A 3D signal obstruction model for realistic mobility models in Mobile Ad Hoc Networks

The study of mobile ad hoc networks depends on understanding protocols from simulations before applying them in a real-world setting. The production of a real-world environment within which an ad hoc network can be formed among a set of nodes requires the development of a r ealistic, generic, and comprehensive mobility model to replace random models. Realistic mobility models consist of three sub-models. One of these sub-model is signal obstruction sub-model. Realistic mobility model have previously been proposed and include the Obstacle Mobility Model and the Pathway Mobility Model. These models consider 2D pathways and obstacles that constrain node movements and their signals. In this paper, a new signal obstruction sub-model is proposed that can be used in all realistic mobility models. Proposed model can consider all obstacles of environment in 3D and simulate obstruction of the signals by 3D obstacles. Simulation results show that the 3D obstacles can affect the other parameters of MANET.
