To enhance hidden node detection capacity and packet delivery ratio in mobile WMSNs.

Main Methods:

The OHND paradigm comprises three phases: hidden node detection, message exchange, and location detection.
OHND enables directional coverage computation for multimedia sensor nodes.
A continuous neighbor discovery process is implemented to manage node mobility.

Main Results:

Simulations using NS2 demonstrate OHND's capability in maintaining direct coverage and detecting hidden nodes.
The proposed algorithms effectively maximize coverage and support multimedia node mobility.
Performance evaluation shows improved metrics compared to existing approaches.

Conclusions:

OHND is an effective solution for enhancing multimedia transmission in WMSNs.
The paradigm addresses key challenges related to node mobility and coverage.
OHND offers significant improvements in energy efficiency and data delivery for WMSNs.
