Sprinkler, a reliable data dissemination service for wireless embedded devices which are constrained in energy, processing speed, and memory. Sprinkler embeds a virtual grid over the network whereby it can locally compute a connected dominating set of the devices to avoid redundant transmissions ,and a transmission schedule to avoid collisions. Sprinkler transmits O(1) times the optimum number of packets in O(1) of the optimum latency; its time complexity is O(1). Thus, Sprinkler is suitable for resource-constrained wireless embedded devices. ....etc

Network Congestion Control Algorithm for Tree Based reliable Multicast Protocols

ABSTRACT

A Congestion Control algorithm for Tree Based reliable Multicast Protocols is a collection of nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Multicasting is to send single copy of a packet to all of those of clients that requested it, and not to send multiple copies of a packet over the same portion of the network, nor to send packets to ....etc

Optimal State Allocation for Multicast Communications with Explicit Multicast Forwarding- IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, VOL. 19, NO. 4, - Java

Abstract—
In this paper, we propose a scalable and adaptive multicast forwarding mechanism based on Explicit Multicast (Xcast). This mechanism optimizes the allocation of forwarding states in routers and can be used to improve the scalability of traditional IP multicast and Source-Specific Multicast. Compared with previous work, our mechanism needs fewer routers in ....etc

MULTI USER SECURITY FOR MULTICAST COMMUNICATION

INTRODUCTION

The simplest computer chatting is a method of sending, receiving, and storing typed messages with a network of users. This network could be WAN (Wide Area Network) or LAN(Local Area Network). Our chatting system will deal only with LAN’s (static IP address) and it is made up of two applications one runs on the server side (any computer on the network you choose it to be the server) while the other is delivered and executed on the client PC. Every time ....etc

Reliable Multicasting in MANETs

Abstract
Multicasting is the transmission of datagramâ„¢s (packets) to a group of zero or more hosts identified by a single destination address. Maintaining group membership information and building an optimal multicast distribution structure (typically in the form of a routing tree) is challenging even in wired networks. However, nodes are increasingly mobile. One particularly challenging environment for multicast is a mobile ad-hoc network (MANET). This report provides an in-dept ....etc

Please, I am Gaisie Michael, a researcher residing in Ghana, in West Africa researching into the modern communication technologies.
I am aware of unicast, broadcast and multicast transmissions.

Please, may I know which one is the most adopted by communication industries, how it is implemented, its strengths and weaknesses and how it can be improved upon as the years go by.

I would be glad if it is presented in a report form or if follows a project procedure.

I am counting on your usual co-operation. Thank you. ....etc

Abstract
Two of the existing reliable transport layer protocols for wireless sensor networks- Distributed TCP Caching and Event To Sink Reliable Transport protocol, does not score well in terms of efficiency. Considering the total number of retransmissions as a QoS parameter for efficiency, our protocol k-RTP ( k Hop Reliable Transport Protocol ) is promising. In our protocol only the nodes do cache the packets and retransmit them in case of packet loss. The value of k is varied dynamically depending on the rate of packet loss in the network. ....etc

SCAMP : SCAlable Multicast Protocol for Communication in Large Groups


This report proposes a new scalable multicast protocol for communication within a large group over Internet. There are many existing and new applications in which the groups involved are very large. An example would be Video-conferencing amongst a large and widely distributed group. The members of such a group can be spread across the entire Internet with no uniformity in their pattern of distribution. In such applications, there will be one or at most a few sources and ....etc

Congestion Control Algorithm for Tree-based Reliable Multicast Protocols

Abstract:
This project contains a detailed description of the congestion control algorithm of tree-based reliable multicast protocol. This algorithm takes advantage of regular acknowledgements from the receivers that propagate back to the sender via the repair tree. This scalable feedback mechanism is used to collect receiver credits. Complementing the windowing mechanism, packet transmission is smoothed by using a data rate commensurate with the window size. A ....etc
