Abstract :
This paper presents an EP-TDMA algorithm based on P-TDMA, a collision-avoid and dynamic slots assignment algorithm proposed by Peng. EP-TDMA algorithm adds a novel contention mechanism according to work load, providing improved channel utilization and finite delay guarantee. It is shown to be optimal when the traffic is more heavy and unbalanced. We compare our algorithm with P-TDMA and fixed TDMA algorithm through simulation. The results show EP-TDMA outperforms TDMA and P-TDMA in terms of PDR and ETE delay.
