Delivery Delay in 3D MANETs with Packet Redundancy

Delivery delay serves as a fundamental performance metric in three-dimensional mobile ad hoc networks (3D MANETs). However, the delivery delay performance in such networks is still largely unknown by now. This paper studies the delivery delay performance in 3D MANETs, which adopts two hop relay scheme with packet redundancy for packet routing. In particular, we develop a general Markov chain model to depict packet delivery process under such a routing scheme. An analytical expression is further derived for delivery delay. Simulation and theoretical results are conducted to validate the accuracy of theoretical delivery delay analysis and to illustrate the impacts of network parameters on delivery delay performance in 3D MANETs.
