Incorporating safety risk into the design process is one of the most effective design sciences to enhance the safety of metro station construction. In such a case, the concept of Design for Safety (DFS) has attracted much attention. However, most of the current research overlooks the risk-prediction process in the application of DFS. Therefore, this paper proposes a hybrid risk-prediction framework to enhance the effectiveness of DFS in practice. Firstly, 12 influencing factors related to the safety risk of metro construction are identified by adopting the literature review method and code of construction safety management analysis. Then, a structured interview is used to collect safety risk cases of metro construction projects. Next, a developed support vector machine (SVM) model based on particle swarm optimization (PSO) is presented to predict the safety risk in metro construction, in which the multi-class SVM prediction model with an improved binary tree is designed. The results show that the average accuracy of the test sets is 85.26%, and the PSO–SVM model has a high predictive accuracy for non-linear relationship and small samples. The results show that the average accuracy of the test sets is 85.26%, and the PSO–SVM model has a high predictive accuracy for non-linear relationship and small samples. Finally, the proposed framework is applied to a case study of metro station construction. The prediction results show the PSO–SVM model is applicable and reasonable for safety risk prediction. This research also identifies the most important influencing factors to reduce the safety risk of metro station construction, which provides a guideline for the safety risk prediction of metro construction for design process.

“…AODV protocol is one of the widely used routing protocols in MANETs [49] as it has a wide range of advantages compared with other protocols. AODV is loop-free and scales to a large number of nodes, is adaptable to topology changes and responds to changes quickly, supports both unicast and multicast transmissions, has a minimal routing overhead, and has lower setup delay [50]. Some researchers conduct a performance analysis comparison between the AODV routing protocol and other routing protocols such as OLSR and DSR protocols, while other researchers focus on the performance of the AODV protocol under attack.…”

A Survey on Parameters Affecting MANET Performance

A mobile ad hoc network (MANET) is an infrastructure-less network where mobile nodes can share information through wireless links without dedicated hardware that handles the network routing. MANETs’ nodes create on-the-fly connections with each other to share information, and they frequently join and leave MANET during run time. Therefore, flexibility in MANETs is needed to be able to handle variations in the number of existing network nodes. An effective routing protocol should be used to be able to route data packets within this dynamic network. Lacking centralized infrastructure in MANETs makes it harder to secure communication between network nodes, and this lack of infrastructure makes network nodes vulnerable to harmful attacks. Testbeds might be used to test MANETs under specific conditions, but researchers prefer to use simulators to obtain more flexibility and less cost during MANETs’ environment setup and testing. A MANET’s environment is dependent on the required scenario, and an appropriate choice of the used simulator that fulfills the researcher’s needs is very important. Furthermore, researchers need to define the simulation parameters and the other parameters required by the used routing protocol. In addition, if the MANET’s environment handles some conditions where malicious nodes perform network attacks, the parameters affecting the MANET from the attack perspective need to be understood. This paper collects environmental parameters that might be needed to be able to set up the required environment. To be able to evaluate the network’s performance under attack, different environmental parameters that evaluate the overall performance are also collected. A survey of the literature contribution is performed based on 50 recent papers. Comparison tables and statistical charts are created to show the literature contribution and the used parameters within the scope of the collected papers of our survey. Results show that the NS-2 simulator is the most popular simulator used in MANETs.

“…One approach involves a node broadcasting connectivity information via local hello messages, enabling nearby nodes to listen to these packets and determine connectivity. An alternative approach utilizes a link or network layer mechanism, such as the IEEE802.11 Media Access Control (MAC) protocol [6].…”

This study focuses on enhancing both security and network performance in Mobile Ad Hoc Networks (MANETs) by integrating a trust model with the Ad hoc On-demand Multipath Distance Vector (AOMDV) routing protocol. The inherent structure of MANETs, characterized by dynamic, wireless connections between mobile nodes and a lack of centralized supervision, makes these networks particularly susceptible to security threats. Traditional security solutions designed for fixed networks prove inadequate for the unique challenges posed by ad hoc networks. We explore the benefits of multipath routing, which establishes multiple paths between source and destination nodes, thereby improving the reliability of data transmission and achieving load balancing. However, these benefits are undermined without a robust security framework. To this end, we introduce a trust model as a key mechanism for enhancing security. Trust is not only crucial for decision-making but also vital for the design and analysis of secure distribution systems. By assessing the trustworthiness of nodes, we aim to enhance both security and routing performance. Simulation results suggest that our proposed trust-based routing protocol is effective. Detailed findings will elucidate how this integrated approach can address the pervasive security challenges in MANETs while optimizing network performance.
