The low-power communication in wireless sensor networks can be impacted by severe channel impairments. In this paper, to address this problem and achieve high network goodput, we propose that the medium access control protocol takes into consideration the ...
In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...
The main objectives pursued by parallelism in communications are network capacity enhancement and fault-tolerance. Efficiently enhancing the capacity of a network by parallel communications is a non-trivial task. Some applications may also allow one to spl ...
Slowing down light to produce optical delay lines for communication networks has advanced enormously in the last year. Luc Thévenaz and Miguel Gonzalez-Herraez chart this recent progress and describe the new challenges facing developers of practical device ...
The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
We consider a simple network, where a source and destination node are connected with a line of erasure channels. It is well known that in order to achieve the min-cut capacity, the intermediate nodes are required to process the information. We propose codi ...
Lattice networks are widely used in regular settings like grid computing, distributed control, satellite constellations, and sensor networks. Thus, limits on capacity, optimal routing policies, and performance with finite buffers are key issues and are add ...
We develop three functions around the MAC layer: (1) Pseudo broadcast is a technique used to improve throughput of broadcast transmissions in case of congested networks. The mechanism consists in sending a packet in unicast to a station using RTS/CTS. Othe ...
Packet detection and timing acquisition for IR-UWB networks such as 802.15.4a relies on the presence of an acquisition sequence (or preamble) at the beginning of each packet. A simple network design choice is to use a common acquisition sequence for the wh ...
