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 ...
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 ...
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 ...
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 ...
Fast neighbor positioning and medium access in wireless networks with directional antennas
(2013)
We study the problem of fast neighbor positioning and medium access in wireless networks with directional antennas. In this problem, the cross-layer dimension inherently comes into stage through the impact of PHY-layer ...
Joint Time-Domain Resource Partitioning, Rate Allocation, and Video Quality Adaptation in Heterogeneous Cellular Networks
(2015)
Heterogenous cellular networks (HCN) introduce small cells within the transmission range of a macrocell. For the efficient operation of HCNs it is essential that the high-power macrocell shuts off its transmissions for an ...
Interconnection of geographically distributed wireless mesh testbeds: Resource sharing on a large scale
(2011)
Creating large scale testbeds for evaluating wireless mesh technologies and protocols, and for testing their ability to support real world applications in realistic environments, is a crucial step towards the ultimate ...
High performance, low complexity cooperative caching for wireless sensor networks
(2011)
During the last decade, Wireless Sensor Networks have emerged and matured at such point that they currently support several applications such as environment control, intelligent buildings, target tracking in battlefields. ...
