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 ...
CDR-MAC: A protocol for full exploitation of directional antennas in ad hoc wireless networks
(2008)
In this paper, we propose a new Medium Access Control (MAC) protocol for full exploitation of directional antennas in wireless networks. The protocol introduces a circular directional transmission of the Request To Send ...
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. ...
Dynamic resource allocation in CDMA systems with deterministic codes and multirate provisioning
(2006)
Next generation wireless CDMA systems will provide high and variable data rates by using multicode structures, controllable code spreading gains, and transmit power adaptation. We address the emerging resource allocation ...
