Abstract In ad hoc wireless networking, units are connected to each other rather than to a central, fixed, infrastructure. Constructing and maintaining such networks create several trade-off problems between robustness, communication speed, power consumption, etc., that bridges engineering, computer science and the physics of complex systems. In this work, we address the role of mobility patterns of the agents on the optimal tuning of a small-world type network construction method. By this… 

Food webs over time: evaluating structural differences and variability of degree distributions in food webs

Ecological networks are usually analyzed as time‐aggregated units, where time‐specific interactions are aggregated into one single network. However, the extent to which the structure of these

Heterogeneous attachment strategies optimize the topology of dynamic wireless networks

This paper investigates simple models of how agents can choose their neighbors in a dynamic set of spatially embedded agents and finds that the optimal topologies are obtained for strategies resulting in a mix of most local and a few random connections.

A survey of mobility models for ad hoc network research

A survey of mobility models that are used in the simulations of ad hoc networks and illustrates how the performance results of an ad hoc network protocol drastically change as a result of changing the mobility model simulated.

Analyzing the impact of mobility in ad hoc networks

A statistical framework is developed to distinguish between the mobility and interference or collision errors and this framework is used together with measurements to validate two commonly used stochastic mobility models including the random waypoint and the random reference group mobility model.

Human Mobility Patterns and Their Impact on Routing in Human-Driven Mobile Networks

It is demonstrated that the Levy walk model can be used to recreate the statistical patterns commonly observed in previous mobility studies such as the power-law distributions of human inter-contact times and that the simulation performance of mobile network routing protocols under the LevyWalk model exhibits distinctive performance features unexplored under existing mobility models.

This work presents a distributed topology control algorithm to calculate the per-node minimum transmission power, so that reachability between any two nodes is guaranteed to be the same as in the initial topology.

Longitudinal hopping in intervehicle communication: theory and simulations on modeled and empirical trajectory data.

The longitudinal hopping mode in which messages are transported using equipped vehicles driving in the same direction as a relay is studied and it is found that this additional stochastic component generally increased connectivity compared to a deterministic transmission with the same mean.

A multiscale quartered (MSQ) network is introduced that is stochastically constructed by recursive subdivision of polygonal faces as a self-similar tiling that has several advantages: the robustness of connectivity, the bounded short path lengths, and the shortest distance routing algorithm in a distributive manner.
