Direct broadcast satellite (DBS) also known as Direct-To-Home is a relatively recent development in the world of television distribution. ?Direct broadcast satellite? can either refer to the communications satellites themselves that deliver DBS service or the actual television service. DBS systems are commonly referred to as mini-dish systems. DBS uses the upper portion of the Ku band. Modified DBS systems can also run on C-band satellites and have been used by some networks in the past to get around legislation by some countries against re ....etc

ABSTRACT

Many ad hoc routing protocols are based on some variant
of flooding. Despite various optimizations of flooding,
manyrouting messages are propagated unnecessarily. We
propose a gossiping-based approach, where each node
forwards amessage with some probability, ....etc

This paper presents two efficient flooding algorithms based on 1-hop neighbor information. In the first part of the paper, we consider sender-based flooding algorithms, specifically the algorithm proposed by Liu et al. In their paper, Liu et al. propose a sender-based flooding algorithm that can achieve local optimality by selecting the minimum number of forwarding nodes in the lowest computational time complexity O(n logn), where n is the number of neighbors. We show that this optimality only holds for a subclass of sender-based algorithms. We ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

The problem of cache sharing for supporting data access in mobile ad hoc networks is studied in this paper. The key to this problem is to discover a requested data item in an efficient manner. In the paper, we propose two caching protocols, IXP and DPIP, which distinguish themselves from the existing ones in that they fully exploit in-zone broadcasts to facilitate cache sharing operation. In particular, the DPIP protocol offers an implicit index push property, which is highly useful for enhancing cache hit ratio in the neighborhood of a data re ....etc

AUTO DRIVE SYSTEM
INTRODUCTION
AutoDrive is a system for automatic driving or cars and commercial vehicles on highway
It is a completely automated highway driving system which uses GPS positioning, radars and  inter vehicle signaling to aid driving
By 2030 all major interstates in the US are expected to support AutoDrive lanes with completely automated car and commercial vehicle driving
Any car updated for AutoDrive can enter these lanes and enjoy speed limits of around 13 ....etc

Mobile Ad Hoc Networks (MANETs) are networks in which all nodes are mobile and communicate with each other via wireless connections. Nodes can join or leave at anytime. There is no fixed infrastructure, all nodes are equal and there is no centralized control or overview. There are no designated routers: all nodes can serve as routers for each other, and data packets are forwarded from node to node in a multi-hop fashion.

Since a few years research interest in MANETs has been growing, and especially the design of MANET routing protocols has r ....etc

Definition
These are special purpose devices and computers that just transfer messages from one network to another. Before we look deep into the topic Virtual LAN's, let us see the basic devices used in the network backbone. They are

1. Bridges.
2. Switches.
3. Routers.
4. Gateways.
5. Hubs.

BRIDGES :-Bridges operate at the data page link layer. They connect two LAN segments that use the same data page link and network protocol.

SWITCHES :-Like bridges, switches operate at the data page link layer. Switches connect two or more co ....etc

Multimedia Broadcast Multicast Service (MBMS) is a broadcasting service that can be offered via existing GSM and UMTS cellular networks. The infrastructure offers an option to use an uplink channel for interaction between the service and the user, which is not a straightforward issue in usual broadcast networks, as for example conventional digital television is only a one-way (unidirectional) system. MBMS uses multicast distribution in the core network instead of point-to-point links for each end device .

MBMS will start to be rolled out in ....etc
