On improved modeling and simulation of wireless communication systems using multiagent and multi-threading systems architectures for efficient spectrum reuse

Efficient design and evaluation of complex wireless communication systems in terms of spectrum reuse can be accomplished using advanced simulation environments. To this goal, network modelling and simulation methodologies are the most critical issues, thus, several Discrete Event Simulation (DES) schemes have been introduced in the literature. In a real wireless network, services such as new call admission, reallocation, etc, should be offered at the same time for different mobile users in the network coverage area. Thus, the network modelling must be based on the network operational concurrency and services independence. The simulation model adaptation to real network behaviour is a challenging goal. Herein, a novel simulation methodology based on multi-threading for simulating wireless networks, compared to the state of the art approach, is presented, preliminarily analyzed and discussed. Moreover, various implementations based on multi-threading and multi-agent concepts are also presented and evaluated.
