Distributed space-time coding of over-the-air superimposed packets in wireless networks
(2013)In this paper we propose a new cooperative packet transmission scheme that allows independent sources to superimpose over-the-air their packet transmissions. Relay nodes are used and cooperative diversity is combined with ... -
End-to-end bandwidth guarantees through fair local spectrum share in wireless ad-hoc networks
(2003)Sharing the locally common spectrum among the links of the same vicinity is a fundamental problem in wire-less ad-hoc networks. Lately some scheduling approaches have been proposed that guarantee fair share of the bandwidth ... -
Energy-aware joint power, packet and topology optimization by simulated annealing for WSNs
(2013)Energy-aware connectivity in wireless sensor networks (WSNs) can increase their network lifetime. This can be achieved by optimizing the power control, a particular communication mechanism and the topology control. To this ... -
Handling asymmetry in gain in directional antenna equipped ad hoc networks
(2005)The deployment of traditional higher layer protocols (especially the IEEE 802.11 MAC protocol at the MAC layer) with directional antennae could lead to problems from an increased number of collisions; this effect is primarily ... -
Layered backpressure scheduling for delay reduction in ad hoc networks
(2011)Packet scheduling in wireless ad hoc networks is a fundamental problem for ad hoc networking. Backpressure scheduling is a solid and throughput optimal policy for such networks, but suffers from increased delays. In this ... -
Memory management for receive-side enhancement of continuous media QoS
(2005)Layering and conventional packet buffering in user-level continuous media receivers can increase end-to-end delay and packet loss. These QoS metrics and delay jitter can also deteriorate when general-purpose memory allocators ... -
On emulating hardware/software co-designed control algorithms for packet switches
(2014)Hardware accelerators in networking systems for control algorithms offer a promising approach to scale performance. To that end, several research efforts have been devoted to verify a hardware version of complex control ... -
On optimal cooperative route caching in large, memory-limited wireless ad hoc networks
(2004)Caching is a popular mechanism for enhancing performance in various layers and applications of computer networking. We introduce both a model and algorithms for caching routing information in large, memory-limited wireless ... -
Query sensitive storage for wireless sensor networks
(2009)Storage management in wireless sensor networks is an area that has started to attract significant attention, and several methods have been proposed, such as Local Storage (LS), Data-Centric Storage (DCS) and more recently ... -
Stochastic comparisons for a static routing problem with resequencing
(2004)In communication networks, packets from the same source-destination pair may be routed along several paths and arrive at their receiver out of order. This often necessitates the use of a resequencing buffer at the destination. ...
