This paper presents impacts of the characteristics of Metal Oxide Varistors (MOV) for selecting and calculating the suited amount of MOVs to enable semiconductors to act as DC-Breakers. The specific structure of zinc oxide shows dependencies in its voltage and current characteristics which exhibits a hysteresis.
A major challenge for data transmission in wireless multihop networks is to efficiently utilize the present channel capacity provided by the variety of links within the network. To achieve this, we combine the concept of opportunistic routing with rateless coding and Orthogonal Frequency Division Multiple Access (OFDMA). Opportunistic routing exploits the broadcast nature of wireless transmissions...
Conventional shortest path routing protocols suffer from short link lifetime and require much effort for route recovery. Corridor-based routing aims at providing a stable support structure for wireless multihop networks, thus enabling high data throughput. The intermediate hops within the corridor contain multiple nodes, which cooperate and forward data jointly to exploit the diversity of links within...
In this paper, a pilot transmission scheme and a robust self-interference aware relay transceive filter for multipair two-way relaying are introduced. The bidirectional pairwise communications of multiple single-antenna nodes are simultaneously performed via an intermediate non-regenerative multi-antenna relay station and a pilot transmission scheme is proposed to obtain channel state information...
