DLTDMA: A dynamic layout time division multiple access channel allocation protocol based on real-time geolocation system

In order to meet the needs of real-time and dynamic joining of nodes in wireless real-time geolocation system, fully improve the channel utilization rate, propose a specific DLTDMA protocol that takes targets´ velocity and change into consideration., detect the joining and exiting of target nodes in time, dynamically allocate time slot for them, ensure real-time of the system and at the same time ensure energy saving. Then simulate the DLTDMA protocol using Matlab simulation platform, in order to prove the superiority of real-time and energy-saving characteristic.
