This got me thinking in what if there was an Attack + Special attack version of the eviolite (basically it boosts the ATK and Special ATK of the Pokemon holding it if it can still evolve). What Pokemon could use it, who would benefit from it and who would be better from their evolutions?

Hence, the child node is treated as a malicious node. The rank attack has several effects, such as (1) un-optimized route formulation, (2) un-recognized formulated loop, (3) the RPL network topology never utilized the optimized routing, (4) when the malicious nodes increase, there will be a decrease in the PDR and small modification of the end-to-end delay, and (5) there will be an increase in the DIO messages due to the rapid changes in the network topology. Consequently, the network constrained merits are influenced, such as the energy consumption, delay, packet delivery ratio, and control overhead [15]. Unauthorized access by attackers or third parties to data routing in the RPL networks can make the RPL security a severe problem that shall be considered [16].

The authors in [20] designed a Specification-Based IDS. To detect attacks, this system uses Finite State Machine (FSM) transitions, and Monitoring Nodes (MN) are formed in the monitoring architecture. To detect a rank attack, the malicious nodes with lower ranks are scanned by the MN. The MN will suspect action changes of the valid rank and the fake rank of the malicious nodes. The information cross-checking of the MN will be started to detect the valid ranks. The study in [21] proposed a secure parent node selection scheme, in which, based on a threshold value, a legitimate node will be selected by the child nodes as their parent node. Every node in the RPL network decides the rank value that is advertised by the neighbor nodes based on the threshold between the maximum and average rank. If the rank value is too low, it will be selected as a parent node. The evaluation results of the scheme show that it is effective in decreasing the linking of the child nodes with the malicious nodes.

The study in [26] proposed and implemented a rank and version number authentication security measure scheme based on one-way hash chains called Version Number and Rank Authentication (VeRA). This provides security against internal attacks that broadcast an incremented version number or a higher rank in the DIO messages. The version number is checked for whether it was updated by the root node or not and whether the rank value of the parent node is illegitimately increasing or not. The evaluation results show the overhead time of the scheme. Perrey et al. [27] proposed and designed a Trust Anchor Interconnection Loop (TRAIL) scheme to overcome the obstacles in the former study [26] by analyzing the incompleteness of the rank authentication message. The sink node works as a trust anchor, and every node in the RPL network validates each rank value and drops invalid rank values.

To mitigate the effects of the version number attacks, the researchers in [29] proposed and designed a lightweight approach. Every node in the RPL network executes independent algorithms, in which the state of the nodes is not stored. The evaluation results indicated that the proposed scheme was lightweight and compatible with constrained devices. The research in [14] proposed and implemented lightweight techniques for version number attacks to consider the version number legitimate update. The elimination technique eliminates the malicious update influences of the version number. A trust mechanism is used by the shield technique, in which a change to the version number is required if the majority of the neighbor nodes that are close to the root node have a better rank. The evaluation results indicate that it is possible to mitigate the version number attack using these techniques.

Phase Three: We combine the research work [13,14] and add new features to them, which are a monitoring table, blacklist table, and an alert function to detect, mitigate, and isolate both types of attack. Table 1 compares our work and the changes added to the work of [13,14]. If the DIO message of the sender node does not have a greater version number than the version number of the root node (assuming that the root node cannot be compromised), then it will be a case of rank attack detection and mitigation. If the DIO message of the sender node has a version number greater than the version number of the root node, then it will be the case of version number attack detection and mitigation.

Phase Four: Figure 1 shows the conditions for rank attack detection, mitigation, and isolation, which are added to the research [13]. If the Node Current Rank (NCR) is greater than the Node Parent Rank (NPR), then it is considered to be a malicious node. If the DIO control message of the malicious node is not discarded and is falsely verified as a legitimate node in the monitoring table for any reason, then the monitoring table will be updated to remove all information of the malicious node to restrict it from being a parent node. The malicious node will be added to the blacklist table (which is formulated during the DODAG construction), which captures all information of the malicious nodes to mitigate the effect of the malicious node from the network. The blacklist table contains the IDs of all malicious nodes that should not join the RPL network topology again because they were previously detected as malicious nodes. Then, an alert message will be sent to all the nodes in the network to notify them not to join this node in the future; thus, the malicious node is isolated from the network.

Phase Five: Figure 2 shows the conditions for the version number attack detection, mitigation, and isolation, which is added to the research [14]. If the DIO message of the sender node has a greater version number than the version number in the root node, then the rank rule of the parent node is compared with the rank rule of the current node. If the NPR is greater than the NCR, then it is considered as a mobile node in the RPL network. However, if the NPR is lower than the NCR, then the rank rule of the previous node is compared with the rank rule of the current node. If the NPVR is greater than the NCR, then it is considered a mobile node in the RPL network. However, if the NPVR is lower than the NCR, then the version field of the sender node is updated in the neighbor list table.

The effect of the version number attack in RPL+Shield [14] was almost tripled in the grid-center topology, even though this provided mitigation of the attack compared with our SRPL-RP (Version Number Attack). These results show that the best average results for PDR can be extracted in the grid-center topology. This is because the nodes are placed in uniform distribution and densities, and this topology ensures that each node can reach only its vertical and horizontal neighbors during the simulation. Thus, this influences the RPL network and the number of parent nodes and child nodes that are created by the DODAG, in which a smaller number of parent nodes serve more child nodes.

In the grid-random topology and random topology, each node may have more parent nodes. Hence, the parent nodes allow most of their child nodes to listen to the control messages. Thus, the DODAG of the RPL network can be constructed with more control messages. Therefore, PDR mainly depends on the node distribution and network topology; thus, nodes that have more child nodes have a higher probability of having a higher PDR. When the malicious nodes are closer to the root node, they can be easily detected by the proposed protocol. This is because, when the malicious nodes are far from the root node, it may take longer for the root node to realize that there is a change in the network. As a result, it becomes harder to be detected, and by the time the changes are recognized in the network by the root node, the rest of the legitimate nodes can be affected by the attack.

We found that SRPL-RP in the random topology, SRPL-RP (Rank Attack) in the random topology, and SRPL-RP (Version Number Attack) in the random topology had the lowest and best performance in reducing the redundant amount of produced control messages compared with other topologies and compared with Standard RPL with Attacks, SBIDS [13], and RPL+Shield [14]. On the other hand, the effects of the attacks in Standard RPL with Attacks were higher in the grid-center topology. In addition, the number of generated control messages in SBIDS [13] is higher in the grid-center topology. Additionally, RPL+Shield [14] had more generated control messages even after applying the mitigation mechanism, especially in the random topology.

This shows that the best average results for a control message were extracted in the random topology. This is due to the nature of topologies in which the malicious nodes spread in a random topology faster than in the grid-center and grid-random topologies that have a unified nature. This affects the number of parents and child nodes that create the DODAG and that have more parent nodes in random placements, in which the parent nodes allow fewer of their child nodes to listen to the control messages. Thus, the DODAG of the RPL network can be constructed with more control messages. Hence, the proposed SRPL-RP can reduce the effect of excess generated control messages and successfully mitigate the effect of the attacks. Thus, it prevents the malicious nodes from rebuilding the DODAG with higher parent nodes, and fewer control messages will be generated.

The above analysis and discussion clarify that the proposed SRPL-RP was better in comparison with existing countermeasures in terms of the network performance and detection and mitigation accuracy. On the basis of the comparison in Table 15 of studies in the literature and the proposed SRPL-RP, we demonstrated that the proposed SRPL-RP can provide better functionalities, better network performance, and better detection accuracy. In addition, SRPL-RP supports against multiple attacks at the same time on the network. The effectiveness of the proposed SRPL-RP in terms of the network performance was better: in the grid-center topology for PDR, the best result obtained was 98.48%. In the random topology for the control message value, the best result obtained was 991 packets/s. In the random topology for average energy consumption, the best result obtained was 1231.778 joules. However, the effectiveness of the proposed SRPL-RP in terms of the accuracy was better: in the random topology of SRPL-RP (Version Number Attack) for AR, the best result obtained was 98.17% for the aforementioned reasons. The reason for this is that the proposed SRPL-RP can provide verification of the sender nodes by using the threshold. After the detection occurs, mitigation and isolation features can be applied to cope with the severe effects of both attacks. 2351a5e196
