| Abstract | A disaster is an unpredictable phenomenon. Recently, emergency communication infrastructures for disaster management have become an area of interest for a number of researchers. For emergency networks, MAC protocols play an important role and need to be designed differently from those for normal communications. In this research study, simulation is carried out to measure the performance of the MAC protocol for ad-hoc emergency wireless networks proposed in (Saengudomlert, et al., 2005a), where only approximated analytical results were presented. In this protocol, tree splitting is used to resolve contentions among packets transmitted by survivors towards a common base station. Performances of single-hop and multi-hop versions of the protocol are evaluated and compared. Simulation results verified the analytical prediction that multi-hop protocols can be more time and energy efficient than the single-hop protocol. In addition, simulation results keep track of the percentages of isolated survivors who fail to make contact to the base station due to the absence of any multi-hop path from individual survivors to the base station. In general, as the average number of hops in the multi-hop protocol increases, the protocol spends less time and energy. However, this saving in time and energy is limited since the percentages of isolated survivors eventually become significant as the number of hops increases |
