On the Delivery Probability Study in Mobile Ad Hoc Networks

The delivery probability is an important metric to evaluate the mobile ad hoc networks (MANETs for short) performance. To investigate it in MANETs, we construct a Markov chain to characterize a given routing protocol with multicast traffic mode. In the routing protocol, a source can send up to $f$ copies of the packet to different relays, they can send the copies of the packet to all $g$ destinations until the end of packet lifetime T, and a destination can also send the copy of the packet to another with probability p. With this Markov chain, we can obtain an analytical delivery probability expression. Finally, we provide numerical results to validate the delivery probability expression and to demonstrate how the delivery probability performance varies with network parameters.
