@article { ISI:000390576800001, title = {Security-Based Mechanism for Proactive Routing Schema Using Game Theory Model}, journal = {MOBILE INFORMATION SYSTEMS}, year = {2016}, abstract = {Game theory may offer a useful mechanism to address many problems in mobile ad hoc networks (MANETs). One of the key concepts in the research field of such networks with Optimized Link State Routing Protocol (OLSR) is the security problem. Relying on applying game theory to study this problem, we consider two strategies during this suggested model: cooperate and not-cooperate. However, in such networks, it is not easy to identify different actions of players. In this paper, we have essentially been inspired from recent advances provided in game theory to propose a new model for security in MANETs. Our proposal presents a powerful tool with a large number of players where interactions are played multiple times. Moreover, each node keeps a cooperation rate (CR) record of other nodes to cope with the behaviors and mitigate aggregate effect of other malicious devices. Additionally, our suggested security mechanism does not only take into consideration security requirements, but also take into account system resources and network performances. The simulation results using Network Simulator 3 are presented to illustrate the effectiveness of the proposal.}, issn = {1574-017X}, doi = {10.1155/2016/5653010}, author = {Amraoui, Hicham and Habbani, Ahmed and Hajami, Abdelmajid and Bilal, Essaid} } @conference { ISI:000358381600012, title = {Effect of selfish behaviour on OLSR and AODV Routing Protocols in MANETs}, booktitle = {2014 GLOBAL SUMMIT ON COMPUTER \& INFORMATION TECHNOLOGY (GSCIT)}, year = {2014}, note = {Global Summit on Computer and Information Technology (GSCIT), Sousse, TUNISIA, JUN 14-16, 2014}, publisher = {IEEE Tunisia Sect; IEEE; Future Technologies \& Innovat}, organization = {IEEE Tunisia Sect; IEEE; Future Technologies \& Innovat}, abstract = {In this paper, we{\textquoteright}ll try to discuss the cooperation of nodes representing one of the important factors in improving the quality of service (QoS) and security in mobile ad hoc networks (MANETs). The routing protocols for MANETs are designed based on the assumption that all participating nodes are fully cooperative. In such networks, the Selfish behaviour is among the big challenges and can lead to the degradation of the network performance. We{\textquoteright}ll introduce this behaviour and. We{\textquoteright}ll propose a new profile to assess the impact on the performance of MANETs: energy, end-to-end delay, routing packets and the packets rate. The Results of simulations using OLSR and AODV protocols have shown that energy-based selfishness is a big problem and could affect the performance in MANETS depending on the mobility of nodes, size and density of the network. We{\textquoteright}ll try to prove that the selfish behaviour can be used to impact quality of service (QoS) and security in MANETS. Therefore, we need a comprehensive mechanism to cope with this behaviour to isolate selfishness nodes and we have planned to publish it in the future work as a new strategy based on game theory to encourage nodes to cooperate.}, isbn = {978-1-4799-5627-2}, author = {Amraoui, Hicham and Habbani, Ahmed and Hajami, Abdelmajid} }
