TopoObfu:A Network Topology Obfuscation Mechanism to Defense Network Reconnaissance [PDF]

Jisuanji kexue, 2021
Some typical network attacks,such as link-flooding attack,need to be carried out on critical links based on topology reconnaissance,which has strong destructiveness and stealthiness.In order to defense these attacks effectively,TopoObfu,a topology ...

The Minimum Scheduling Time for Convergecast in Wireless Sensor Networks

Algorithms, 2014
We study the scheduling problem for data collection from sensor nodes to the sink node in wireless sensor networks, also referred to as the convergecast problem. The convergecast problem in general network topology has been proven to be NP-hard.

Distributed Energy-Efficient Topology Control Algorithm in Home M2M Networks

International Journal of Distributed Sensor Networks, 2012
Because machine-to-machine (M2M) technology enables machines to communicate with each other without human intervention, it could play a big role in sensor network systems.

Evolution of cooperation on dynamical graphs [PDF]

, 2009
There are two key characteristic of animal and human societies: (1) degree heterogeneity, meaning that not all individual have the same number of associates; and (2) the interaction topology is not static, i.e.

Intuitive network topology

Journal of Experimental Psychology: General
Topology is the branch of mathematics that seeks to understand and describe spatial relations. A number of studies have examined the human perception of topology — in particular, whether adults and young children perceive and differentiate objects based on features like closure, boundedness, and emptiness. Topology is about more than ‘wholes and holes’,
