This study analyzes Ni Luh Djelantik's political communication in building leadership image through Instagram account @niluhdjelantik using Hanna Pitkin's Political Representation Theory framework. A descriptive qualitative research method was applied involving nine informants consisting of the account owner, Instagram account admin, political communication academic, and six active followers in Denpasar City through semi-structured in-depth interviews, content observation, and documentation study. The results show that Ni Luh Djelantik's political communication successfully builds a strong leadership image through the integration of four representation dimensions: (1) formal representation through DPD RI legitimacy that strengthens credibility; (2) descriptive representation through identity as a Balinese woman with activist and entrepreneur background that creates emotional closeness; (3) symbolic representation through assertive communication style and use of Balinese cultural symbols that reinforces authenticity; (4) substantive representation through content containing constructive criticism, educational information, and solutions relevant to Balinese community needs. The integration of these four dimensions forms a holistic leadership image: brave, honest, caring for grassroots communities, rooted in local values, and responsive to actual problems. The research confirms that Instagram has transformed political communication to become more interactive and participatory, functioning as a "24-hour digital aspiration office" that opens direct access between people's representatives and constituents, and is effective in building legitimacy and mobilizing political participation among young generation.

Modern technology necessitates the use of dependable, fast, and inexpensive networks as the backbone for data transmission. Switched Ethernet coupled with the Time Sensitive Networking
The World Wide Web WWW has arguably been the most popular application of the Internet for years. Over a period of time, it has developed over the principles of host centric IP internet. However, the limitations of todays host centric IP internet have motivated many future internet architectures that are centered around alternate principals such as content and services.
This paper aims to provide a robust grounding for the additive increase factor used in the `TCP-Friendly' mode of the CUBIC congestion control algorithm.
A generic interface for determining the next hop(s) for a DTN bundle is a valuable contribution to DTN research and development as it decouples the topology-independent elements of bundle processing from the topology-dependent forwarding decision. We introduce a concept that greatly increases flexibility regarding the evaluation and deployment of DTN forwarding and routing techniques and facilitates the development of software stacks applicable to heterogeneous topologies.
In this paper, we review well-known handovers algorithms in satellite environment. The modern research trends and contributions are proposed and summarized in order to overcome their considering problems in satellite-air-ground integrated network environment caused by the fast movement of Low Earth Orbit (LEO) satellite and related frequent handover occurrences.
We introduce a general and comprehensive model for the design and optimization of Virtual Networks, and for the related concept of Network Slicing. The model is flexible, so that by adjusting some of its elements, it can accommodate many different specific cases of importance. Yet, surprisingly, it still allows efficient optimization, in the sense that the global optimum can be well approximated by efficient algorithms.
We show experimentally that workload-based AP-STA associations can improve system throughput significantly. We present a predictive model that guides optimal resource allocations in dense Wi-Fi networks and achieves 72-77% of the optimal throughput with varying training data set sizes using a 3-day trace of real cable modem traffic.
In Content Centric Networks, where one retrieves data based on a given name, not a conventional connection to a server or other device, there is a need for a standard mechanism to establish bi-directional streams. We describe a method to open and maintain such conversations using the techniques of a named data network.
In this technical report, we provide an in-depth description of the Stochastic Network Calculator tool. This tool is designed to compute and automatically optimize performance bounds in queueing networks using the methodology of stochastic network calculus.
Smart optical networks are the next evolution of programmable networking and programmable automation of optical networks, with human-in-the-loop network control and management. The paper discusses this evolution and the role of Artificial Intelligence (AI).
The Ethernet as we see it today is a result of many stages of evolution. As a result, the Ethernet frame format at the link layer also has seen many changes. One might expect a consistent format of link layer frames as we usually study in text books, in actual practice this is not the case. Please refer to the manuscript for complete abstract.
We present a brief summary of current approaches and challenges in the network traffic management area. In this contribution, we well cover the most recent experiments on the network traffic and behavior of applications under various network conditions. Quality of the users' experience is the most important factor being considered in this group of experiments.
We solve the maximum lifetime problem for the point-to-point and point-to-multipoint broadcast data transmission in one dimensional regular sensor network. Based on the analytical solution of the problem for one dimension we propose an algorithm solving the maximum lifetime broadcasting problem for point-to-point data transmission for any dimension.
We describe a distributed framework for resources management in peer-to-peer networks leading to golden-rule reciprocity, a kind of one-versus-rest tit-for-tat, so that the delays experienced by any given peer's messages in the rest of the network are proportional to those experienced by others' messages at that peer.
By analyzing the source codes of ns-2, we discuss the simulated implementations of wireless channels, network interfaces and mostly the 802.11 MAC protocol in ns-2. We also notice the "bugs" of the 802.11 simulation compared with the reality, and present an extension to fading channels as well.
Internet traffic displays many persistent periodicities (oscillations) on a large range of time scales. This paper describes the measurement methodology to detect Internet traffic periodicities and also describes the main periodicities in Internet traffic.
