Abstract

Abstract:

In the existing literature of performance modeling and analysis of centralized multi-hop networks, the models almost did not deal with the impacts of protocol parameters, resulting in lack of theoretical support for the protocol design in practical scenarios. Regarding this problem, the schedule delay and effective throughput models which fully consider the network parameters, service parameters as well as protocol parameters were proposed. The models and numerical simulation show the impacts of parameters such as the number of nodes, network bandwidth, the number and average hop-count of service flows, proportion of control slots and bit number within one slot. The optimization strategy of proportion of control slots and bit number within one slot under various network scenarios and service requirements were further obtained.

Key words: multi-hop, centralized scheduling, delay, effective throughput, protocol parameters
