This paper evaluates performance of on demand ad hoc routing protocols to handle unidirectional routing protocols. Ad hoc networks will be consisted of nodes of various transmission range in many cases. Thus routing protocols should support route construction using unidirectional links to provide high connectivity and high routing performance with low control overhead. Among existing routing protocols, DSR is typical protocol to support unidirectional routing, but its optimization mechanism is not effectively for unidirectional links and generates substantial control traffic. We have previously proposed a new on demand ad hoc routing method for unidirectional routing called FOCUS. In this paper, FOCUS is evaluated and compared with DSR. Results of simulation show that FOCUS outperforms DSR in the number of transmitted RREQ packets and data packet transmission delay while maintaining route construction performance, and that it is especially effective in high density network.
