The increasing need of protocol development environments and network performance evaluation tools gives rise to the research of flexible, scalable, and accurate network emulators. The desired network emulator should be able to facilitate the emulation of either wireline or wireless networks. In the case when network topology is critical to the underlying network protocol, the emulator should pr...

his survey focuses on measurements of the network topology, i.e., the representation of the interconnection between directly connected peers in the network. While some of this information can be gleaned from passive measurements, researchers largely obtain the topology and its characteristics from active measurements. There are three different levels at which to describe the network topology: t...

Wireless Sensor Networks are highly distributed self organized systems. WSN have been deployed in various fields. Now a day, Topology issues have received more and more attentions in Wireless Sensor Networks (WSN). While WSN applications are normally optimized by the given underlying network topology, another trend is to optimize WSN by means of topology control. In this area, a number of appro...

In now multi-agent systems, the underlying networks are always dynamic and the network topologies are always changed in the operation. Therefore, the coordination of agents shall be adjusted for the dynamic network topology. Aiming at the dynamics of underlying network topology, a novel adaptive multi-agents coordination model is explored in this paper. In the paper, a series of algorithms for ...

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...

It is of great significance to manage and maintain EPON (Ethernet Passive Optical Network) effectively by discovering devices running in EPON network and relationships between devices automatically. After analyzing the characteristics of EPON network and basic principle of topology discovery, a topology discovery scheme is proposed, which is designed and implemented based on WebNMS framework to...

In order to achieve optimization control of complex network topology connection and to identify the network topology which with the greatest network connection gain, this paper proposes the network topology connection optimization control algorithm based on network efficiency and average connectivity. The algorithm uses network efficiency to characterize network connectivity gains, uses average...

Ad hoc mobile networks have dynamic topology with no central management. Because of the high mobility of nodes, the network topology may change constantly, so creating a routing with high reliability is one of the major challenges of these networks .In the proposed framework first, by finding directions to the destination and calculating the value of the rout the combination of this value with ...
