Power-Controlled Directional Medium Access Control for Wireless Mesh Networks such networks many approaches have been proposed, including directional and adaptive antennas. However, while adaptive antennas can improve the utilization of the wireless medium by reducing radio interference and the impact of the exposed nodes problem, they can also exacerbate the hidden nodes pr

FID

Subnet Formation and Address Allocation Approach for a Routing with Subnets Scheme in MANETsstructure in MANETs. We show scenarios in which a MANET with subnet structure is applicable, present the main technical challenges for the application of this structure and show that a reduction of routing overhead from a factor of N. to N./k (being N the number of nodes and k the number of subnets)

The State of the Art in Cross-Layer Design for Wireless Sensor Networksy is proposed. The communication protocols devised for WSNs that focus on cross-layer design techniques are reviewed and classified, based on the network layers they aim at replacing in the classical open system interconnection (OSI) network stack. Furthermore, systematic methodologies for the desig

A Low Computation Cost Algorithm to Solve Cellular Systems with Retrials Accuratelyising in mobile cellular networks. We limit the number of levels that define the system by aggregating all levels beyond a given one in order to manage curse of dimensionality issue. The developed methodology allows to balance accuracy and computational cost. We determine the relative error of diffe

Hierarchical Admission Control in Mobile Cellular Networks Using Adaptive Bandwidth Reservationolicy. The scheme adjusts the MGC configuration parameters by continuously tracking the Quality of Service (QoS) perceived by users, adapting to any mix of aggregated traffic and enforcing a differentiated treatment among services during underload and overload episodes. We compare our adaptive schem
