There are various concerns in Fiber wireless access networks, such as ONU placement, survivability, network planning andand its cost, architectural developments, etc. In this paper, we have focused on front end survivability of the network, which mainly depends on the routing algorithms employed at the front end of the network.
The effectiveness of the proposed scheme lies in finding the next alternate path in case of link/component failure with minimum delay. Hence, delay is the appropriate parameter to evaluate the efficacy of the proposed technique. In this paper, RSSI-based routing (RBRA) is proposed for various cases of link failures. Delay performance for each of the cases has been compared with two previous approaches maximum protection minimum link cost (MPMLC) andand minimum hop routing algorithm (MHRA).
It is found that RBRA performs better than MPMLC andand MHRA. For single link failure and two source destination pairs in the network with 50 wireless routers delay decreases by 58% andand 37% in RBRA as compared to MHRA andand MPMLC, respectively.
Hence, these algorithms can be integrated with RSSI-based route selection. This could be an attractive future direction for research.
