Various sensor network studies have reported instances of faults in WSN. This paper focuses specifically on two types of faults, those caused by sensor node crashes resulting from power depletion or unreliable hardware and those caused by unpredictable link connectivity due to unstable wireless links. Intellectus [31] addresses these faults through the use(More)
Within a wireless sensor networks (WSN), network topology and connectivity is one of the key elements that need to be known in order to perform fault and isolation detection. Many of the faults observed in real WSN (link change, nodes switched off and reboot), create dynamic topology; it is important to understand the occurrence of such dynamic changes(More)
Within wireless sensor networks (WSN), network topology and connectivity is one of the key elements that needs to be known in order to perform fault detection and isolation identification. Knowledge of connectivity is fundamental to understanding the operation of a given sensor network. The Intellect us methodology described herein can be used to monitor(More)
A central challenge facing sensor network research and development is the difficulty in providing effective autonomous management capability. This is due to a large number of control parameters, unexpected changes of the network topology, and dynamic application requirements. Network management is also a challenging task for the remote user due to the(More)
The low molecular weight iron found in the guinea pig reticulocyte has been partially characterized. On thin layer chromatography it is distinguishable from the iron complexes of a variety of nucleotides, sugars, and amino acids. On paper chromatography it comigrates with a 250-nm absorbing, orcinol-positive material. The eluted count peak contains(More)
The ligands that bind iron and heme in reticulocyte and may regulate their distribution are not known. Guinea pig reticulocyte hemolysates were labeled with 59Fe and filtered through molecular weight sieving columns. 59Fe-containing peaks of ferritin, transferrin, and hemoglobin were identified, as well as a low molecular weight peak containing(More)
This paper describes a novel emergency communication network architecture implemented within the FP7 EU project E-SPONDER [1]. It is characterized by the deployment of heterogeneous wireless systems and also by its holistic approach achieving reliability, high performance, reconfigurability and standalone operation. It is a complete suite of real-time(More)
