Query: Cross Layer Design for Maximizing Network Utility in Multiple Gateways
  Wireless Mesh Networks   We investigate the problem of network utility maximization in multiple
gateways wireless mesh networks by considering Signal to Interference plus
Noise Ratio (SINR) as the interference model. The aim is a cross layer design
that considers joint rate control, traffic splitting, routing, scheduling, link
rate allocation and power control to formulate the network utility maximization
problem. As this problem is computationally complex, we propose the Joint
dynamic Gateway selection, link Rate allocation and Power control (JGRP)
algorithm based on the differential backlog as a sub-optimal solution. This
algorithm first constructs the initial network topology, and then in each time
slot, determines the generation rate and destination gateway of each traffic
flow, simultaneously. The other main task of this algorithm is joint routing,
scheduling, links rate allocation and node power allocation in each time slot.
Moreover, for improving the fairness, we propose some new parameters instead of
the differential backlog in JGRP algorithm. Simulation results show that using
the proposed parameters in JGRP algorithm improves fairness from throughput and
delay point of views.
