This paper explores the relay selection scheme for two-way relay channels with physical layer network coding (PNC), where two end nodes exchange information via a selected relay node with the minimal symbol error rate (SER) performance among multiple candidate relay nodes. To reduce the computational complexity, we also propose a suboptimal minimal SER-based relay selection. The end-to-end SER ...

This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to operating without knowledge codebooks, i.e., it performs processing. Moreover, due constraint, impossible for inform destination node perfect state (CSI) in each realization. To evaluate rate, we first provide upper bou...

This paper investigates adaptive streaming codes over a three-node relayed network. In this setting, source node transmits sequence of message packets to destination with help relay. The source-to-relay and relay-to-destination links are unreliable introduce at most N <sub xmlns:xlink="http://w...

The Passive sensor nodes are operated in a very low power regime i.e. -10dBm to -30dBm. Due to this fact, there is a high chance of data to be lost or severely corrupted due to overcome of noisy environment. In order to tackle this problem it was suggested that node cooperation is able to combat this. Node cooperation is very helpful in order to take the data node by node until to the final des...

In this paper, we analyze the performance of vehicle-to-vehicle (V2V) communication system, which employs full-duplex (FD) and energy harvesting (EH) techniques at source relay nodes from power beacon (PB) through radio frequency. Unlike previous systemswhere all located fixed locations, investigate case that three (source, relay,and destination) are moving vehicles. Therefore, channels between...

A Wireless Sensor Network (WSN) consists of a hundred of sensor nodes deployed in sensing fields in order to serve various applications. The limited resources of sensor nodes such as energy source, computational ability and communication bandwidth are the most important challenges in designing a reliable smart WSN which guarantees the connectivity and maximizes the lifetime of sensor’s batterie...

The development of Internet Things devices as well the increase nodes in wireless networks, motivates use node?s cooperation for system performance improvement. On other hand, power requirements increasing number leads to need new powering sources. In this paper we consider device-to-device relay-assisted system, where decode-and-forward relay is not equipped with its own supply, but it harvest...

Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attent...

Relay selection is an effective method to realize the cooperative diversity gain in wireless networks. In this paper, we study a threshold-based single relay selection algorithm. A reasonable threshold value is set at each relay node, and the first relay with the instantaneous channel gain larger than the threshold will be selected to cooperate with the source. The exact and closed form express...

To expand the operative area for surveillance UAV, we propose the use of a relay UAV. The relay UAV is used as an intermediary node in a communication network: the surveillance UAV transmits data to the relay UAV, which sends it back to a ground station. In this exploratory report, we calculate the route for a relay UAV, to ensure communication at certain time points, given the route of the sur...
