Conference Paper
In this paper, we propose Threshold sensitive Energy Efficient Cluster Heads based on Maximum Energy (TEECH-ME) routing protocol for Wireless Sensor Networks (WSNs). The main objective of this technique is to improve lifetime and stability period of network by applying threshold limitations on nodes deployed in static clusters. In our propose schem...
Conference Paper
Randomly deployed nodes in wireless sensor net-work (WSN) have limited energy so their energy should be efficiently utilized. Early death of nodes is the major problem in WSN as it causes uneven load distribution. Compared with dynamic clustering schemes, multi hop communication in static clustering improves the stability region. It also provides b...

In this paper, a novel routing strategy to cater the energy consumption and delay sensitivity issues in deep underwater wireless sensor networks is proposed. This strategy is named as ESDR: Event Segregation based Delay sensitive Routing. In this strategy sensed events are segregated on the basis of their criticality and, are forwarded to their res...

Article
In this paper a review on different signal generation techniques for Radio over Fiber systems is presented. Radio over fiber has become a conspicuous contender in upcoming high data rate demands from household and enterprises users. Radio signals or waves can be generated back from optical signals at RAU so that they may be transmitted to mobile st...

The prospect of mankind returning to the Moon has garnered a great amount of attention in recent years. Dozens of lunar missions are planned for the coming decade which will require the development of a sustainable communication infrastructure with high data rates and minimal latency. Space communication systems thus far have relied on Radio Freque...

Densification and multi-band operation in 5G and beyond pose an unprecedented challenge for mobility management, particularly for inter-frequency handovers. The challenge is aggravated by the fact that the impact of key inter-frequency mobility parameters, namely A5 time to trigger (TTT), A5 threshold1 and A5 threshold2 on the system’s performance...

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...

Full-text available
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...
Article
Full-text available
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...

In this work, we analyze the impact of buffer-aided full-duplex (FD) successive relay selection schemes with energy harvesting capability of relay nodes in amplify and forward (AF) and decode and forward (DF) relaying environments for Internet of things (IoT) networks. We propose to select a relay pair based on the energy harvested and signal stren...

Full-text available
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...

Full-text available
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...
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...
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...

Question
Dear Researchers,
Greetings,
I am wondering how to deal with the following situation.
Let we have two independent and identically (e.g. exponential) distributed random variables X and Y with given PDF and CDF. I fully understand how to find the PDF and CDF of min(X,Y) or max(X,Y). However, if we define another random variable Z=X.Y. How to find the PDF and CDF of min(Z,X) or min(Z,Y).
Using the following link,
I have managed to get the close form expression for the PDF of Z given in the attached image (assuming X_1 and X_2 instead of X and Y ).
Many thanks in anticipation.
