These scheduled based on a semi-persistent scheduling algorithm 3GPP avoid resource contention....

The name data network is an information-based to support futuristic internet traffic. However, the application of naïve NDN in underwater environment not efficient; because it broadcasts packets that increases load, and decreases communication efficiency. So, we proposed novel cluster-based AUV scheme for malicious detection information dissemination within minimum delay. It clusters AUVs based on common interest only enables H-AUV exchange inter/intracluster communication. results show...
