IP3/DAG Signaling Pathway

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Background:

Wireless multimedia sensor networks (WMSNs) are crucial for industrial applications requiring real-time data processing.
Existing WMSN protocols face challenges in timely multimedia data delivery and network refinement.
Efficient data capture and storage necessitate timely real-time multimedia transmission to the sink.

Purpose of the Study:

To develop a novel adaptive Quality of Service (QoS) routing protocol for WMSNs.
To implement the (m,k)-firm model for processing multimedia streams in industrial environments.
To enhance real-time data transmission and network lifetime in WMSNs.

Main Methods:

Developed a new adaptive QoS routing protocol based on the (m,k)-firm model.
Integrated a multimedia stream processing using the (m,k)-firm format.
Introduced an adaptive real-time protocol and traffic handling scheme for next-hop selection based on flow status and (m,k)-firm requirements.
Implemented two-level adjustments in routing protocol and traffic management for improved packet success rates and reduced packet loss.

Main Results:

The proposed protocol significantly improves the stream dynamic success ratio.
The adaptive routing and traffic handling schemes enhance overall network lifetime.
The system effectively meets (m,k)-firm model requirements across varying traffic loads.
Reduced packet loss was observed due to path setup schemes along previous routes.

Conclusions:

The developed adaptive QoS routing protocol effectively addresses real-time data delivery challenges in WMSNs.
The (m,k)-firm model integration enhances the reliability and efficiency of multimedia stream processing.
The proposed schemes offer a robust solution for industrial WMSN applications, improving performance and longevity.
