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 ...
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 ...
Optimal deployment of large wireless sensor networks
(2006)
A spatially distributed set of sources is creating data that must be delivered to a spatially distributed set of sinks. A network of wireless nodes is responsible for sensing the data at the sources, transporting them over ...
Optimal overload response in sensor networks
(2006)
A single commodity network that models the information flow in an arbitrary topology sensor field that collects and forwards information to a backbone through certain designated gateway nodes is considered. Resilient ...
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. ...
