On the Lifetime of Wireless Sensor Networks
ACM Transactions on Sensor Networks, 2009Network lifetime has become the key characteristic for evaluating sensor networks in an application-specific way. Especially the availability of nodes, the sensor coverage, and the connectivity have been included in discussions on network lifetime. Even quality of service measures can be reduced to lifetime considerations.

Enhancement of WSN Network Lifetime
2020 32nd International Conference on Microelectronics (ICM), 2020Extending 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.

On the Lifetime of Wireless Sensor Networks
IEEE Communications Letters, 2005We derive a general formula for the lifetime-of wireless sensor networks which holds independently of the underlying network model including network architecture and protocol, data collection initiation, lifetime definition, channel fading characteristics, and energy consumption model.

2011 International Conference on Advances in Social Networks Analysis and Mining, 2011
Online social network (OSN) operators are interested in promoting usage among their users, and try a variety of strategies to encourage use. Some recruit celebrities to their site, some allow third parties to develop applications that run on their sites, and all have features intended to encourage use.

On the Lifetime of Large Scale Sensor Networks
Computer Communications, 2006Network lifetime is an important metric for battery operated sensor networks. In this paper, we study the lifetime of a large scale sensor network with n randomly deployed sensors communicating with a base station (BS), where each sensor node has the same probability to sense and report its data to the BS.

Network lifetime optimization in wireless sensor networks
IEEE Journal on Selected Areas in Communications, 2010Network 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)

Extending network lifetime for ALLIANCES
Computer Communications, 2009ALLIANCES is a newly proposed wireless MAC protocol that exploits the cooperation of source nodes and relay nodes to resolve collisions and further improve throughput. Until now, ALLIANCES did not consider energy, which is the most precious commodity of mobile communications.
