Link Dynamics in Three-dimensional Mobile Ad hoc Networks

3-Dimensional Mobile Ad hoc NETwork (3-D MANET) is a case of mobile Ad hoc network which is distributed on the 3-Dimensional space. Analysis of link dynamics is a fundamental issue in the studies of 3-D MANET, the conclusion of which can be the basis of the design of network protocol. Based on the Constant Velocity (CV) mobility model, analytical expressions of expected link lifetime and its distributions are derived from a probability model. Simulation results verify the accuracy of the analytical expressions. The conclusion is valuable for the research and application of 3-D MANET.
