Maximizing network lifetime using coverage sets scheduling in wireless sensor networks

Ad Hoc Networks, 2020
In a Wireless Sensor Network (WSN), when a large amount of sensors are randomly deployed into a detection area, an efficient sleep/active scheduling for sensors to maximize the network lifetime of target (or detection area) coverage, which is called the ...

Enhancement of WSN Network Lifetime

2020 32nd International Conference on Microelectronics (ICM), 2020
Extending WSN lifetime is a crucial problem, designing, developing, and implementing energy-efficient protocols for WSNs is one of the most research challenges. Researchers went toward finding more efficient solutions by proposing new routing protocols or enhancing existing protocols to extend the network/battery lifetime.

Network lifetime optimization in wireless sensor networks

IEEE Journal on Selected Areas in Communications, 2010
Network lifetime (NL) is a critical metric in the design of energy-constrained wireless sensor networks (WSNs). In this paper, we investigate a joint optimal design of the physical, medium access control (MAC) and routing layers to maximize NL of a multiple-sources and single-sink (MSSS) WSN with energy constraints. The problem of NL maximization (NLM)
