ASSR Technique.pdf

The proposed Adaptive Sensor Sensing Range (ASSR) technique aims to maximize the lifetime of Wireless Sensor Networks (WSN) by adjusting the sensing range of sensors to cover all targets in the network while minimizing energy consumption. Key findings include:

ASSR can improve network lifetime by 20% in small networks and 8% in large networks compared to other recent techniques.
Adaptive sensing range allows for reduced power consumption by minimizing power usage for data transmission.
* The technique considers a sensor network with randomly deployed sensors that can modify their sensing range to save power while achieving maximum monitoring time.

The ASSR technique is compared to other algorithms, including Deterministic Energy Efficient Protocol (DEEP), Adjustable Range Deterministic Energy Efficient Protocol (ADEEP), Distributed Lifetime Coverage Optimization protocol (Dilco), and Adjustable Range Load Balancing Protocol (ALBP). The results show that ASSR outperforms these algorithms in terms of network lifetime.

The paper also discusses related work on sensing range, including heuristic algorithms for coverage problems, smooth sensing range models, and hybrid approaches for maximizing WSN lifetime. The proposed ASSR technique is evaluated through simulations using the NS3 simulator, demonstrating its effectiveness in improving network lifetime.
