Abstract There are two main approaches, static and dynamic, to broadcast algorithms in wireless ad hoc networks. In the static approach, local algorithms determine the status (forwarding/nonforwarding) of each node proactively based on local topology information and a globally known priority function. In this paper, we first show that local broadcast algorithms based on the static approach cannot achieve a good approximation factor to the optimum solution (an NP-hard problem). However, we show that a constant approximation factor is achievable ....etc

packet scheduling algorithms matlab code

A network scheduler, also called packet scheduler, is an arbiter program on a node in packet switching communication network. It manages the sequence of network packets in the transmit and receive queues of the network interface controller, which is a circular data buffer. There are several network schedulers available for the different operating system kernels, that implement many of the existing network scheduling algorithms.

The network scheduler logic decides, in a way similar to statistical multip ....etc

Traditionally packet switching networks have supported only best-effort traffic. Newer applications need communication services that allow end clients to transport data with performance guarantees given in terms of delay, delay variation, bandwidth, and loss rate. The choice of the packet scheduling algorithm to be used at switching nodes is very crucial to provide the quality of service.
We have conducted a literature survey covering various scheduling disciplines that can be used to provide performance guarantees to clien ....etc

Packet classification algorithms


Introduction
The process of categorizing packets into flows in an internet router is called packet classification.Packet classification is needed for non best-effort services, such as firewalls and quality of service, service s that require the capability to distinguish and isolate traffic in different flows for suitable processing. Packet classification can be done on a single field or multiple fields. There are a variety of algorithms proposed for packet classification. Th ....etc
