Congestion Control for Efficient Transmission in ZigBee Networks
INTRODUCTION
 ZigBee is a leading wireless network technology with low cost, low power based on IEEE 802.15.4
 Recently, ZigBee networks are rapidly developed because of its low cost, low power and high reliability characteristic
 Congestion control is necessary technique in order to guarantee a reliable transmission and network efficiency
 ZigBee provides retransmission and acknowledgment (A ....etc

Almost all internet applications like the streaming media and internet telephone favour reliability than time. This factor makes the TCP factor a less preferred choice. Even the UDP network cannot make up to this level as it is in short of the congestion control. These congested controlled networks are usually causes great risk factors for the use of high bandwidth UDP applications. So naturally there was need for designing a congestion-controlled unreliable transport protocol. The result, Data gram Congestion Control Protocol or DCCP gets adde ....etc

Datagram Congestion Control Protocol (DCCP)
Abstract
Fast-growing Internet applications like streaming media and telephony prefer timeliness to reliability, making TCP a poor fit. Unfortunately, UDP, the natural alternative, lacks con- gestion control. High-bandwidth UDP applications must im- plement congestion control themselvesa difficult taskor risk rendering congested networks unusable. We set out to ease the safe deploymentofthese applicationsbydesigninga congestion-controlledunreliable transport protocol. The out- come, the Data ....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

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

Analysis of Datagram Congestion Control Protocol


ABSTRACT
In the last decade, there has been an enormous increase in the need to stream line data. Some of the primary applications like Voice over IP, Video Conferencing, music, and video streaming etc, need continuous flow, and transmission in real time, and consume a large amount of bandwidth. Data streaming usually employs one o ....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
