viagra diabetes Abstract

The employment of contemporary telecommunications technologies like telemedicine and the internet necessitates to decline the centralization of the Bangladeshi’s public healthcare service, and to advance the access to specialty care in small-towns and rural localities. This paper presents a mobile medical data access system which can be used to exchange medical data between medical centers and a remote moving vehicle. The paper concludes with an elucidation of how the proposed approach can be used in telemedicine as a diagnostic tool, and can help to understand the requirements and capabilities for participating in next generation healthcare environments.

get link ABSTRACT:

This paper presents the biological data acquisition and transmission for the remote monitoring of some severe diseases and disorders e.g. Diabetes and Cardiac activity. These types of patients have to need close and continual monitoring in order to prevent further damage. Patient monitoring and the acquired data are transmitted through wireless medium by using BLUETOOTH technology. Bio-signal can be acquired and high frequency noise cancellation also be processed with the help of MATLAB Digital Filter Design Tool (FDA Tool). Data or signal is transmitted to the patients’ mobile continually using BLUETOOTH. Security is the main problem in wireless transmission but it can be solved by using frequency hopping technique which is broadly used in BLUETOOTH technology and moreover, to increase the security level, we can use link level security where the security procedure initiates before the channel established.

source Abstract:

Wireless network security has become a strong requirement for effective deployment of wireless communication applications. There are obviously some reasons for users who like to use wireless technology because of its various benefits. However, as the attacks against WLANs are easier than LAN, the security architectures in WLANs have been discussed frequently. In this paper, the vulnerabilities and weakness of WEP protocol which is used in IEEE 802.11b have been analyzed. A new dynamic key generation scheme that surely enhances the security of WEP (Wired Equivalent Privacy) has been proposed. The proposed method found to be more effective than conventional system.

generic cialis shipping Abstract:

In this paper, the shortest path in a packet switched network has been analyzed. A router receives a packet from a network and passes it to another network calculating the shortest path. However, the packets of a network use different routing protocols. A routing protocol is a combination of rules and procedures that lets routers informs each other of changes. It allows routers to share whatever they know about their neighborhood. Routing protocols are used to continuously update the routing tables that are consulted for forwarding and routing. The primary contribution of this paper is a simulation method of displaying the packet traces which finds the shortest path to route the packet through its destination. The simulation has been done by using Packet Tracer 4.01 software that allows us to stop time in our network and examine traffic in detail.

enter site Abstract

In recent times, the manifestation of telemedicine developments and the wireless networks implementations in the medical field has covered that how we can best exploit wireless technology to afford the medical sector with apposite solutions. In this paper, a system architecture of telemedicine system for remote patients using wireless communication has been proposed. A prototype of Wireless LAN IEEE802.11 is used as a communication channel. The.stored and forwarded packet propagation of wireless communication was implemented by using packet tracer version 4.01.

The emergence of WiMAX has attracted significant interests from all fields of wireless communications. WiMAX has been tipped to bring a revolution in the way where broadband services have been used today; those have been strengthened by the optimization of RF. The systematic investigation to establish facts of necessary modification about the theory for smooth  optimization is targeted. This paper has considered the map outage factor of the objective function for the invention of a method to produce suitable values which help to realize better output. Simulation results found to be more precise over conventional RF of WiMAX in finding the modification of the existing theory.

Universal Mobile Telecommunications System (UMTS) is one of the standards in 3rd generation partnership project (3GPP). Different data rates are offered by UMTS for voice, video conference and other services. This paper presents the performance of UMTS cellular network using sectorization for capacity and coverage. The major contribution is to see the impact of sectorization on capacity and cell coverage in 3G UMTS cellular network. Coverage and capacity are vitally important issues in UMTS cellular Network. Capacity depends on different parameters such as sectorization, energy per bit noise spectral density ratio, voice activity, inter-cell interference and intra-cell interference, soft handoff gain factor, etc and coverage depends on frequency, chip rate, bit rate, mobile maximum power, MS Antenna Gain, EIRP, interference Margin, Noise figure etc. Different parameters that influence the capacity and coverage of UMTS cellular network are simulated using MATLAB 2009a. In this paper, the outputs of simulation for increasing amount of sectorization showed that the number of
users gradually increased. The coverage area also gradually increased.
