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 protocols, we propose relay selection schemes for RMMNs to minimize the transmission delay and energy consumption. Simulation results are provided to analyse each relay selection scheme.


Cooperative Network Coded ARQ Strategy for Broadcast Networks
Tutgun, Rasit; AKTAŞ, EMRE (2015-06-12)
A novel cooperative automatic repeat request (ARQ) method with network coding is proposed for broadcast networks where single source node broadcasts multiple packets to multiple destinations. Upon a failed transmission, multiple relays cooperate with the source node at the retransmission phase, where network coding is used to combine multiple lost packets. A random access mechanism is employed where retransmission is done according to back-off counters. The proposed method employs the back-off mechanism to ...

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...
Routing Algorithms As An Application Of Graph Theory
Yıldırım, Gökberk; Özbudak, Ferruh; Department of Cryptography (2023-1-27)
This paper examines routing algorithms that are generally used in various network types, such as Internet Protocol in graph-based models, to find the shortest routing path or minimum cost. The fundamental approach for calculating the shortest path between one point to another is searching a given graph, starting at the source node, and traversing adjacent nodes until the destination node is reached. The aim is to identify the shortest routing path to the destination node. This paper searches well-known rout...
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...
Cooperative Multiple-Access in Fading Relay Channels
Yılmaz, Ayşen (2006-06-15)
Virtual antenna arrays can be constructed via relaying even in the case that there is insufficient physical space or other resources for multiple antennae on wireless nodes. When there is a multiple access scenario, relaying offers a variety of ways to establish communication between source and destination nodes. We will compare a scheme based on space division multiple access to previously studied time division based ones. We observe that space division improves especially the ergodic capacity.
