Probabilistic Multicast Trees in Different Network Topology Environments
نویسندگان
چکیده
Node loss and congestion changes the performance characteristics of the multicast trees. Probabilistic Multicast Trees (PMT) makes use of performance feedback, generates a probability of usage for each multicast tree based on that feedback and then makes intelligent choices about which multicast tree to use for a given packet in the presence of node loss and congestion. The advantage gained by using PMT is that it improves upon the management of the dynamic behavior of the clients where the target connectivity is constantly changing because of its feedback mechanisms and probabilistic tree selection. PMT is inserted onto three network latency topology models in a multiple tree multicast tree environment with positive improvements in the performance of data distribution.

Multicast computer network routing using genetic algorithm and ant colony
Due to the growth and development of computer networks, the importance of the routing topic has been increased. The importance of the use of multicast networks is not negligible nowadays. Many of multimedia programs need to use a communication link to send a packet from a sender to several receivers. To support such programs, there is a need to make an optimal multicast tree to indicate the opt...
متن کاملAn efficient key management scheme for secure wireless multicast
In the future, many multicast services will take place in the wireless domain. However, before these services can successfully be deployed, security infrastructures must be developed that manage the keys needed to provide access control to content. In this paper, we present a method for designing multicast key management trees that are suitable for mobile wireless environments. By matching the ...

As group-oriented services become the focal point of ad hoc network applications, securing the group communications becomes a default requirement. In this paper, we address the problem of group access in secure multicast communications for wireless ad hoc networks. We argue that energy expenditure is a scarce resource for the energy-limited ad hoc network devices and introduce a crosslayer appr...
متن کاملEvaluation of the Open - Source Implementation of PIM - SM
PIM-SM is the routing protocol which describes the exchange of the network topology information in order to construct logical multicast trees. Multicast traffic is routed along these multicast trees in order to more efficiently utilize the network resources. In this paper, we evaluate capabilities of the open-source implementations which allow routing of multicast traffic: Quagga, and Pimd.
متن کاملA Framework for Hierarchical Multicast Routing
We propose a framework for the creation and maintenance of multicast trees in hierarchical networks. This framework aims at coping with an inherent diiculty of topology aggregating in such networks. The main idea of the proposed framework is to distribute the tree topology information among a set of hierarchical Multicast Group Servers (MGSs) nominated for each multicast tree, while keeping reg...
