Umpiring security Models for MANETS

Journal of Computer Science and Technology, 2012
In wireless mobile ad hoc networks, packet delivery is achieved through two closely related network-layer operations: ad hoc routing and packet forwarding. As a result any security solution should encompass the protection of both.

Cardiac rhythm devices in heart failure with reduced ejection fraction – role, timing, and optimal use in contemporary practice. European Journal of Heart Failure expert consensus document

European Journal of Heart Failure, EarlyView.
Abstract Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision‐making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices

Mobility Prediction in Wireless Ad Hoc Networks using Neural Networks [PDF]

Journal of Telecommunications, Volume 2, Issue 1, p95-101, April 2010, 2010
Mobility prediction allows estimating the stability of paths in a mobile wireless Ad Hoc networks. Identifying stable paths helps to improve routing by reducing the overhead and the number of connection interruptions. In this paper, we introduce a neural network based method for mobility prediction in Ad Hoc networks.

A study of research trends and issues in wireless ad hoc networks [PDF]

arXiv, 2017
Ad hoc network enables network creation on the fly without support of any predefined infrastructure. The spontaneous erection of networks in anytime and anywhere fashion enables development of various novel applications based on ad hoc networks. However, at the same ad hoc network presents several new challenges.

Blockchain and NoSQL: Enhancing Throughput via a Deep Learning‐Based Hybrid Architecture

Internet Technology Letters, EarlyView.
ABSTRACT Any data structure used to store information can be considered a database. Blockchain technology, at its core, is no more than a ledger to store information about transactions. In recent years, such technology has gained immense popularity in a wide range of applications.

Enhanced group-based wireless ad-hoc sensor network protocol

International Journal of Distributed Sensor Networks, 2016
Communication is the major energy consumption source in wireless ad-hoc sensor networks. Thus, an efficient trade-off between the energy cost of the communication and network’s performance is a key challenge in conceiving a wireless ad-hoc sensor network.

Wireless Sensor Networks Fault-Tolerance Based on Graph Domination with Parallel Scatter Search

Sensors, 2020
In wireless sensor/ad hoc networks, all wireless nodes frequently flood the network channel by transmitting control messages causing “broadcast storm problem”. Thus, inspired by the physical backbone in wired networks, a Virtual Backbone (VB) in wireless
