The design of network topology is an important part of network design, since network topology is directly associated with network operational behavior, capacity, reliability, and cost. This paper is a tutorial paper concerned with illustrating how the optimization capabilities of genetic algorithms can be used to design suitable network topologies considering basic topology problems. Simple gen...

Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

In this paper, a new virtual leader following consensus protocol is introduced to perform the internal and string stability analysis of longitudinal platoon of vehicles under generic network topology. In all previous studies on multi-agent systems with generic network topology, the control parameters are strictly dependent on eigenvalues of network matrices (adjacency or Laplacian). Since some ...

This paper investigates reliability analysis of wireless sensor networks whose topology is switching among possible connections which are governed by a Markovian chain. We give the quantized relations between network topology, data acquisition rate, nodes’ calculation ability, and network reliability. By applying Lyapunov method, sufficient conditions of network reliability are proposed for suc...

Clustering is a crucial network design approach to enable large-scale wireless sensor networks (WSNs) deployments. A large variety of clustering approaches has been presented focusing on various aspect such as minimizing communication overhead, controlling the network topology etc. Simulations on such protocols are performed using theoretical models that are based on unrealistic assumptions lik...

Achieving a deep understanding of the Internet topology has proved very challenging since it involves solving difficult task, e.g. mapping the actual topology, characterising it and developing generation models that capture the fundamental properties. There are two categories of tools which were developed to deal with network topology, namely, topology generations tools and network/topology dis...

Cluster computing is becoming an accepted form of supercomputing in the academe, government and industries around the world. The Ateneo High Performance Computing Group (AHPCG) proposes a design for building a 192processor cluster using a symmetric and flat networking neighborhood. A routing schema will also be developed to maximize this network topology. This design aims to demonstrate this ne...

Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...
