In this work, a generalized approach is proposed to review the performance of relaying designs with energy harvesting capability. The unified modeling of generalized energy harvesting relaying (GEHR) design covers the non-energy harvesting designs and the well-known energy harvesting designs, i.e., time-based relaying (TR) and power-based relaying...

In this paper, we propose innovative schemes for relay selection that jointly explore packet selection and relay selection for buffer-aided amplify and forward (AF) cooperative relaying networks. The first proposed scheme chooses the most suitable channel based on link quality from all active channels, i.e., channels with neither empty nor full cor...

In this paper, a novel design of an incremental cooperative communication with downlink non-orthogonal multiple access is studied and analyzed for a buffer-aided cooperative relay network. The phenomenon of packet diversity is taken into consideration instead of link diversity to overcome the lousy channels. A source multi-casts data packets in the...
Conference Paper
Full-text available
Despite significant performance gains, buffer-aided cooperative communication incurs an increased latency. It is generally handled by prioritizing relay-to-destination link selection. The contribution of this paper is twofold , firstly, we study the buffer threshold based buffer-aided relay selection scheme in Nakagami-m fading channels with non-ho...
Conference Paper
Full-text available
Buffer-aided cooperative relaying is often investigated either using decode and forward (DF) or amplify and forward (AF) relaying rules. However, it is seldom investigated using the hybrid decode-amplify-forward (HDAF) relaying rule. In this work, the performance of signal-to-noise ratio (SNR) based HDAF relaying rule is followed for buffer-aided c...
Thesis
In this thesis, a suite of schemes is presented to enhance the performance of cooperative communication networks. In particular, techniques to improve the outage probability, end-to-end delay and throughput performances are presented. Firstly, a buffer-aided cooperative communication is studied and analyzed for packet selection and relay selection....

Buffer-equipped relay selection schemes in cooperative communication offer evident performance gains in terms of the outage probability and throughput. However, it brings in the increased delay which can be reduced by increasing the selection probability of relay-to-destination (RD) links. In this work, a controlling parameter, termed as the buffer...

This paper investigates the performance of a bufferaided IoT based cooperative relay network. In the proposed design, each location in a buffer is assumed to act independently called the virtual relay having a buffer of size 1. The relay selection is based on instantaneous strength of the wireless link and status of the virtual relay buffer. The pr...
Article
The requirement of high data rates, low latency, efficient use of spectrum and coexistence of different network technologies are major considerations in Internet of Things (IoT) based Fifth Generation (5G) networks. To achieve the above requirements, the incorporation of Artificial Intelligence (AI) is required to make efficient decisions based on...
Conference Paper
This paper presents a decisive threshold termed as the buffer-threshold to control the selection probability of source-relay (SR) or relay-destination (RD) links for the buffer aided cooperative wireless networks. The weights of the links are reassigned using buffer-threshold and a link with the maximum weight is activated. The proposed scheme is t...
Conference Paper
This piece of work presents a novel design for buffer-aided relaying to increase the diversity gain. In this design, we used random buffer access method and associate each buffer location with its own antenna resource. Thus, each buffer location acts as an independent entity known as the virtual relay. The relay selection is based on the instantane...
Conference Paper
This paper explored cooperative relaying in the presence of energy constrained relays with data storage facility. The relays depend only on the source signal to harvest energy and forward signal to the destination. The relay is selected according to the instantaneous strength of the wireless link. The strongest link among all links on both sides i....
Article
In this letter, we discuss multiple links with equal weights, in buffer size based relay selection schemes in cooperative wireless networks. A general relay selection factor is defined, which includes the weight of the link as the first metric and the link quality, or priority, as the second metric for different cases of the same weight. The Markov...

This paper presents an incremental cooperative communication scheme for a buffer-aided three node relay network consisting of a source, an Amplify and Forward (AF) relay and a destination. We consider the presence of direct link and propose a scheme which is based on the concept of packet diversity rather than link diversity. The scheme is designed...
Conference Paper
Relay selection in cooperative communication is an efficient approach to mitigate the spectral efficiency loss faced in cooperative diversity systems. In this paper, we propose a relay selection scheme for buffer-aided cooperative systems. It simultaneously considers the instantaneous link quality and the buffer status of relay nodes in the relay s...
Research Proposal

This work investigates a buffer-aided cooperative communication system in wireless networks. In this regard, we intend to propose a suite of schemes for a buffer-aided cooperative communication network comprising of a source, a destination and a relay or a set of relays. Our objective is to minimize the outage probability, minimize the delay and im...

Impairments of the acoustic channel impose the requirement of improvement in throughput efficiency of the network. Therefore, efficient mechanisms must be proposed to increase throughput while conserving energy at the same time. In this paper, we propose two energy efficient geographic opportunistic routing protocols for underwater wireless sensor...

Conference Paper
Underwater Sensor Networks (UWSN) has recently become an important field due to the importance of underwater exploration. The unique characteristics of underwater environment make the designing of routing protocol a challenging task. It is difficult to replace the batteries, therefore, it is very important to design a routing protocol that gives ma...

Mission critical applications impose the require-ments of reliability and network efficiency on Underwater Wire-less Sensor Networks (UWSN). Innovative routing solutions are therefore required for efficient data forwarding. In this paper, we propose a cooperative routing scheme for UWSNs to enhance network performance. Many cooperative communicatio...

Reliability is key factor for mission critical data applications. In poor underwater environment, where fading and noises are unavoidable, it is very difficult to have error free data transmission. This paper presents a novel cooperative routing protocol for Underwater Wireless Sensor Networks (UWSN) called Adaptive Cooperation in Energy Efficient...

I have started the work broadly on buffer aided cooperative communication couple of moths ago. I found the relay selection quite interesting. I have studied max-min, max-max, max-link, and your work on buffer state based relay selection.
