In multi-hop wireless networks, the way the network topology is defined has a strong impact on routing. This paper deals with topology control in cellular networks with relays. Several topology control algorithms taken from ad-hoc networks are adapted to cellular networks. Most of the algorithms considered here are based on proximity graphs. Performance analysis is carried out in a realistic scenario...
This paper studies the problem of topology control in random wireless ad-hoc networks through power assignment for n nodes uniformly distributed in a unit square. In particular, we are interested in asymmetric power assignments so that the induced communication graph has a good distance and energy stretch simultaneously, with additional optimization objectives: both minimizing the total energy consumption,...
We consider the question of obtaining tight delay guarantees for throughout-optimal link scheduling in arbitrary topology wireless ad-hoc networks. We consider two classes of scheduling policies: 1) a maximum queue-length weighted independent set scheduling policy, and 2) a randomized independent set scheduling policy where the independent set scheduling probabilities are selected optimally. Both...
Topology control in wireless ad hoc networks can be considered the task of given a network connectivity graph computing a sub graph with specific desired properties, such as connectivity, symmetry, sparsity, low interference. All previous approaches used for topology control have in common that they model wireless networks as purely geometric graphs, hence neglecting one of the most crucial aspects...
Topology control is the task of establishing an efficient underlying graph for ad-hoc networks over which high level routing protocols are implemented. The following design goals are of fundamental importance for wireless topologies: (1) low level of interference; (2) minimum energy consumption; (3) high spatial reuse; (4) connectivity; (5) planarity; (6) sparseness; (7) symmetry; (8) small nodal...
