Advanced quality of services with security integration in wireless sensor networks

Abstract : In this paper, we focus on the coexistence between security and quality of services (QoS) guarantee in wireless sensor networks. The idea is to integrate the security services: authentication, integrity, confidentiality, and non-repudiation with QoS guarantee. In literature, the major proposed solutions consider QoS and security separately. In addition, it has been shown that it is difficult to offer the end-users multiple levels of security while offering a high level of QoS, because security and QoS are opposite parameters. To tackle this main issue, we propose a new model based on proportional integral derivative controller in order to dynamically select the security level adapted to QoS requirements while considering the energy consumption. The stability parameters in terms of security level and QoS are taken into account by using the principle of proportional integral derivative which is based on the past parameters (history), the current system state (present), and the predictable system change (future). In order to evaluate the proposed model, we consider the case of routing protocol, and we introduce this model into the well-known ad-hoc on-demand distance vector (AODV) protocol called QwS-AODV protocol. Unlike the classical secure AODV, the QwS-AODV protocol aims at adding or removing security services dynamically according to the network performance. Moreover, the validation and the evaluation of the proposed solution are carried out by simulation. The performance evaluation is presented with different network parameters such as throughput, delay, energy consumption, and security services. In addition, the comparison with a classical secure AODV is carried out, and the results obtained with the simulation illustrate that the security is always ensured with lower costs in terms of QoS and energy consumption.
