Optimized Routing Algorithm of Ad-hoc Mobile Network with Unidirectional Links:AODVUD

Mobile ad hoc routing protocols are designed based on bidirectional links,but there are many unidirectional links in real environment,and they have bad effect on the routing protocols. In this paper we propose AODVUD,which is an optimized routing algorithm for ad hoc network with unidirectional links. AODVUD is based on the AODV routing protocol and uses some optimized method to improve the performance,which are routing discovery,bidirectional link sensory and on-demand routing maintain. Simulation experiment shows that AODVUD evidently increases the packet delivery ratio and has superiority compared with AODV and AODVUU.
