Efficient Topology Control for Ad-Hoc Wireless Networks with Non-Uniform Transmission Ranges
Wireless network topology control has drawn considerable attentions recently. However, priori arts assumed that the wireless ad hoc networks are modeled by unit disk graphs (UDG), i.e., two mobile hosts can communicate as long as their Euclidean distance is no more than a threshold. However, practically, the networks are never so perfect as unit disk graphs: the transmission ranges may vary due...

Wireless network topology control has drawn considerable attention recently. Priori arts assumed that the wireless ad hoc networks are modeled by unit disk graphs (UDG), i.e., two mobile hosts can communicate as long as their Euclidean distance is no more than a threshold.

متن کاملEnergy-Efficient Topology Control for Wireless Ad Hoc Sensor Networks
Energy-saving is a critical issue in mobile computing. Given a set of hosts which forms a wireless ad hoc network and an initial energy for each host, this paper considers the topology control problem by tuning the transmission powers of hosts to control the structure of the network. The target topology includes 1-edge-, 1-vertex-, 2-edge-, and 2-vertex-connected graphs. The goal is to maximize...
متن کاملDynamic Energy Efficient Topology for Wireless Ad hoc Sensor Networks
Wireless Sensor Ad hoc Networks (WASNs) are self organizing, self-configuring and multi-hop wireless networks, in which each node communicates with other nodes directly or indirectly through intermediate nodes without any infrastructure. Besides these characteristics challenges like limited energy, dynamic topology, low bandwidth and security exists. The arrangement of nodes in WASN is called t...
متن کاملWireless Ad Hoc Networks with Tunable Topology
We study the set of connectivity and topological properties achievable by heterogeneous Wireless Ad Hoc Networks (WANETs). Instead of using the well known Random Geometric Graph (RGG) model, which is more suitable for homogeneous WANETs, we use Geographical Threshold Graphs (GTGs) to model WANETs with tunable topology. The GTG model allows nodes to have different capabilities, e.g., power and b...
