But the main idea behind this article was to assess the impact of whether SNS addiction effects online self-disclosure or not moreover its mediation impact. The main idea of this study is to investigate the mediating effect of habit, psychological wellbeing, psychological dependence and perceived ease of use between SNS and self-disclosure. Specifically, this research proposes a model to examine how the effect of SNS usage mediates self-disclosure through psychological conditions. Data was collected online using the Google documents application, from university students in Pakistan. In total 338 entries were analyzed and reported, for analysis SPSS version 21 was used. Results show that Pakistani youth tend to have higher selfdisclosure online due to habit, perceived ease of use and while sharing online makes them feel better as the mediator of psychological well-being also reported a positive mediating effect.

This network node is power limited. However, the routing mechanism should be improved which extend the lifetime and performance of UAV nodes. This manuscript intends to introduce a concept of a cross-layer method for efficient power and routing for UAVCN to increase communication performance. The cross-layer methodology integrates the physical, link and network layer. An efficient power optimized link state routing (EP-OLSR) protocol is proposed which is an extension to optimized link state routing (OLSR) protocol. The proposed routing protocol evaluated by developing scenarios of UAVCN in OPNET modeler 14.5. The simulation is carried out by implementing OLSR and EP-OLSR using different network parameters and compared the routing protocols performance. The results showed that the EP-OLSR maximizes network performance efficiency as compared to OLSR. It minimizes the delay and maximizes the throughput and increases the network performance.

FSO is a line of sight communication which is used to convey data from an optical transmitter to an optical receiver through atmosphere. FSO offers higher data rates but fading level due to atmospheric effects (like sand, dust, fog, rain, snow etc.) are higher than RF (radio frequency) technology. The atmosphere affects the laser beam passing through it. The atmospheric turbulence and scattering results in the degradation of the signal. In this research paper is focused and analyzes the variations in the visibility and attenuation with respect to the concentration of aerosol particles (suspended elemental particles) is done. This research work is conducted and dust model is designed in the atmosphere of urban area of Lahore city. The model deals the effect of the size of the dust particles on the visibility of FSO link and suggests a formula for the calculation of attenuation generated in the link.

In the considered multi‐agent system, the nonlinearities are more stronger than those under the Lipschitz condition, and the existence of the uncertain time‐varying control coefficient causes the invalidation of the full‐order observer. Under such situation, the reduced‐order observers are designed, and the filters are introduced to handle the uncertainties of the input unmodeled dynamics. By adopting the backstepping method, the sampled‐data consensus protocols are developed, and by selecting an appropriate Lyapunov function candidate, we can demonstrate that the practical leader‐following consensus can be achieved for the considered multi‐agent system by the developed protocols with the suitable design constants and an allowable sampling period. Finally, the effectiveness of the proposed consensus method is illustrated by two simulation examples.

Noticing that the focused multiagent system features nonlinearities with non‐Lipschitz restriction, and the outputs of the agents are detectable only at the sampling instants, a reduced‐order observer with the sampled output measurement is established for each follower to evaluate the unavailable velocity, and the distributed finite‐time sampled‐data consensus protocols, which are constructed by the established reduced‐order observer as well as the sampled output measurement of the agents, are developed by combining the techniques of adding a power integral and backstepping. By selecting a suitable Lyapunov function candidate, we can verify that the developed sampled‐data consensus protocols which work under the allowable sampling period and the appropriate design parameters can solve the considered practical finite‐time output consensus problem. Finally, two simulation examples, include a numerical and an engineering simulations, are provided to reveal the effectiveness and availability of the proposed consensus scheme.

Particularly, OLSR (table driven) and DSR (Event driven) protocol are considered. The nodes of MANET establish the connections with each other energetically and can move freely in any direction. In mobile Adhoc network, environment event driven and table driven protocols have significant subject matter of study. There is a mobility issue which matters the service performance due to breakage and renewal of links of mobile nodes. Protocols performance has significance on overall performance of MANET. The aim of this study is to present the performance analysis of selected routing protocols by varying the node densities and WLAN physical characteristics. The voice and video traffic applications are configured discretely by using OLSR and DSR in scenarios. Moreover, for the performance observation the parameters are jitter, traffic received, traffic sent, end-to-end delay, traffic load, and throughput.

By making use of this technology, the swarm of unmanned aerial vehicles (UAVs) forms a network in which the UAVs can communicate with each other and trigger the information for a particular operation of military and civilian applications. The UAV nodes frequently face design issues and power limitations , which affect the routing mechanism. It is a unique challenge for the researchers to introduce the efficient power and routing mechanism that can improve the performance of UAVs' communication networks. However, the concept of cross layer design and efficient power algorithm proposed in this paper increases the performance of UAVCN. The proposed approach integrates the layers 1,2,3 (physical, link, and network). By implementing this kind of approach, an efficient power optimized link state routing (EPOLSR) protocol introduced in this research modifies the conventional OLSR. The EPOLSR and OLSR are implemented and assessed in the first experiment scenario of UAVs communication networks by using an optimized network engineering tool. Moreover, the EPOLSR, OLSR, AODV, and DSR are implemented and assessed in the second experiment scenario. In these testbed experiments, it has been observed that EPOLSR performs better than other routing protocols for UAVs communication networks by increasing the throughput and minimizing the delay.

It has the critical differences with existing wireless networks, which are high mobility, high speed, dynamic updates, and changes in topology due to high movement, which creates the problem of link breakages and affects the routing performance. This problem degrades the performance of UAVCN in terms; it decreases throughput and minimizes the packet delivery ratio. In this paper, we have tried to overcome this problem by considering the received signal power strength (RSPS). We have proposed an algorithm which uses the received signal power strength and time and calculates the link breakage time prediction by using the interpolation method. We have implemented the proposed technique by modifying the OLSR protocol. The extended protocol termed EPOLSR, which efficiently using the signal power strength and time and increasing the performance of UAVCN. The extended protocol implemented by using a research tool network simulator (v3). The metrics received rate, no of received packets, throughput, and packet delivery ratio (PDR) is considered for evaluation. We have examined the proposed EPOLSR with existing routing protocols. It has been observed that the modified protocol performs better concerning all existing evaluated routing approaches.
