Tuning Based Multiconstrained Link Weight Assignment for Optimized Data Transmission

Abstract

Routing is a technique, which is used to setup a route from source node to destination node. The route chosen either be an optimized route with respect to delay, capacity, reliability, or may be other QoS parameters. This dissertation examines the problem of transmitting data from designated source to destination in acyclic network so that the reliability, delay and capacity play the significant role to the transmission of data. There are number of applications at the user end and to give them quality of service (QoS) it’s become necessary to have optimized with application requirement. Path chosen by the network is controlled by the tunable factor to consider the all three factors. The dissertation will discuss the experimental results, time complexity and performance parameters. A time complexity algorithm is presented which guarantees an optimal solution with in a polynomial time. This dissertation constituent of implementation of the tunable performance extensions and examine their usefulness in routing of traffic. Tunable factor gives the better results with all parameter consideration viz. reliability, delay and capacity by doing the trade-off among all parameters for getting the optimum QoS. To implement these proposed approach we used NS-2 tool for our simulation using tcl script language and offline tuning is done on the certain set of values.
