Lifetime Modeling of a Sensor Network
Design, Automation and Test in Europe, 2005We provide a mathematical analysis for the lifetime of a sensor network, when data-generation at individual sensor nodes is a random process. We show that the mathematical results for expected lifetime and its probability distribution closely validate the simulations results, both in linear and planar networks.

A Theory for Maximizing the Lifetime of Sensor Networks
IEEE Transactions on Communications, 2007An important issue in wireless sensor networks is the limited energy and bandwidth resources. A novel theory is developed here for maximizing the lifetime of unicast multihop wireless sensor networks. An optimal centralized solution is presented in the form of an iterative algorithm. The algorithm attempts to find a Pareto-optimal (PO) solution. In the

An analysis of the lifetime of OLSR networks
Ad Hoc Networks, 2010The Optimized Link State Routing (OLSR) protocol is a well-known route discovery protocol for ad-hoc networks. OLSR optimizes the flooding of link state information through the network using multipoint relays (MPRs). Only nodes selected as MPRs are responsible for forwarding control traffic.

Lifetime in Wireless Sensor Networks
2009 International Conference on Complex, Intelligent and Software Intensive Systems, 2009The following paper deals with criterion used to measure communication protocol efficiency in Wireless Sensor Networks. As energy is a crucial characteristic of those networks, it is necessary to pay attention both to the energy consumption and to the distribution of energy consumption, when using communication protocols, so as to increase the lifetime

Maximum Lifetime Broadcasting in Wireless Networks
IEEE Transactions on Computers, 2005Summary 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.

On enhancing network-lifetime in opportunistic Wireless Sensor Networks
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014Network 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 ...

On sensor network lifetime and data distortion
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005Fidelity is one of the key considerations in data collection schemes for sensor networks. A second important consideration is the energy expense of achieving that fidelity. Data from multiple correlated sensors is collected over multi-hop routes and fused to reproduce the phenomenon.

Maximization the lifetime of wireless sensor networks
2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA), 2015The technological developments in microelectronics have enabled the integration of capacity for realization of several important tasks for monitoring the environment in very small sensor named components with low cost and low power consumption. A sensor node detects environmental phenomenon to obtain data and transmits them to the sink via a single hop

Revisiting the lifetime of wireless sensor networks
Proceedings of the 2nd international conference on Embedded networked sensor systems, 2004Prolonging the lifetime of wireless sensor networks (WSN) is one of the most important goals in the sensor network research. A lot of work has been done to achieve this goal; however, current definition of lifetime is either superficial or impractical.
