Abstract
Mobile ad hoc network (MANET) is a dynamic multi-hop wireless network that is established by a group of mobile wireless hosts on a shared channel. One of the research issues in MANET is the quality of service (QoS) routing protocol. The objective is to improve the packet delivery ratio in QoS constrained communications in comparison to other well-known protocols that use distributed multi-path routing. In this paper, we present, a new routing protocol to reduce the effects of distrustful environment of MANET by keeping the number of suitable paths as high as possible and distributing the decision mechanism among the nodes on the path. The new protocol uses on-demand route discovery. The source node or the intermediate nodes have no knowledge about the path that will be followed by data packets. Instead, starting with the source node, each node just knows which neighbor declared to be capable of forwarding data packets under given delay constraint to the given destination. Simulations are performed to verify the performance improvement of the proposed protocol.
