Relay networks have usually been investigated within a single source (S), relay (R), and destination (D) group in the literature. In this work, cooperative diversity techniques will be investigated for relay networks having multiple S, R and D's. Simulations results for linear and uniform S, R and D localizations will be presented.

Relay Selection for Efficient HARQ-IR Protocols in Relay-Assisted Multisource Multicast Networks Quoc-Tuan Vien, Quoc-Tuan Vien; Nguyen, Huan X.; Shah, Purav; Ever, Enver; Duc To, Duc To (2014-05-21) This paper investigates relay selection for reliable data transmission in relay-assisted multisource multicast networks (RMMNs) where multiple source nodes distribute information to a set of destination nodes with the assistance of multiple relay nodes. Hybrid automatic repeat request with incremental redundancy (HARQ-IR) is used and supported by either a physical-layer network coding (PNC) or an analog network coding (ANC) technique employed at the relays. By deriving efficiency metrics of the HARQ-IR prot...
Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29) In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Relay-Assisted Beamforming for Multicast Systems with Energy Harvesting Capability Demir, Özlem Tuğfe; Tuncer, Temel Engin (2016-05-19) In this paper, multi-group multicasting scenario is considered where single antenna sources transmit their own information to different groups of users with the help of single antenna relays. Users have energy harvesting capability, i.e., a part of the received signal is used for information decoding while the rest is used for energy harvesting. Beamforming is performed by the relays which use amplify-and-forward protocol. The design of complex relay coefficients and power splitting ratios for the users is ...
DISTRIBUTED BEAMFORMING IN RELAY NETWORKS FOR ENERGY HARVESTING MULTI-GROUP MULTICAST SYSTEMS Demir, Özlem Tuğfe; Tuncer, Temel Engin (2016-03-25) In this paper, simultaneous wireless information and power transfer (SWIPT) is considered for multi-group multicasting relay networks where there is no direct link between the source and destination nodes. Each source transmits its own multicast stream to a group of users with the help of single antenna relays which use amplify-and-forward relay protocol. Each user has energy harvesting capability. A part of the received signal is used for information decoding while the rest is used for energy harvesting. T...
Path planning and localization for mobile anchor based wireless sensor networks Erdemir, Ecenaz; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2017) In wireless sensor networks, sensors with limited resources are distributed in a wide area. Localizing the sensors is an important problem. Anchor nodes with known positions are used for sensor localization. A simple and efficient way of generating anchor nodes is to use mobile anchors which have built-in GPS units. In this thesis, a single mobile anchor is used to traverse the region of interest to communicate with the sensor nodes and identify their positions. Therefore planning the best trajectory for th...
