Unmanned air vehicles (UAVs) can improve better network performance for ground-based wireless MANETs (mobile ad hoc networks). In this paper, we consider a typical scenario of a MANET with a UAV as the relay node and ground nodes can both connect with the UAV and other ground nodes. We study how to improve the network connectivity and network throughput of the network. By formulating the mobility...
Understanding of the macroscopic routing behavior of the inter-domain routing system remains a difficult challenge because the inter-domain routing is a very complex system with very large scale. In this paper, we propose a Cellular Automata (CA) model to investigate the collective routing behavior of the inter-domain routing system. We believe CA model can allow us to better understand the macroscopic...
Information gathering is one of typical applications in wireless sensor networks, where energy-constrained sensors are densely deployed to collect environmental information and transmit data to a base station for further processing. Sensors directly transmit data to a far away base station may quickly drain their batteries and greatly shorten the network lifetime. Partitioning network into several...
The collective dynamics of large-scale computer networks remains elusive due to not only the internal adaptive behaviors of network-wide flows, but also the spatial–temporal changes in the external environment. In this paper, we investigate the time-dependent collective behavior by using a computer network model, recently developed to study space–time characteristics of congestion in large networks...
