Uma proposta de protocolo token ring sem fio / A Proposal Wireless Token Ring Protocol

Borges, Adroaldo Lazouriano Moreira 23 January 2014 (has links)
O protocolo Token Ring sem o (WTRP) é um protocolo distribuído de controle de acesso ao meio que provê qualidade de serviço em termos de uso de largura de banda e latência limitada. WTRP consiste de nós (estações) que formam topologicamente um anel. Contudo, quando o número de nós em um anel aumenta a latência aumenta e o tempo de reuso de token por parte de um nó em anel também aumenta. Neste trabalho, apresentamos uma versão extendida de WTRP com foco em reduzir a latência, tempo de reuso de token e permitir encaminhamento de dados entre anéis sem aumentar signicativamente o consumo de energia. Para provar o conceito que propomos, implementamos e testamos a nossa versão de WTRP usando simulador de rede - NS. / Wireless Token Ring Protocol (WTRP) is a distributed Medium Access Control protocol that provides quality of service in terms of reserved bandwidth and limited latency]. It consists of nodes or stations structured in ring topology. However, when the number of nodes in a ring increases latency and time of a node reuse token increases. In this work, we present an extended version WTRP that focus on reducing latency, time of token reuse and data forwarding among the rings in a MANet , without suggestive increasing of energy consumption. We have implemented and tested our version of WTRP in network simulator - NS.

Improvement And Development Of High-frequency Wireless Token-ring Protocol

Kurtulus, Taner 01 January 2011 (has links) (PDF)
STANAG 5066 Edition 2 is a node-to-node protocol developed by NATO in order to communicate via HF media. IP integration is made to be able to spread the use of STANAG 5066 protocol. However, this integration made the communication much slower which is already slow. In order to get faster the speed and communicate within single-frequency multi-node network, HFTRP, which is a derivative of WTRP, is developed. This protocol is in two parts, first is a message design for management tokens exchanged by communicating nodes, and second is the algorithms used to create, maintain, and repair the ring of nodes in the network. Scope of this thesis is to find out a faster ring setup, growing procedure and to implement. Beside, finding optimum values of tuning parameters for HFTRP is also in the scope of this thesis.
