In this paper, we investigate the outage performance of multi-node relay network under equal power allocation (EPA) scheme. Due to the mobility of relay nodes, we proposed to design a method that considers random relay location based on random model. We conduct deep experiments which demonstrate that there exists optimal relay location to minimize the outage probability of multi-node relay netw...

—In this paper the outage-optimal relay deployment problem for amplify-and-forward (AF) multi-input multi-output (MIMO) two-way relaying network with antenna selection is studied. By utilizing an approximation of the outage probability, the outage-optimal relay location is shown feasible. On this basis a relay deployment scheme is developed by providing the near-optimal relay position in an ap...

In this article are presented the basic principles of the numerical protections used for protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a numerical distance protection DIPA 100, for a high-voltage line (an example from practice). For the numerical relay, is shown the protection characteristic of DIPA 100, characteristics of operation to faults ‘phase-p...

Buffer-aided (BA) relaying improves the diversity of cooperative networks often at cost increasing end-to-end packet delays. This characteristic renders BA unsuitable for delay-sensitive applications. However, increased makes appealing ultra-reliable communications. Towards enabling low-latency communication (URLLC), we aim enhancing supporting In this paper, reliable full-duplex (FD) network o...

In this paper, a Dual Channel Allocation (DCA) Scheme for UWB (Ultra Wide Band) with D-MAC (Distributed Medium Access Control) is proposed. Since distributed characteristic of the WiMedia DMAC supporting DRP (Distributed Reservation Protocol) scheme may cause lots of conflicts, overall performances of the WiMedia D-MAC can be deteriorated. Such DRP termination and renegotiation time delays due ...

A new tool for selecting the right pairing between inputs and outputs in a multiloop system is introduced. Similar in structure to the classical RGA the new array, called a Relative Omega Array, is based on the characteristic frequencies in open and closed loop under perfect control, as eventually detected by a classical relay test. This way the dynamic properties of the system are simply taken...

In this paper, we propose a ooding method, called Switch-Aided Flooding (SAF), for use in ATM networks. SAF-based protocols take advantage of hardware-supported cell relay and cell duplication, characteristic of such networks, in order to reduce the time needed to disseminate changes in network topology and resource availability. SAF protocols use a spanning multipoint connection (SMC), which i...

One of the main features of IEEE 802.16m is the relay transmission which could not only extend the service coverage, but also improve the quality-of-service (QoS) to the mobile stations. In this paper, we consider the cooperation among relay stations and mobile stations to improve the performance of relay transmission in IEEE 802.16m network. In this case, the relay stations and mobile stations...

This paper presents an optimal solution for amplify-and-forward (AF) single-input multiple-output (SIMO) and multiple-input single-output (MISO) wireless distributed relay networks. The optimal solutions are determined based on minimum mean square error (MMSE) criterion for optimum nondiagonal and diagonal relay amplifying matrices under the transmit power constraints at the relays. The bit err...
