In social sciences COVID-19 based political campaigns and trends on social media have extended their implications in the domain of political communication. The dissemination of COVID-19 news on social media is widespread, however, the political factors influencing the spread of such news are less discussed. To explore these factors, we evaluated empirical data from 390 social media users in Pakistan by applying PLS-SEM modeling. Snowball sampling was implied to collect the data. Political interest, partisanship, political knowledge, and political efficacy were incorporated as antecedents of COVID-19 news sharing on social media. Major findings show political interest as the most significant antecedent of COVID-19 news sharing followed by political knowledge and partisanship. However, political efficacy did not display any significant influence on participants’ intentions of sharing COV...

This scenario encourages investigation of the decisive factors that might draw disengaged citizens into participatory politics. Therefore, this study illustrates the results of a Pakistani sample (n = 410) regarding the role of social media in influencing political participation in online and offline platforms. Five variables were examined using partial least squares (PLS) to see how they influenced online and offline political participation. The OSOR model of communication mediation was used for this purpose. Its implications were extended by simultaneously incorporating three outcome orientations—political expression, political efficacy, and partisanship—as mediators. In addition, we included political interest as an antecedent orientation and social media use as stimuli. Online and offline poli...

Several psychological and structural factors interpreting the relationship between engagement and the consumption of information and cognitive processes have been emphasised through the use of O-S-O-R and O-S-R-O-R communication mediation models. However, there remains a variety of viewpoints concerning theoretical perspectives and thematic patterns, leading to difficulties in obtaining a structured overview and so advance the development of communication mediation research. This study consists of a systematic literature review of 739 articles, published between 2015 and 2020, across three databases, Scopus, Google Scholar and EBSCOhost, resulting in thirty-four being identified as usable for providing a synthesis of current knowledge focusing on new media. This highlights a considerable variation in existing constructions and t...

Vehicular Ad hoc Networks (VANETs) are a network of vehicles that share and analyze real-time data and require a well-organized and efficient data delivery method. The stability of clusters and dynamic topology change in VANETs are the major issues in finding an optimal route amongst the vehicles. The cooperative approach and surprise pounce chasing technique of Harris Hawks in nature serve as the main sources of inspiration for Harris Hawks Optimization. In this technique, several hawks work together to attack a victim from various angles to surprise it. Due to the unpredictable nature of situations and the prey’s fleeing movements, Harris Hawks can exhibit a variety of intelligent strategies. This study proposes a novel route clustering optimization technique that takes into account communication range, the number of no...

Inter process communication and the heterogeneity of resources plays an important role in task scheduling. To achieve the efficiency tasks are assigned to best suited processor while minimizing communication cost. This directly increases the performance and is referred as completion time. Such problems in a distributed system are considered as NP hard problems. Many solutions are proposed in literature for solving this issue. Directed Acyclic Graph (DAG) is also used to solve the issue of performance in distributed networks. A new heuristic is in this paper based on DAG is proposed for task scheduling on tasks order, average communication cost and best available processor/resource. The experimental study shows the proposed approach give promising results. The performance of proposed heuristic is illustrated by comparing the schedule time, efficiency and schedule length with other well-known algorithms for task scheduling.

With the rapid progress in technology, people are searching for a traffic environment where they would have maximum collaboration with their surroundings which comprise other vehicles. It has become a necessity to find such a traffic environment where we have less traffic congestion, minimum chances of a vehicular collision, minimum communication delay, fewer communication errors, and a greater message delivery ratio. For this purpose, a vehicular ad hoc network (VANET) was devised where vehicles were communicating with each other in an infrastructureless environment. In VANET, vehicles communicate in an ad hoc manner and communicate with each other to deliver messages, for infotainment purposes or for warning other vehicles about emergency scenarios. Unmanned aerial vehicle- (UAV-) assisted VANET is one of the emerging fields nowadays. For VANET’s routing efficiency, several routing protocols are being ...

Routing in VANETs is difficult as compared to mobile ad hoc networks (MANETs); topological constraints such as high mobility, node density, and frequent path failure make the VANET routing more challenging. To scale complex routing problems, where static and dynamic routings do not work well, AI-based clustering techniques are introduced. Evolutionary algorithm-based clustering techniques are used to solve such routing problems; moth flame optimization is one of them. In this work, an intelligent moth flame optimization-based clustering (IMOC) for a drone-assisted vehicular network is proposed. This technique is used to provide maximum coverage for the vehicular node with minimum cluster heads (CHs) required for routing. Delivering optimal route by providing end-to-end connectivity with minimum overhead is the core issue addressed in this ar...
