surprisingly rapid deployment of some P2P applications, there are few quantitative evaluations of P2P systems behavior. The open architecture, achieved scale, and self-organizing structure of the Gnutella network make it an interesting P2P architecture to study. Like most other P2P applications, Gnutella builds, at t...

This paper addresses an NP-hard problem of designing a network topology with maximum (s, t) reliability subject to given constraints, such as the computer centers location (nodes), their connecting links reliability and cost, and the maximum budget cost to install the links. Cost is a major issue in the network design, and thus the problem is applicable for networks requiring maximized reliabil...

In this paper, we consider the problem of building a secure network against node conspiracy attack that based on network segmentation. As we know, network coding has demonstrated its great application prospects in wireless sensor network (WSN) transmission. At the same time, it is facing a variety of security threats, especially conspiracy attack. In existing research, secure coding design stra...

Sensor nodes in Wireless Sensor Network (WSN) are responsible for sensing the environment and propagating the collected data in the network. The communication between sensor nodes may fail due to different factors, such as temporal variations of the wireless channel, interference, hardware failures, and energy depletion. Hence, robust design of WSNs in order to be resilient to such failures is ...

Various kinds of broadcast services, such as TV distribution and Near Video-On-Demand, will be introduced into the B{ISDN tra c. These services need wide bandwidth since they have moving images. Therefore, broadcast services will occupy a large part of the B{ISDN tra c. However, the nationwide topologies of the conventional telecommunication network are designed for point-to-point (P-P) service...

Neural networks, especially in nonlinear system identi£cation and control applications, are typically considered to be blackboxes which are dif£cult to analyze and understand mathematically. Due to this reason, an indepth mathematical analysis offering insight into the different neural network transformation layers based on a theoretical transformation scheme is desired, but up to now neither a...

Advances in sensor technology and computer networks have enabled distributed sensor networks (DSNs) to evolve from small clusters of large sensors to large swarms of micro sensors, from fixed sensor nodes to mobile nodes, from wired communications to wireless communications, from static network topology to dynamically changing topology. To design these networks, the factors needed to be conside...

This paper considers wireless multicast networks where network coding (NC) is applied to improve network throughput. A novel joint topology and cross-layer design is proposed to maximise the network throughput subject to various quality-of-service constraints, such as: wireless multicast rate, wireless link capacity, energy supply and network lifetime. Specifically, a heuristic NC-based link-co...

Present work introduces two network design algorithms for planning UMTS (Universal Mobile Telecommunication System) access networks. The task is to determine the cost-optimal number and location of the Radio Network Controller nodes and their connections to the Radio Base Stations (RBS) in a tree topology according to a number of planning constraints. First, a global algorithm to this general p...
