“…We also would like to implement our architecture in open eHealth/mHealth clouds and compare the differences in their operation. We want to adapt our architecture to other kind of networks and technologies, such as mesh networks and spontaneous ad-hoc networks [53] and try to work with other type of data such as multimedia content. Finally, we will study the energy consumption of all the nodes of the network in all these new implementations.…”

Lloret, J.; Sendra, S.; Jimenez, JM.; Parra-Boronat, L. (2016). Providing security and fault tolerance in P2P connections between clouds for mHealth services. Peer-to-Peer Networking and Applications. 9 (5) Abstract:The mobile health (mHealth) and electronic health (eHealth) systems are useful to maintain a correct administration of health information and services. However, it is mandatory to ensure a secure data transmission and in case of a node failure, the system should not fall down. This fact is important because several vital systems could depend on this infrastructure. On the other hand, a cloud does not have infinite computational and storage resources in its infrastructure or would not provide all type of services. For this reason, it is important to establish an interrelation between clouds using communication protocols in order to provide scalability, efficiency, higher service availability and flexibility which allow the use of services, computing and storage resources of other clouds. In this paper, we propose the architecture and its secure protocol that allows exchanging information, data, services, computing and storage resources between all interconnected mHealth clouds. The system is based on a hierarchic architecture of two layers composed by nodes with different roles. The routing algorithm used to establish the connectivity between the nodes is the shortest path first (SPF), but it can be easily changed by any other one. Our architecture is highly scalable and allows adding new nodes and mHealth clouds easily, while it tries to maintain the load of the cloud balanced. Our protocol design includes node discovery, authentication and fault tolerance. We show the protocol operation and the secure system design. Finally we provide the performance results in a controlled test bench.

“…The proposed models improve the security performance of the wireless networks and enhance the network availability while maintaining the quality of the network performance. With different approach, Lacuesta R. et al in [20,21] proposed the design of secure mechanism use computational cost based on the trust of the users and guarantee a secure protocol between the users and the mesh routers. This proposed mechanism use for secure the spontaneous network.…”

International audienceA mobile ad hoc networks (MANET) is a decentralized, self-organizing, infrastructure-less network andadaptive gathering of independent mobile nodes. Because of the unique characteristics of MANET, themajor issues to develop a routing protocol in MANET are the security aspect and the network performance.In this paper, we propose a new secure protocol called Trust Ad Hoc On-demand Distance Vector (AODV)using trust mechanism. Communication packets are only sent to the trusted neighbor nodes. Trust calculationis based on the behaviors and activities information of each node. It is divided in to trust global (TG)and trust local (TL). TG is a trust calculation based on the total of received routing packets and the totalof sending routing packets. TL is a comparison between total received packets and total forwarded packetsby neighbor node from specific nodes. Nodes conclude the total trust level of its neighbors by accumulatingthe TL and TG values. The performance of Trust AODV is evaluated under denial of service/distributeddenial of service (DOS/DDOS) attack using network simulator NS-2. It is compared with the Trust CrossLayer Secure (TCLS) protocol. Simulation results show that the Trust AODV has a better performance thanTCLS protocol in terms of end-to-end delay, packet delivery ratio, and overhead. Next, we improve theperformance of Trust AODV using ant algorithm. The proposed protocol is called Trust AODV+ Ant.The implementation of ant algorithm in the proposed secure protocol is by adding an ant agent to put thepositive pheromone in the node if the node is trusted. Ant agent is represented as a routing packet. Thepheromone value is saved in the routing table of the node. We modified the original routing table by addingthe pheromone value field. The path communication is selected based on the pheromone concentration andthe shortest path. Trust AODV+ Ant is compared with simple ant routing algorithm (SARA), AODV, andTrust AODV under DOS/DDOS attacks in terms of performance. Simulation results show that the packetdelivery ratio and throughput of the Trust AODV increase after using ant algorithm. However, in termsof end-to-end delay, there is no significant improvement

“…Moreover, we will include geographic routing in order to improve the message forward direction and provide fast and reliable routing mechanisms [28]. Furthermore, we will add the combination of symmetric and asymmetric cryptography in order to provide authentication, data integrity and message encryption, like we have added in our previous work [29].…”

Some public transport vehicles embed devices that allow passengers to connect to Internet while traveling. These vehicles are true mobile Internet access zones inside public paths. These zones could be used by other vehicles moving close to them in order to have Internet access. At the same time, other vehicles in the influence area could be used as relay nodes which would increase this access area. In this paper, we present a group-based protocol and mobility model for vehicular ad hoc networks (VANETs) where each public transport vehicle forms a group of vehicles. They can access and allow access to Internet though the public transport vehicle. Each vehicle is moving inside the group and can leave and join any group at will, while all groups are moving. First, we will show the algorithm and protocol to achieve our purpose. Then, we will study the probability of having Internet access in order to demonstrate that it is a feasible proposal. Finally, we simulate a study case based on real values in order to obtain the performance of our proposal in terms of several network parameters such as the number of hops per route, the network traffic, the page response time, network delay, network load and so on.
