Joint Channel Assignment and Routing for Throughput Optimization in Multiradio Wireless Mesh Networks
TLDR
A solution is developed that optimizes the overall network throughput subject to fairness constraints on allocation of scarce wireless capacity among mobile clients, and the performance of the algorithms is within a constant factor of that of any optimal algorithm for the joint channel assignment and routing problem.

Argos: practical many-antenna base stations
TLDR
This work presents the design, realization, and evaluation of Argos, the first reported base station architecture that is capable of serving many terminals simultaneously through MUBF with a large number of antennas (M >> 10), and reports an Argos prototype with 64 antennas and capable ofserving 15 clients simultaneously.

UCAN: a unified cellular and ad-hoc network architecture
TLDR
This paper proposes the Unified Cellular and Ad-Hoc Network (UCAN) architecture for enhancing cell throughput, while maintaining fairness, and refine the 3G base station scheduling algorithm so that the throughput gains of active clients are distributed proportional to their average channel rate. Expand
Gossip-based ad hoc routing
TLDR
Simulations show that adding gossiping to AODV results in significant performance improvement, even in networks as small as 150 nodes, and suggest that the improvement should be even more significant in larger networks. Expand
Minimum-energy mobile wireless networks revisited
We propose a protocol that, given a communication network, computes a subnetwork such that, for every pair (u, /spl upsi/) of nodes connected in the original network, there is a a minimum-energy pathExpand

Fairness and Load Balancing in Wireless LANs Using Association Control
TLDR
This paper presents an efficient solution to determine the user-AP associations for max-min fair bandwidth allocation, and shows the strong correlation between fairness and load balancing, which enables them to use load balancing techniques for obtaining optimal maximum-minFair bandwidth allocation.

SoftCell: scalable and flexible cellular core network architecture
TLDR
The presented SoftCell is a scalable architecture that supports fine-grained policies for mobile devices in cellular core networks, using commodity switches and servers, and enables operators to realize high-level service policies that direct traffic through sequences of middleboxes based on subscriber attributes and applications. Expand
SoftRAN: software defined radio access network
TLDR
This work argues that LTE's current distributed control plane is suboptimal in achieving the above objective and proposes SoftRAN, a fundamental rethink of the radio access layer that abstracts all base stations in a local geographical area as a virtual big-base station comprised of a central controller and radio elements. Expand
Analysis of a cone-based distributed topology control algorithm for wireless multi-hop networks
TLDR
It is shown that taking α = 5π/6 is a necessary and sufficient condition to guarantee that network connectivity is preserved and a set of optimizations that further reduce power consumption and prove that they retain network connectivity are proposed. Expand
