ABSTRACT
Designing of a network which could fulfill most of the requirements is always a challenging task for a researcher. Often this happens either with manual approach or by applying some kind of conventional methods. In both cases results do not have high level of optimality. Evolutionary computation is a beacon of hope in handling complex design problems in an efficient manner. To reduce the effect of congestion, various approaches can be applied at different levels namely over Architecture level and Protocol level. The performance of a protocol completely depends upon the facilities available with existing architectures which are stagnant. Hence our research aims at improving the connectivity according to demand in the network having minimum cost of architecture, which is a better alternative and a very efficient way to handle network congestion and reliability. Such kind of network design is a very tedious task. Hence involment of intelligence incorporated into the network design for automatic synthesis is a must. Automation of this design in this paper is done using genetic algorithm. This paper proposes a technique based on Genetic algorithm, which uses a new method of two point crossover, a different and efficient technique of fitness evaluation and tournament selection. The simulations yielded an automatic network architecture which satisfied the requirement of connectivity and minimum cost, fulfilling the traffic demand all along for varying number of nodes and connectivity constraints.
