A Cross-Layer Framework for Association Control in Wireless Mesh Networks
(2009)
The user association mechanism specified by the IEEE 802.11 standard does not consider the channel conditions and the AP load in the association process. Employing the mechanism in its plain form in wireless mesh networks, ...
Asymptotic Laws for Joint Content Replication and Delivery in Wireless Networks
(2013)
We investigate the scalability of multihop wireless communications, a major concern in networking, for the case that users access content replicated across the nodes. In contrast to the standard paradigm of randomly selected ...
A software framework for alleviating the effects of MAC-aware jamming attacks in wireless access networks
(2011)
The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...
Dynamic network provisioning for time-varying traffic
(2007)
In this paper, we address the question of dynamic network provisioning for time-varying traffic rates, with the objective of maximizing the system throughput. We assume that the network is capable of providing bandwidth ...
Trust-based exchange of services to motivate cooperation in P2P networks
(2011)
In this paper we propose a trust-based exchange framework to motivate cooperation among peers of different consumption, contribution and service evaluation profiles. Our framework consists of distributed resource allocation ...
Adaptive channel allocation in OFDM/SDMA wireless LANs with limited transceiver resources
(2004)
Smart antennas increase capacity of wireless systems by allowing channel reuse by several users in the same cell through space division multiple access (SDMA). Orthogonal Frequency Division Multiplexing (OFDM) creates ...
Multiuser Broadcast Erasure Channel With Feedback-Capacity and Algorithms
(2013)
We consider the N-user broadcast erasure channel with unicast sessions (one for each user) where receiver feedback is regularly sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ...
Exploiting wireless channel, state information for throughput maximization
(2004)
We consider the problem of scheduling packets over channels with time-varying quality. This problem has received a lot of attention lately in the context of devising methods for providing quality of service in wireless ...
Capacity and Stable Throughput Regions for the Broadcast Erasure Channel With Feedback: An Unusual Union
(2013)
We consider a source node broadcasting to two receivers over a general erasure channel with receiver feedback. We characterize the capacity region of the channel and construct algorithms based on linear network coding ...
