Abstract

Internet of things (IoT) requires an internet network for data communication between machines. Wifi is not always available outdoors and requires more portable data communication. This study aims to design a prototype Wireless Sensor Network (WSN) based on nRF24L01 and solar-powered SIM800l for outdoor IoT implementation. The study used a total of five IoT devices with four nodes with nRF24L01 and one node with nRF24L01 and SIM800l. Each device uses an Arduino nano, TP4056, 6WP solar panel, and a 900mAh 18650 battery. The evaluation of the system includes a comparative QoS analysis, namely packet delivery ratio (PDR), throughput, and delay in star and bus topology through data collection of observation methods by sensors. The evaluation results show that for unidirectional data communication the star topology has better results with PDR 99,099%, throughput 99.393%, and delay 0.0095s. While the bus topology produces a slight difference in PDR 98.766%, throughput 98.461%, and delay 0.017s. Evaluation of energy availability shows that during the day with an average voltage of 3.703v and at night 2.976v, there is no significant difference. During the day it produces 99.301% PDR, 99.653% throughput, and 0.001s delay, while at night it produces 94.221% PDR, 99.881% throughput, and 0.027s delay.

Abstract

Data confidentiality and resource's limitation issues are challenges for the Internet of Things. To implement good security on IoT systems, cryptography can do it, but it needs an effective encryption algorithm that does not require a lot of resources. The purpose of this study is to secure an IoT system by implementing an algorithm that is successful in maintaining the confidentiality of data transmitted. This research uses an experimental approach, by creating an IoT system for agriculture and adding an encryption algorithm. The IoT system uses NodeMCU as a microcontroller. NodeMCU is a microcontroller with small resources so it needs an efficient algorithm to be implemented in it. One algorithm that has good performance in a desktop computing environment is the Advance Encryption Standard (AES) algorithm. The algorithm is tested in an IoT computing environment with a data exchange architecture using an REST (Representational State Transfer) web service, resulting in an IoT system for agriculture with cryptographic implementations in it. In the tests carried out, the encryption process of 128 and 256 bits of plain text took 266.31 and 274.31 microseconds, while the memory used was 16% and 17% of the total memory, respectively. This shows the encryption time is fast, and the memory usage is relatively small.

Abstract

One sector that greatly influences it is in terms of network security. This is due to the characteristics of the MANET network that are dynamic so that the MANET network is very easily disturbed by irresponsible parties. One of the attacks that can occur in MANET network is Route Request (RREQ) Flooding Attacks. In RREQ flooding attacks in the form of fake nodes that are outside the area of the network and broadcast RREQ to the destination node in the network, so that it meets the bandwidth capacity which results in a decrease in quality in determining the route of sending data or information to the destination node. To prevent the occurrence of RREQ flooding attacks, a prevention method for these attacks is required, namely the RREQ Flooding Attacks Prevention (RFAP). This method works by finding nodes that are likely to be malicious nodes then isolated from the network to be restored to normal nodes. This research will optimize the AODV and AOMDV routing protocols by adding RFAP prevention methods and knowing the performance of the two protocols in terms of throughput, average end-to-end delay and normalized routing load. Based on the results of the simulation, that the application of the method RFAP on AODV routing protocol can produce network quality is better than AOMDV protocol, both in terms of throughput, average end-to-end delay and normalized routing load.

Abstract

VANET is part of the Mobile Ad-hoc Network (MANET), but the nodes on VANET have a higher level of mobility. Each node that moves will cause network activity (topology changes) such as route search and message sending handled by each node. So that each node must have a routing protocol to facilitate communication in the network. The selection of the appropriate routing protocol is needed in urban and rural scenarios.This study aims to determine the effect of propagation model variants on data communication on the TORA, MDART and ZRP routing protocols on the VANET network on the Praya City and Bypass Lombok road maps with an area of ​​1000x1000 m2. For the variation of the routing protocol using four variations of the propagation model, namely the freespace propagation model, tworayground, shadowing, and nakagami. The number of nodes used in the Praya City road map is 35, 55, 70 nodes and in Lombok Bypass 25, 40, 60 nodes. The test parameters used are throughput, packet delivery ratio and end to end delay.In an urban scenario with an area of ​​1000x1000 m2, the TORA protocol gets a very good throughput parameter on nakagami propagation of 40.95 Kbps and on the ZRP protocol the value of the freespace propagation parameter PDR is 100%. While in the rural scenario a good value is obtained in freespace propagation is 4.82 second. Keywords: VANET, Routing Protocol, Propagation, NS2

Abstract

VANET is a wireless network that is a derivative of the MANET network. VANET network is one network that can be used to communicate between one vehicle and another vehicle. With the existence of the VANET network, it is expected to be able to improve the safety of drivers on the highway. One of the uses of the AOMDV routing protocol is that it can be used to help the performance of the VANET network, the AOMDV routing protocol. AOMDV routing protocol in conducting route search there are two working mechanisms namely route discovery and route maintenance. The route selection process in the AOMDV routing protocol is to consider the number of hops contained in the AOMDV routing protocol, so that the possibility of a broken link, therefore the need for the application of the method in conducting this research. The ant algorithm is one method that can optimize the process of finding a route in the AOMDV routing protocol. The ant algorithm in carrying out the route search is by calculating the distance between nodes. In the ant algorithm, the route selection is based on the most powerful pheromones, so the route chosen is no longer based on the number of hops. From the results of trials that have been carried out on the AOMDV routing protocol using the ant algorithm can improve the performance of the test throughput parameters of 9.7649 Kbps and the performance of the Packet Delivery Ratio of 11.2838%. Whereas the average end to end delay parameter can reduce the delay by 13.3093ms
