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

Security in wireless sensor networks
IEEE Wireless Communications, 2008Recent advances in electronics and wireless communication technologies have enabled the development of large-scale wireless sensor networks that consist of many low-power, low-cost, and small-size sensor nodes. Sensor networks hold the promise of facilitating large-scale and real-time data processing in complex environments.

Adaptability in wireless sensor networks
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008Adaptability is a key strategy in the design of effective wireless sensor networks. Communication schemes need to adapt to dynamic topologies and fluctuating traffic rates. Applications have to alter their behavior to respond to mutated necessities or to cope with environmental changes.

Security of Wireless Sensor Networks
2011 Eighth International Conference on Information Technology: New Generations, 2011Wireless sensor networks have been researched extensively over the past few years. They were first used by the military for surveillance purposes and have since expanded into industrial and civilian uses such as weather, pollution, traffic control, and healthcare.

On the Security of Wireless Sensor Networks
2005Wireless Sensor Networks are extremely vulnerable against any kind of internal or external attacks, due to several factors such as resource-constrained nodes and lack of tamper-resistant packages. As a result, security must be an important factor to have in mind when designing the infrastructure and protocols of sensor networks. In this paper we survey

Evolution of Wireless Sensor Network
2007 IEEE Wireless Communications and Networking Conference, 2007Topology control for fault tolerant communication is one of the important issues in wireless sensor networks. This paper presents a simple mechanism of fault tolerant topology control for generating undirected scale-free networks, where the network evolution is determined by the rules of growth and preferential attachment.

Environmental Wireless Sensor Networks
Proceedings of the IEEE, 2010This paper is concerned with the application of wireless sensor network (WSN) technology to long-duration and large-scale environmental monitoring. The holy grail is a system that can be deployed and operated by domain specialists not engineers, but this remains some distance into the future.

On modeling wireless sensor networks
18th International Parallel and Distributed Processing Symposium, 2004. Proceedings., 2004Summary form only given. Most of the current research in wireless sensor networks (WSN, for short) is constraint driven and focuses on optimizing the use of limited resources (for example, power) at each sensor. While such constraints are important, there is a need for more general performance metrics describing the effectiveness of WSNs. There is also

Underground wireless sensor networks
2009 IEEE 10th Annual Wireless and Microwave Technology Conference, 2009In this paper the possibility to construct wireless sensor networks buried in the terrain is discussed. Advantages and drawbacks are pointed out, and an analysis of the most efficient method to evaluate the effect of radio-link parameters on radio propagation is provided.

Architectures for Wireless Sensor Networks
2005 International Conference on Intelligent Sensors, Sensor Networks and Information Processing, 2005The vision of ubiquitous computing requires the development of devices and technologies that can be pervasive without being intrusive. The basic component of such a smart environment will be a small node with sensing and wireless communications capabilities, able to organize itself flexibly into a network for data collection and delivery. Building such
