“…It is notable that security usually comes with a cost in terms of performance degradation [26], [27], thus the tradeoffs between security and other network performance should be carefully addressed for a practical multi-hop ad hoc network. In [40], [41] and our previous work [42], the issue of integrating security and quality of service (QoS) under some network scenarios was investigated. In [43], [44], the security-reliability tradeoff was explored in cooperative relay networks and cognitive radio systems, respectively, where the two-hop network scenarios were considered and corresponding optimal relay selection schemes were proposed.…”

Abstract-The application of physical layer security in ad hoc networks has attracted considerable academic attention recently. However, the available studies mainly focus on the single-hop and two-hop network scenarios, and the price in terms of degradation of communication quality of service (QoS) caused by improving security is largely uninvestigated. As a step to address these issues, this paper explores the physical layer securityaware routing and performance tradeoffs in a multi-hop ad hoc network. Specifically, for any given end-to-end path we first derive its connection outage probability (COP) and secrecy outage probability (SOP) in closed-form, which serve as the performance metrics of communication QoS and transmission security, respectively. Based on the closed-form expressions, we then study the security-QoS tradeoffs to minimize COP (resp. SOP) conditioned on that SOP (resp. COP) is guaranteed. With the help of analysis of a given path, we further propose the routing algorithms which can achieve the optimal performance tradeoffs for any pair of source and destination nodes in a distributed manner. Finally, simulation and numerical results are presented to validate the efficiency of our theoretical analysis, as well as to illustrate the security-QoS tradeoffs and the routing performance.

“…Expression (41) indicates that the routing problem for SO-COP is equivalent to finding the shortest path connecting the pair of source and destination nodes. It means that we can assign the link weights d S k ,D k to each potential link l k and then find the path Π * with the minimum total link weights.…”

“…The main constraint considered in the placement decision is the incurred cost as the scheme aims at minimizing the total resources allocated to ensure a predetermined protection level. In [32], a protection-level based scheme is also proposed whereby the protection level changes in an agile manner as per changes in the QoS requirements of the target services. Overall, resilience and security in cloud has been heavily investigated through many research projects such as SECCRIT [33].…”

International audienceTo cope with the tremendous growth in mobile data traffic on one hand, and the modest average revenue peruser on the other hand, mobile operators have been exploring network virtualization and cloud computing technologies to build cost-efficient and elastic mobile networks and to have them offered as a cloud service. In such cloud-based mobile networks,ensuring service resilience is an important challenge to tackle. Indeed, high availability and service reliability are importantrequirements of carrier grade, but not necessarily intrinsic features of cloud computing. Building a system that requiresthe five nines reliability on a platform that may not always grant it is therefore a hurdle. Effectively, in carrier cloud, serviceresilience can be heavily impacted by a failure of any network function (NF) running on a virtual machine (VM). In this paper,we introduce a framework, along with efficient and proactive restoration mechanisms, to ensure service resilience in carriercloud. As restoration of a NF failure impacts a potential number of users, adequate network overload control mechanisms are alsoproposed. A mathematical model is developed to evaluate the performance of the proposed mechanisms. The obtained resultsare encouraging and demonstrate that the proposed mechanisms efficiently achieve their design goals

“…Our approach provides a formal validation of the framework, which is not done by their negotiation protocol. Taleb and Hadjadj‐Aoul had proposed a scheme to ensure quality of service after policy integration in MANET. As our system is an offline module, it does not need such protocols.…”

It is increasingly important to implement a conflict‐free access control policies for co‐allied networks where different organizations are involve for a common goal. Mobile ad hoc networks are widely used for mission critical situations where teams from different organizational networks cooperate to form a single network to implement their respective operations. These teams (or quads) have different sets of local policies enforced for their own security resulting heterogeneity in access control. Each team wants to preserve its access control policies at a maximum level. Moreover, a set of allied policies govern the cooperation and interaction between the different teams, which may conflict with their local policies. The policy conflicts arise from the transitivity of policy rules, mobility of the nodes, cooperative behaviors, and so on. In addition, the policy rules may be temporal or static. To achieve the successful completion of the mission, it may be required to compromise with the stringency of the enforcement of the conflicting rules for the quads. In this paper, we propose an automated and formal framework to find the optimal conciliation of the policy rules to preserve the mission and thus ensure minimal compromise with the enforcement of policy for each quad. The efficacy of the work lies on optimizing the enforcement of access control policies to achieve the coalition instead of negating the policy. Copyright © 2014 John Wiley & Sons, Ltd.
