Enterprise users require mobility and secure connectivity when they roam and connect to the services offered in the enterprise. Secure connectivity is required when the user connects to the enterprise from an untrusted network. Mobility is beneficial when the user moves, either inside or outside the enterprise network, and acquires a new IP address. This document describes a solution using Mobi...

The main challenges in routing protocols are node mobility, resource constraints, error-prone channel states, and problems with hidden unprotected terminals. This article provides an overview of the protocols, their problems, ways to improve them. cell phone allows communication between two moving units via mobile stations (MS), units, landing units. term "mobile ad hoc network" (MANET) refers ...

The validation of modern software systems on mobile devices needs to incorporate both functional and non-functional requirements. While some progress has been made in validating performance (including power consumption) on current mobile devices, future mobile devices will incorporate multiple processing units, more complex software and hardware that will raise additional challenges. This paper...

With the rapid advances in mobile technology many mobile devices are capable of capturing high quality images and video with their embedded camera. This paper investigates techniques for real-time processing of the resulting images, particularly on-device utilizing a graphical processing unit. Issues and limitations of image processing on mobile devices are discussed, and the performance of gra...

The superior reconfigurability of software defined radio mobile devices has made it the most promising technology on the wireless network and in the communication industry. Despite several advantages, there are still a lot to discuss regarding security, for instance, the radio configuration data download, storage and installation, user’s privacy, and cloning. The objective of this paper is to p...

This paper introduces the Mobile Nested Transactions (MNT) model for transaction processing coordination in groups of mobile devices. The model extends traditional approaches—centralized and distributed—for distributed transaction processing over mobile devices. Under the Nested Transactions approach, sub-transactions—logical work units—processing control is highly flexible and fault-tolerant. ...

Communities of autonomous units are being developed for formal specification and semantic analysis of systems of interacting and mobile components. The autonomous units of a community are rulebased, self-controlled, goal-driven, and operate and move in a common environment. We employ communities of autonomous units to model the dynamic pickup and delivery problem with the general idea to demons...

OBJECTIVE To assess influenza vaccination rates of healthcare workers (HCWs) in neonatal intensive care units (NICUs), pediatric intensive care units (PICUs), and oncology units in Pediatric Prevention Network (PPN) hospitals. PARTICIPANTS Infection control practitioners and HCWs in NICUs, PICUs, and oncology units. METHODS In November 2000, posters, electronic copies of a slide presentatio...

To allow mobile users to continue their work while disconnected, mobile systems usually rely on optimistic replication techniques. In mobile database systems, mobile units cache subsets of the database state and allow disconnected users to perform transactions concurrently. These transactions are later integrated in the master database state. As concurrently performed transactions may conflict,...
