Background: It is paramount to secure the healthcare system from unauthorized users and security attacks through appropriate security mechanisms as a break in the communication process and which leads to leaked or blurred messages, which is totally unacceptable. Moreover, mutual authentication is a core requirement for privacy protection as it is paramount to control who is accessing the sensed data and w Read More

Aim: The existing cluster-based energy-efficient models such as Low Energy Adaptive Clustering Hierarchy (LEACH) and Stable Election Protocol (SEP) unable for the distribution of sensor nodes uniformly during cluster formation. The non-uniform cluster distribution structure leads to rapid energy depletion and high energy consumption. So, this paper aims to create uniform load-based cluster formation. Background: This pr Read More

Background: Over recent years, the security of the publicly available audio, video and text data has become a big challenge, i.e., social media communication; hence the author presents an exceedingly secure communication system to hide the data from an attentive adversary. Objective: The study aims to design and analyze a novel algorithm to be implemented for message transmission using multi-image LSB steganogra Read More

Background: The prime challenge in Parking Systems is to administer the parking during peak hours or peak seasons. Besides being time consuming, it is laborious. Amalgamation of various infrastructures of hardware and software is prodigious and thus adding to its conventional hardware, making the investment in Smart Parking solution highly hazardous and splintered. Electronic payment vendors cause another Read More

Background: The North-Eastern part of Bangladesh suffers from frequent flash flood, causing colossal damage to life and properties, especially the vast croplands. A distributed sensing system can monitor the water level on a continuous basis to warn people near the riverbank beforehand and reduce the damage largely. However, the required communication infrastructure is not available in most of the remote rural areas in a Read More

Background: The Steered Response Power–Phase Transform (SRP-PHAT) approach is a breakthrough in the field of source localization in a high reverberant environment, but the substantial computational cost limits its usage in the practical implementation. Objective: This paper presents an efficient SRP-PHAT based, Iterative Volumetric Reduction (IVR) Steered Response Power method for acoustic source localization in non-id Read More

Background: Wireless Sensor Networks (WSNs) have been researched to be one of the ground-breaking technologies for the remote monitoring of pipeline infrastructure of the Oil and Gas industry. Research has also shown that the preferred deployment approach of the sensor network on pipeline structures follows a linear array of nodes, placed at a distance from each other across the infrastructure length. The linear arra Read More

Background: Due to the generic feature of AOMDV, it is widely used in Long-Term Evolution (LTE) networks such as the Internet which requires new challenges to deploy conversational real-time applications like VoIP (Voice over IP) and video conferencing. Objective: In AOMDV, the multiple routes between any source and destination pair are selected based on minimal hop count which does not ensure reliable video content Read More

Background: The performance of Mobile Ad-hoc Networks gets severely degraded due to various attacks including the Selfish Behaviour attack. The detection of malicious nodes and avoidance of such nodes for data forwarding is important to enhance the MANET’s performance. Methods: A probabilistic model based on Single-Sided Laplacian distribution for the random ON/OFF switching time of this attack is proposed. The m Read More

Background: VANETs (Vehicular Ad-Hoc Networks) are the subclass of MANETs, which have recently emerged. Due to their swift changing topology and high mobility nature, it is challenging to design an efficient routing protocol for routing data amongst both moving vehicles and stationary units in VANETs. In addition, the performance of existing routing protocols is not effective due to the high mobility characteristics of VANETs. M Read More

Background: Many applications of Wireless Sensor Networks (WSNs) require awareness of sensor node’s location but not every sensor node can be equipped with a GPS receiver for localization, due to cost and energy constraints especially for large-scale networks. For localization, many algorithms have been proposed to enable a sensor node to be able to determine its location by utilizing a small number of special nodes Read More
