The development and growth of wireless communication for multi-hop communication, has led to many research works particularly in the area of Mobile Ad hoc Networks (MANETs). Despite a large number of investigative and development works on the subject, the research on MANET is considered premature and therefore, many issues need to be addressed. Naturally, the topology of MANETs is frequently changing, where nodes having different attributes and transmission capability, forming connections using limited resources. Such characteristic causes the network to be heterogeneous and as a result, routing paths between nodes can be formed via links that are both symmetrical and asymmetrical. The design of efficient and reliable routing schemes that can exploit and utilise all types of link is therefore, a major challenge in MANET. The key works on this research are to investigate the impact of unidirectional links on the routing path construction and to develop schemes to improve the performance. The Dynamic Reverse Route (DRR), built upon the AODV routing protocol is able to minimise the routing overhead incurred due to multiple route request broadcast.
