Cost Efficient Low Convergence ONU Placement Algorithm for Deployment of Fiber-Wireless (FiWi) Access Networks

Abstract

Fiber-Wireless (FiWi) access networks provide an impressive platform for the emerging future applications by integrating the merits of optical networks and wireless networks. It offers reliability, robustness, long distance communication, high bandwidth of optical network and mobility, flexibility at a lower cost of wireless network. One of the major issues of FiWi network is its installation cost, which depends on the number of ONUs present in the network. In order to make a cost effective network, we propose cost efficient low convergence (CELC) ONU placement algorithm using particle swarm optimization (PSO) technique. Initially, we place the ONUs at the center region of each grid. We select a global best ONU, communicating with maximum number of wireless routers of the network through multihop way. In order to get optimal ONU position, we apply PSO algorithm. To minimize the required number of ONUs in the network, we form the sets of subordinate wireless routers for each ONU. Finally, we eliminate those ONUs whose associated wireless routers are already connected with any other ONU. The results show that CELC converges faster and requires less execution time than other existing algorithms. Moreover, the numbers of ONUs required using CELC are optimum. Hence, this algorithm provides optimal solution for deployment of cost-efficient network.
