Social Network User Lifetime

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.

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)

Maximum Lifetime Broadcasting in Wireless Networks

IEEE Transactions on Computers, 2005
Summary form only given. We consider the problem of broadcasting messages in a wireless energy-limited network so as to maximize network lifetime. An O(e log e) algorithm to construct a broadcast tree that maximizes the critical energy of the network following the broadcast is developed.

Predicting route lifetime for maximizing network lifetime in MANET

2012 International Conference on Computing, Electronics and Electrical Technologies (ICCEET), 2012
In wireless networks, generally nodes operate with batteries for its own normal operation like mobility, packet forwarding. These nodes tend to drain their energy even when it remains in idle mode. In MANETs, this exhaustion of energy will be more due to its infrastructureless nature and mobility.

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.

On enhancing network-lifetime in opportunistic Wireless Sensor Networks

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
Network lifetime has become the key characteristic for evaluating sensor networks in an application-specific way. In this paper, we focus on Mobile Wireless Sensor Networks, which are specific opportunistic networks because of their poor connectivity among the mobile sensors, and thus it is difficult to form a well connected mesh network for ...

Lifetimes of small catalytic networks

Bulletin of Mathematical Biology, 1994
The dynamics of self-replicative molecules (replicators) has been extensively analysed, following the seminal work of \textit{M. Eigen} [Naturwissenschaften 58, 465-523 (1971)], as a bridge between the theory of chemical kinetics and population genetics in the framework of Darwinian evolution.
