Abstract: Wireless multi-hop ad Hoc network has been widely used in military battlefield, emergency communication and so on. However, due to the complicate characteristics of wireless channel, it is difficult to obtain reliable protection and real-time reliability in practice. A design strategy on protocol parameters for centralized multi-hop ad Hoc network was proposed to maximize the bandwidth utilization under delay constraint. Based on centralized wireless multi-hop ad Hoc network communication mechanism, an end-to-end delay model and a bandwidth utilization model were established, which fully consider the impacts of four aspects of parameters, network, traffic, protocol and channel. It is shown that the centralized scheduling mechanism is more suitable for the smaller network. Finally, an optimization strategy was given to properly design protocol parameters in different network scenarios under delay constraint.

Key words: multi-hop ad Hoc network, centralized, end-to-end delay, bandwidth utilization, network parameters, protocol parameters
