Abstract

The Internet of Things (IoT) has unique design requirements compared to typical network devices, particularly regarding energy efficiency and performance expectations. To meet the need for low power consumption and easy integration with existing IP network devices, 6LoWPAN is a viable option. 6LoWPAN is an adaptation layer that enables efficient transport of IPv6 packets within small link layer frames, such as those defined by IEEE 802.15.4. In this study, we conducted experiments to compare the delay and throughput performance of 6LoWPAN to the legacy CSMA/CA protocol, which uses IPv4 for addressing. In the experiment, NS3 was utilized to construct separate network system architectures for 6LoWPAN and CSMA/CA. The tests were conducted individually based on various research scenarios, with each scenario comprising 50 to 750 nodes and utilizing the same traffic type. The results were visualized for ease of comparison and analysis. Our experiment revealed that CSMA/CA outperforms 6LoWPAN in terms of both throughput and delay. Specifically, the average throughput of CSMA/CA was 2.345 times greater than that of 6LoWPAN, while the average delay was 2.54 times shorter.

Abstract

Penelitian ini bertujuan untuk melakukan analisis perbandingan konsumsi energi protokol routing Path Aware - Ad hoc On-Demand Multipath Distance Vector (PA-AOMDV) dan AOMDV standar pada jaringan Mobile Ad hoc Network (MANET). Penelitian dilakukan untuk mengetahui perbedaan konsumsi energi antara kedua protokol routing tersebut dan menentukan protokol routing mana yang lebih efisien dalam penggunaan energi di situasi tertentu. Penelitian ini menggunakan network simulator NS-2 untuk mensimulasikan jaringan dengan parameter skenario simulasi yang telah ditentukan kemudian membandingkan konsumsi energi dari kedua protokol routing tersebut. Data yang dihasilkan dari simulasi kemudian dianalisis dan dibandingkan untuk menentukan protokol routing yang lebih efisien dalam penggunaan energi pada jaringan MANET. Hasil dari penelitian ini menunjukkan bahwa protokol routing PA-AOMDV memiliki konsumsi energi yang lebih rendah dibandingkan dengan AOMDV standar pada skenario jumlah node 50 dan 100. Namun, pada skenario jumlah node 25, perbandingan konsumsi energi kedua protokol routing tersebut tidak terlalu signifikan. Oleh karena itu, untuk topologi jaringan dengan jumlah node yang sangat banyak dengan network area yang luas, penggunaan protokol routing PA-AOMDV lebih disarankan untuk menghemat konsumsi energi.

Abstract

The rapid movement of nodes and signal interference in Mobile Ad Hoc Networks (MANETs) cause communication routes to become unstable and often lead to packet loss. One of the major drawbacks of the Destination Sequenced Distance Vector (DSDV) protocol is its inability to maintain optimal network performance under such conditions. To address this issue, this study proposes a modification of the DSDV protocol by implementing a node's residual time prediction algorithm, named TimePrediction-DSDV, to enhance route stability and reduce the impact of signal interference. Simulations were conducted using Network Simulator version 2.35 on the Linux Ubuntu 14.04 operating system, with node density scenarios of 25, 50, and 100 nodes, and speeds of 30, 60, and 90 m/s in a 1500x1500 meter squared area. The performance parameters tested included throughput, end-to-end delay, and packet delivery ratio (PDR). The simulation results show that TimePrediction-DSDV significantly improves performance across all scenarios. For the throughput test, the average increase was 15% for 25 nodes, 14.5% for 50 nodes, and 13% for 100 nodes. For the end-to-end delay test, the decrease was 22% for 25 nodes, 20.8% for 50 nodes, and 19.5% for 100 nodes. For the Packet Delivery Ratio (PDR) test, the increase was 12.5% for 25 nodes, 11.6% for 50 nodes, and 10.67% for 100 nodes. Although network performance decreases with increased node density and speed, TimePrediction-DSDV consistently shows better results compared to the standard DSDV in all tested scenarios.

Abstract

Rapid topology changes in Mobile Ad Hoc Networks due to node movement often cause network instability. Each node in the network can move freely with varying speeds in different directions. As a result, the connection between devices can be disconnected or reconnected depending on the different communication ranges. Node movement causes constraints on the communication path created by AOMDV, because it does not take into account node mobility, so AOMDV has difficulty in maintaining route stability. This study aims to improve the performance of the AOMDV routing protocol in MANET by using the TimePrediction algorithm to improve the calculation of node movement during the route search process. This approach involves modifying the "Hello" message so that the position and speed information of neighboring nodes, which will be sent gradually to ensure communication between nodes. adding location and speed information of each device into the message that will be sent by each other. The TimePrediction protocol was created to overcome the problem of a constantly changing network. By predicting where nodes in the network will move, this protocol can also create a more stable communication path. The results showed that the TimePrediction AOMDV protocol successfully increased the average throughput by 5.39% for 50 nodes, 6.48% for 75 nodes, and 6.87% for 100 nodes. In addition, the average end-to-end delay decreased by 5.39% for 50 nodes, 6.48% for 75 nodes, and 6.87% for 100 nodes. The packet delivery ratio also increased by an average of 7.19% for 50 nodes, 8.80% for 75 nodes, and 12.70% for 100 nodes.

Abstract

The movement of nodes in a Mobile Ad Hoc Network (MANET) is very dynamic and unpredictable. Each node in this network moves freely at different speeds and directions, which causes continuous changes in the network topology. The movement of nodes affects the communication path between nodes, as connec-tions between nodes are lost or re-established according to the position of the node whether it is still with-in communication range or not. In addition, the movement of nodes also affects the performance of rout-ing protocols used in finding routes, such as AODV (Ad hoc On-Demand Distance Vector). The AODV routing protocol does not take into account the movement of neighboring nodes in finding routes, so the route found can be quickly disconnected because the nodes involved in the route move away, out of range of the communication signal. This research aims to improve the performance of the AODV routing proto-col by considering the movement of nodes in the route finding process using the TimePrediction algorithm. The approach used includes modifications to Hello messages, so that they also include position and ve-locity information of neighboring nodes. Hello messages are packets sent periodically by each node in a MANET network to inform neighboring nodes of its presence. The results show that from a given node speed variation, TimePrediction-AODV routing protocol is able to provide better average throughput im-provement of 8.63% for 20 nodes, 29.10% for 40 nodes, and 60.70% for 60 nodes, better average PDR improvement of 6.06% for 20 nodes, 20.54% for 40 nodes, and 27.50% for 60 nodes, and average end-to-end delay reduction of 31.53% for 20 nodes, 28.86% for 40 nodes, and 43.98% for 60 nodes compared to standard AODV.

Abstract

The distance of nodes when communicating is a major challenge in route finding. The long distance of nodes will consume a lot of energy in the routing process so that the occurrence of failure or disconnection of the routing path becomes a problem that needs to be considered. One of the weaknesses in the AOMDV protocol is that it does not pay attention to node distance and node energy in the routing process. Therefore, this research proposes to modify the standard AOMDV routing protocol by adding the Preserving Energy Optimization Algorithm to identify node selection based on the node's distance to the source node by considering the node's energy in the routing process. The approach used includes modifications to the Hello message, so that the message has a geographic location based on x and y coordinates. The simulation was conducted using NS-2.35 on Linux Ubuntu operating system. The test parameters include energy consumption, end-to-end delay and packet delivery ratio (PDR). The simulation results of applying the PEO-AOMDV algorithm provide significant performance on all tested parameters. In terms of energy consumption, there is a saving of 16.04%. In addition, there is a decrease in average end-to-end delay by 43.08% to an increase in PDR percentage by 15.17% at various node density variations.
