ZTDMA: A multi-zones and multi-objectives channel allocation protocol based on TOA real-time geolocation system

Abstract

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 ZTDMA protocol that divide the geolocation system coverage area into several independent subdomain which can work in parallel. ZTDMA can shorten the average localization period of nodes effectively, and detect the joining and exiting of target nodes in time, dynamically allocate time slot for them, ensure real-time of the system. Then simulate the ZTDMA protocol using OMNet++ simulation platform, in order to prove the superiority of real-time characteristic. © 2014 Springer-Verlag Berlin Heidelberg.
