SiMBCN: An Interactive Simulation Tool for Multihop Based Cellular Networks

Multihop transmission is expected to play a central role in the design of 4G cellular standards. To evaluate the system level performance of multihop based cellular networks, there is a need to develop simulation tools that support relaying capabilities. In this work, we present the design, development, and capabilities of a new simulator for multihop based cellular networks (SiMBCN) that has research and demonstration modes with a user-friendly graphical user interface. The research mode can be used to test a large set of system parameters and advanced enhancement options (multiple relaying, multihop diversity, directional antennas, etc.) using Monte-Carlo simulations whereas the demonstration mode can be used to visualize the network operation and performance in real time. Example results are presented which show the capabilities of relaying in reducing power consumption and combatting shadowing.
