Adaptive Information Dissemination Control to Provide Diffdelay for the Internet of Things

Area of Science:

• Internet of Things (IoT)
• Wireless Sensor and Actuator Networks (WSANs)
• Network Communication Protocols

Background:

• WSANs face conflicting Quality of Service (QoS) demands, balancing urgent event speed with communication costs and network longevity.
• Simultaneous satisfaction of diverse QoS requirements (delay, cost, lifetime) is challenging in current WSAN applications.

Purpose of the Study:

• To propose an adaptive communication control based on differentiated delay (ACCDS) scheme.
• To resolve the conflict between urgent information delivery and resource conservation in WSANs.
• To meet varying QoS requirements of different event types within WSANs.

Main Methods:

• Developed an ACCDS scheme where source nodes adaptively adjust Searching Actuator Routings (SARs).
• Differentiated delay sensitivity is used to control the number of SARs sent.
• The scheme aims to maintain network lifetime while adapting communication strategies.

Main Results:

• ACCDS reduces network delay for delay-sensitive events by 11.111%-53.684%.
• ACCDS reduces communication costs for interesting events by 5%-22.308%.
• A trade-off exists, with a potential reduction in network lifetime by approximately 28.713%.

Conclusions:

• ACCDS effectively provides differentiated services by managing delay and communication costs.
• The scheme successfully addresses the conflicting QoS requirements in WSANs.
• ACCDS offers a flexible framework for optimizing network performance based on event criticality.
