Security with Quality-of-Services optimization in Wireless Sensor Networks

Abstract

In this work, we propose a new framework able to ensure the Quality-of-Services (QoS) with different security levels in Wireless Sensor Networks (WSNs). We propose a new model based on the PID (Proportional Integral Derivative) controller in order to dynamically select the security level adapted to QoS requirement while considering the energy consumption. The stability parameters in terms of security level and QoS are taken into account by using the principle of PID which is based on the past variation parameters (history), the current system state (present) and predictable system change (future). We introduce the proposed model in AODV routing protocol called QwS-AODV protocol. Unlike the classical Secure AODV, 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 is carried out by the simulation. The performance evaluation is presented with different network parameters such as: throughput, delay, energy consumption and security services (authentication, confidentiality, Integrity). In addition, the comparison with a classical Secure AODV is done, and the results obtained from the simulation illustrate that the security is always ensured with lower costs in terms of QoS and energy consumption.

Systematic-RLNC Based Secure and QoS Centric Routing Scheme for WSNs

“…Similar QoS-based routing protocols have also been introduced to enhance overall performance of the network. A framework capable of incorporating QoS with dissimilar security levels in WSNs and a model based on a PID controller was proposed in [4] to dynamically select the security level adapted to QoS and energy utilization levels. Steadiness factors affecting the security level and QoS are considered by employing the principle of a PID based on the past difference, the present scheme state (current) and expected scheme variation (future).…”

A survey on mobility management protocols in Wireless Sensor Networks based on 6LoWPAN technology

“…Hence, mobility support protocol should use authentication and confidentiality, as it is used by HWSN6 [27][28] [29], "Sensor Proxy Mobile IPv6" (SPMIPv6) [54] [55]. However, in WSN based on 6LoWPAN, it's important to optimize the cost of security by taking into account the resources constraints [56][57] [58].…”

“…This point is recommended because performing a supplementary security mechanism requires more processing, memory and bandwidth, which are limited in this network type [27]. For this reason, it is recommended that the mobility support protocol should optimize the security cost according to the available resources (power, transmission rate,etc) [56][57] [58]. In contrast, for the outside of the LoWPAN, the protocol may perform a mechanism [28] such as "IPSec" [70].…”

Advanced quality of services with security integration in wireless sensor networks

“…Unlike existing works, which focus on security, QoS and energy separately, we propose in this work an extension of our solution based on the optimization of security services and QoS parameters by using proportional integral derivative (PID) controller from the feedback control theory . In this paper, we do not focus on proposing a new security mechanism or trust model, but we propose a framework based on PID controller able to integrate the security and QoS metrics in order to dynamically select the adapted security level.…”
