Abstract

Message Queuing Transport Telemetry (MQTT) is one of the Internet of Things (IoT) protocols specifically designed for communication between machines that have characteristics that can be used at low power, uses small bandwidth, connectivity in packet delivery and protocols using this technology to publish- subscribe. The MQTT protocol only provides authentication security for security which defaults do not guarantee the security of data in transmission so that data privacy and data integrity are problems in the implementation of the protocol. Therefore, the application of the Message Authentication Code (MAC) method uses the Poly1305-AES algorithm based on block ciphers. Based on testing, the Poly1305-AES algorithm has an increase in memory usage of 0.013MB to publishers and 0.028MB to customers and the Poly1305-AES algorithm can support changes, insertions and substitution data. This study presents the results of the Poly1305-AES algorithm which has a pretty good performance based on the value of increasing memory usage and resistance to attacks.

Abstract

MANET (Mobile Ad hoc Network) is a network that does not have a fixed infrastructure and the nodes in it function as routers to forward the information that is sent. MANET has 3 types of routing protocols, namely proactive, reactive and hybrid routing protocols. AODV (Ad Hoc On Demand Distance Vector) and AOMDV (Ad Hoc On Demand Multipath Distance Vector) are reactive type protocols found on MANET. Security on MANET is a big challenge, because nodes will be connected to one unprotected wireless network. Based on the above problems, the authors made a study entitled Performance Analysis of AODV Protocol and AOMDV Against Active Attacks on MANET (Mobile Ad hoc Network) networks. The results obtained from this study are proven that active attacks in the form of Blackhole and DDoS attacks of type Flooding RREQ Attack affect the performance of the two protocols. Tests in this study were conducted on Network Simulator 2 and measured based on 3 parameters, namely Packet Delivery Ratio, End-To-End Delay, and Normalized Routing Load. The test results show that the lowest value of Packet Delivery Ratio is found in the 100 node scenario using the AOMDV protocol with the type of DDoS attack that is worth 52.00%. While the highest end-to-end delay value is found in the 100 node scenario using the AODV protocol with DDoS attack types that are worth 134.25 ms. The highest average value of Normalized Routing Load is found in the 100 node scenario using the AOMDV protocol with DDoS attack types valued at 158.8.

Abstract

2D platformer game is a genre game where players move characters through a side camera and are required to pass existing obstacles to achieve certain goals. Techniques in game development to add to the playing experience are also growing very rapidly. Can be taken an example of the application of dynamic audio. The use of dynamic audio in the game will provide the advantage of using static audio by entering multiple assets for each movement. This research uses Pure Data to implement dynamic audio in endless 2D game runners. Pure Data has a visual way to program sound, namely by connecting small boxes together with virtual cables. Therefore the use of Pure Data is to apply dynamic audio to endless 2D game runners that are highly preferred with consideration of convenience in applying them. The results of this study prove that from predetermined designs obtained valid results and successfully run on 2D runner endless games that have FPS are not significantly different from the use of static audio. The average FPS obtained is 62.4 FPS for dynamic audio and 62.1 FPS for static audio which can be ignored as well as the application of dynamic audio in 2D Endless Runner Games does not provide performance.

Abstract

The popularity of the racing game genre is still visible today. Factors that supporting the popularity of this genre are speed driving which provides an exciting experience, interesting track variations, stunning graphics, and unique challenges presented by artificial intelligence. An important factor to be developed and in line with the core of the racing game that provides a fun challenge is artificial intelligence. Artificial intelligence behavior that is not varied and easy to guess, or even playing badly will affect the fun of the challenge of racing games. To avoid this, artificial intelligence is needed which is able to learn mindset and imitate human decisions when playing, especially braking decision or gas and brake determination. That is the basis of the Neural Network algorithm implemented for Artificial Intelligence in the Racing Game Starter Kit. The complexity of the code on the machine is simplified by changing the decision process to some intelligent neural networks that are similar to human neurons, especially how it works. Coupled with the adaptation process in a dynamic environment makes this algorithm interesting for AI researchers. By utilizing Cross-Validation, learning this algorithm with human behavior has a similarity rate of 76 percent. In a 10-round trial, the time results showed 12% or 72 seconds faster than the kit's AI, and a stable frame rate with an average of 59 frames per second.

Abstract

This study aims to develop dynamic lighting modules in video games with 2D environments that have endless runner types that use the principle of polygon visibility. One type of graphic effect that exists in video games is dynamic lighting, this effect is generally applied to 3D games where the effect can bring a realistic and immersive impression on the game being played. The implementation of dynamic lighting in 2D games in the previous study was implemented using a method used in 3D games, namely normal mapping, the technique is more commonly used in top-down games and game with isometric style, whereas in the game to be implemented polygon visibility techniques due to game perspective which is seen from the side. In this study, dynamic lighting will be implemented using the concept of polygon visibility because the light nature is the same as the vision concept that exists in the concept of polygon visibility in the flat two-dimensional polygon visibility in this study implemented using raycasting which is shot from a point and spreads like light where light represented by one ray object emitted by the module. Based on the above requirements, dynamic lighting modules will be implemented in 2D endless runner games that produce dynamic lighting modules that are implemented using raycasting that visualize polygon visibility and obtain 100% valid functional test results and fps performance testing of 2 test cases that get fps above 24.
