A low delay dynamic distributed TDMA slot allocation algorithm for ad hoc networks

Abstract

For the ad hoc network topology is changeable: the network scale becomes larger, which leads to difficulty in network management and lack of efficiency; The diversity of network services (text, pictures, audio, video, etc.) leads to the dynamic occupation of channels by nodes, which easily affects the end-to-end delay and throughput of the network. This study proposes a dynamic distributed TDMA protocol using theoretical analysis and network simulation verification methods. The full connection matrix of nodes is used for distributed scheduling. The influence of TDMA slot allocation on service delay is analyzed in detail. The simulation results of end-to-end delay and throughput of the network are given in the simulation experiment. The simulation shows that this directional routing protocol has some improvements in reducing end-to-end delay, reducing average packet hops, improving channel space reuse rate, and increasing network capacity.
