# Multilayered Network Model for Mobile Network Infrastructure Disruption
## 7 Brief Discussion about Future Steps of Proposed MNM Model
### Security Aspects of Proposed MNM Model  
Security is very important and broadly discussed term in 5G networks. The goals of security solutions are to provide privacy, authentication, integrity, non-repudiation, and confidentiality [49; 50; 51]. Base on heterogeneity of the Internet of Thing-based systems, the proposed systems will need support different solutions and algorithms in the sense of security, privacy, secure transmission of information over the networks, interoperability and data management [52]. Based on the characteristics of networks, we have to take into account different items from the security solutions point of view. In MNM model, the term security gains importance, because this model integrates different types of wireless networks with specific technical challenges to attack vulnerabilities.  
In MNM, public safety is a very important part of the security solution. Our solution enables to increase public safety by possibilities to transport emergency information between users without any infrastructure in a disaster and crisis. We must note that our solution does not record any sensitive information about users, we only deal with technology point of view.  
A second look for security is a network and information security. Each network (MANET, DRONET, WSN, and Sensor) of the MNM model have varied security challenges. In the field of security, we will solve the problem of secure and robust transmission between different a source and destination nodes. Secure routing in sensor networks is a very hard problem due to inherent properties in comparison with MANET, DRONET and different types of wireless networks. In the field of security, our research activities in MNM model will be focused on:  
* secure and robust communication between different wireless networks during disaster situations,
* secure and reliable transmission of the IoT information between a source and destination nodes over the wireless different networks,
* increase information and cybersecurity of the IoT by using the novel cryptographic techniques and blockchain algorithms to eliminate unauthorized access and malicious attacks.  
Due to the nature of the proposed solution of the MNM, we will implement the game theory, namely cooperative, non-cooperative and evolution games to the process of finding reliable and secure communication paths between mobile terminals to transport IoT data. The game theory also gives us the possibilities to select reliable communication paths between terminals regarding the actual situation in the networks, and we will eliminate the different malicious nodes located in the networks.  
Another solution is implementation trust-based routing algorithms to transport of the IoT data between isolated islands of the terminals with limited connectivity. We are working on the blockchain routing algorithm to provide a secure path selection between the source and destination nodes. The main idea of all security solutions is to provide secure communication between mobile terminals to provide robust, reliable and secure communication between mobile terminals to transmission IoT data. Another idea of the MNM is to provide a secure public safety network to communication between different terminals without any infrastructure.
