This paper is on relay selection in uplink of an in-band full-duplex (IBFD) cooperative cellular network. Assuming an orthogonal frequency division multiple access (OFDMA) cellular network, we develop a relay selection and resource allocation algorithm for this network. The relay selection algorithms select the best relay based on distance between users and signal to interference plus noise rat...

Relay stations are usually used to enhance the signal strength for the users near cell boundary, thereby extending the cell coverage. However, transmission through a relay station needs two transmission phases. The first phase is from base station to relay station, and the second one is from relay station to mobile station. Thus, using relay station may decrease system capacity due to two-phase...

This paper focuses on a joint relay-selection and resource-allocation algorithm for an Amplify-andForward (AF) cooperative network. In a multiuser scenario, joint relay selection and power allocation is a combinational problem for heterogeneous, i.e., real time (RT) and non-real time (NRT), users. In single relay AF (S-AF) scheme, a source-destination pair selects best relay. Thus only two chan...

In this study, the authours present a low-complexity relay selection scheme for channel-state information (CSI)-assisted dual-hop amplify-and-forward cooperative systems. The scheme is mainly based on the switch-and-examine diversity combining (SEC) and SEC post-selection (SECps) techniques in which a relay out of multiple relays is selected to forward the source signal to destination. The sele...

The focus of this paper is cross layer optimization of relay selection on multihop wireless ad hoc networks. Cross-layer metrics that will be optimized are power consumption, throughput, and load balancing in wireless ad hoc networks for the outdoor and indoor configurations. Those three resources (performance indicators) are optimized using the multi objective optimization with Pareto method. ...

Cooperative relaying is one of the promising technology which is used to improve coverage and spatial diversity. A new relay strategy, the N Best-Relay Selection scheme is proposed to improve the bandwidth penalty and to increase the spatial diversity by using a sub-optimal allocation for the relay relative distance between the source and destination in a multi-hop cooperative systems. A single...

In deterministic networks where relay nodes are stationary, combined selection is an efficient scheme, which capable of achieving the near-optimal outage performance with much lower system complexity. However, efficiency only validated upon fixed topological settings. To investigate in spatially random (SRNs), we employ Poisson point process to model dynamical nature cooperative and study propo...

The outage probability of dual-hop links with partial relay selection over Rayleigh fading channel in the presence of interferences is analysed. The outage expressions for amplify-and-forward (AF) and decode-and-forward (DF) relaying with relay selection, based on the instantaneous signal-to-interference ratio (SIR), are derived. Numerical results for both types of relays are presented and comp...

—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...
