Abstract: Much research works have been done in terms routing methods for wireless-optical broadband access network (WOBAN), which aims to reduce the packet transfer delay in the network or to improve the availability of the network. However, they are often considered separately. In the current era, both transfer delay and availability are important performance indicators to ensure that information is delivered to the destination on time and efficiently. Hence, in this paper, we propose two different routing methods that aim to improve not only the packet transfer delay of the network but also not neglecting the availability of the network, for the front end of the WOBAN. The first algorithm, DAAR, is a single path routing method which balances both delay and availability (Algorithm 1). The second algorithm is broken down into two parts, 2PRA, which is a simplified form of multipath routing which uses two paths to further improve the delay of DAAR (Algorithm 2a) and DAARM (Algorithm 2b), which is an improved version of 2PRA which uses two paths for routing the packets but also improving the availability of 2PRA. Extensive simulation results show that by using multipath routing methods, we are able to improve the delay of the network however the availability of the network will be affected. Hence, different routing methods will be preferred based on the type of applications, for example, whether it is delay sensitive or not and it is always a matter of trade-off between delay and availability.
