C21. Analytical analysis of a Cluster Controlled Mobility scheme for data security and reliability in UWSNs

Abstract

This paper investigates the security and data reliability in Unattended Wireless Sensor Networks (UWSNs). We deduce an analytical model for Self-Healing scheme based on Cluster Controlled Mobility (SH-CCM) for UWSNs. The SH-CCM is based on mobility inside a cluster of sick sensor beside the hybrid cooperation from both reactive and proactive peers to enhance self-healing probability. The analytical analysis of SH-CCM will ensure that both mobility and hybrid cooperation from both reactive and proactive peers within the cluster of sick sensor will enhance the Cooperation, Self-Healing, data security and reliability. Therefore, the proposed SH-CCM scheme will help the sick sensor to self-heal and restore its backward secrecy faster and better than the schemes without controlled mobility. A set of Analytical results are carried out to demonstrate the effectiveness of the proposed SH-CCM scheme in the presence of an Adversary (ADY). The obtained results ensure that the proposed scheme has a better performance; it archives a probability of BSe to be compromised of 0.04 while CHSHRD [1] is 0.065.

Trade‐off between self‐healing and energy consumption in mobile unattended WSNs

“…Self‐healing is the process working against the adversary progress, during this process the sick sensor will regain its secrecy and become health again [4–9]. Without self‐healing process, the adversary can occupy the whole network and gradually the network will not be accessible.…”

“…In this paper, changing the sensor location by mobility can be utilised to solve the problem of the leakage of healthy peers and improve cooperation and self‐healing capabilities. This will enhance both data security and reliability in UWSNs [6]. However, sensor mobility is considered as one of the most energy consuming factors in UWSNs.…”

“…In [24, 25] the authors proposed a process calculus for mobile ad‐hoc networks (MANETs) which relies on a behaviour‐based multilevel trust model. However, this model is more complicated when compared to the model presented in [6]. Therefore, in our analysis, we consider the model presented in [6].…”

“…The proposed SH‐SFCMC scheme is a modified version of self‐healing‐cluster controlled mobility (SH‐CCM) scheme proposed in [6]. The major difference is in the mobility sub‐scheme, which is a single flow under control mobility within a cluster, which differs from the cluster‐controlled mobility sub‐scheme presented in [6] in the number, type, and position of the moving sensors. Extensive simulations are carried out to test the performance of the proposed scheme.…”
