ABSTRACT

With the Information age in full and rapid development, users are becoming accustomed to having immediate access to information. Users demand more capabilities from every kind of electronic devices, more processing power, more features and better connectivity. Users are also realizing the benefits of collaborating with others in their communities to help expand the body of knowledge. One user that understands the benefits of information sharing is the United States Department of Defense. The DoD’s Networks-centric enterpris ....etc

Abstract:
The communication requirements for space missions necessitate to address the problems due to deep space communication networks. the effects of slow start algorithm, propagation delay and the page link errors on the throughput performance of transport layer protocols are investigated in deep space communication networks. The objective of this seminar is to demonstrate through existing TCP protocols are far from satisfying the deep space communication requirements and point out the urgent need for new TCP solutions. ....etc

Performance Analysis of CSMA/CA protocol in IEEE 802.11 Networks using Backoff mechanism

Abstract: The distributed coordination function (DCF) in the IEEE 802.11 standard for wireless LAN is based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) like medium access control protocol. This collision avoidance is implemented by means of backoff procedure which uses a rotating window mechanism. This paper presents a simulation analysis of the slot selection probabilities and the backoff mechanism. The ....etc

Explicit Load Balancing Technique for NGEO Satellite IP Networks With On-Board Processing Capabilities

Abstract

Non-geostationary (NGEO) satellite communication systems offer an array of advantages over their terrestrial and geostationary counterparts. They are seen as an integral part of nextgeneration ubiquitous communication systems. Given the non-uniform distribution of users in satellite footprints, due to several geographical and/or climatic constraints, some Inter-Satellite Links (ISLs) are expected to be heavily loaded with data ....etc

Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc

Mobility Management Approaches for Mobile IP Networks: Performance Comparison and Use Recommendations- NETWORKING

Abstract”In wireless networks, efficient management of mobility is a crucial issue to support mobile users. The Mobile Internet Protocol (MIP) has been proposed to support global mobility in IP networks. Several mobility management strategies have been proposed which aim reducing the signaling traffic related to the Mobile Terminals (MTs) registration with the Home Agents (HAs) whenever their Care-of-Addresses (CoAs) chang ....etc

Satellite Networks
What is a satellite?
A satellite is basically any object that revolves around a planet in a circular or elliptical path.
Orbits
The path a satellite follows is an orbit.
There are three basic orbits
Geostationary Earth Orbit (GEO)
Low Earth Orbit (LEO)
Medium Earth Orbit (MEO)
Geostationary Earth 0rbit (GEO)
Geostationary Earth Orbit (GEO)
GEO satellites orbit the earth directly over the equator, approximately ....etc

Abstract
Mobile Ad Hoc Networks (MANET) are self-organizing multi-hop wireless networks. The MANETs are rapidly deplorable due to the absence of a fixed infrastruc- ture. A number of routing protocols have been proposed in solving routing problems for this type of network to provide and maintain better connectivity in the network. Before being implemented in real life the performance of a routing protocol is eval- uated primarily through the simulation experiments. This paper presents Taguchiâ„¢s method to optimize networks parameters ....etc

Abstract

Satellite networks provides wide coverage of geographic area and high bandwidth. As satellite capacity is often limiting resource which must be used efficiently. Internet traffic is highly bursty in nature and Demand Assignment Multiple Access (DAMA) techniques are suitable provide bandwidth to match instantaneous requirements and provide significant improvements in the delay/utilization performance of Geo-stationary Earth Orbit (GEO) satellite channels supporting a finite number of users ....etc
