An Efficient Scheme for Secure Data Transmission in Wireless Sensor Networks
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we propose an efficient security scheme for wireless sensor networks which provides good level of confidentiality and authenticity of the data that are transmitted from the sensors to the base station. We use one-way hash chain and pre-stored shared secret keys for ensuring the data transmission security in the network. In our scheme

Heterogeneous Distributed Sensor Networks (Hdsn)
Research Output | Dar Al-hikmah Library | IIUM Only

A new deployment model of distributed sensor network is presented where sensors with different functional types participate at the same time. In this model the sensors are associated with different deployment sets but they cooperate with each other within and out of their respective sets. We term this network model as Heterogeneous Distributed Sens

A Novel and Efficient Bilateral Remote User Authentication Scheme Using Smart Cards
Research Output | Dar Al-hikmah Library | IIUM Only

This paper proposes a novel remote user authentication scheme using smart cards which allows both the authentication server (AS) and the user to verify each other’s authenticity. Our scheme is efficient enough to resist the known attacks that could be launched against remote user authentication process.P2-4 Abstract --This paper proposes a novel

A Secure and Efficient Way of Node Membership Verification in Wireless Sensor Networks
Research Output | Dar Al-hikmah Library | IIUM Only

This paper proposes an efficient mechanism of node membership verification within the groups of sensors in a wireless sensor network (WSN). We utilize one-way accumulator to check the memberships of the legitimate nodes in a secure way. Our scheme also supports the addition and deletion of nodes in the groups in the network. Our analysis shows that

Speculation Vis a Vis Faith and Reason in Islam and Christianity: Medieval Attempts at Incorporating Reason with Revelation.
Research Output | Dar Al-hikmah Library | IIUM Only

• Abstract: Medieval philosophers were confident that they must and could interpret and assimilate philosophy i.e. Greek philosophy into the religious ethos. The medieval philosophers' reasoning on why it was necessary to incorporate philosophy into the religious ethos is because philosophy provided the proofs for theoretical opinions in reli

Modeling and Fabrication of Cmos Surface Acoustic Wave Resonators
Research Output | Dar Al-hikmah Library | IIUM Only

A fully integrated two-port surface acoustic wave (SAW) resonator, fabricated using a standard 0.6- m complementary metal–oxide semiconductor (CMOS) process is described in this paper. Only three micromachining processes, namely, reactive ion etching, zinc–oxide deposition, and wet etching, implemented subsequent to the standard process, are re

A Case Study on the Effect of Imputing the Missing Variability Measures in Meta Analysis
Research Output | Dar Al-hikmah Library | IIUM Only

A Meta Analysis is a statistical technique for integrating quantitative results of the same research question from several sources. It is being applied in various disciplines including the medical and social sciences research,. One of the common problems with meta analysis data is when the variability measures, specifically, the standard deviations

Securing Sensor Reports in Wireless Sensor Networks
Research Output | Dar Al-hikmah Library | IIUM Only

The sensor reports from a wireless sensor network are often used extensively in the decision making process in many systems and applications. Hence, classifying real and false sensor reports is necessary to avoid unwanted results. In this paper, we propose a scheme for securing the sensor reports in a wireless sensor network. We use one-way hash ch

Developing a Secure Mechanism for bluetooth-Based Wireless Personal Area Networks (Wpans)
Research Output | Dar Al-hikmah Library | IIUM Only

This paper highlights our work in developing an enhanced security framework for Bluetooth-based wireless personal area networks (WPANs). The basic security architecture of Bluetooth, operating at the link layer, is augmented with a higher application layer security mechanism for authentication and message integrity. This is necessary since the pres

A Note on Berge Equilibrium
Research Output | Dar Al-hikmah Library | IIUM Only

This work is a contribution on the problem of the existence of Berge equilibrium. Abalo and Kostreva give an existence theorem for this equilibrium that appears in the papers [K.Y. Abalo, M.M. Kostreva, Berge equilibrium: Some recent results from fixed-point theorems, Appl. Math. Comput. 169 (2005) 624–638; K.Y. Abalo, M.M. Kostreva, Some existen
