Geocast for wireless sensor networks
2011 19th IEEE International Conference on Network Protocols, 2011An important but relatively less studied class of network layer protocol for sensor networks is geocast. It allows a sensor node to send messages to all nodes in a given geographical area without the sender node having any knowledge about which nodes are present in that area.

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.

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

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.

Wireless Temperature Sensor System
International Conference on Networking, International Conference on Systems and International Conference on Mobile Communications and Learning Technologies (ICNICONSMCL'06), 2006Knowledge of temperature course during a certain time is needed in scientific, medical and industrial applications. In some applications, however, the recorded temperature course should be read wirelessly. This paper describes main principles applied in a set of mobile temperature data logger and portable interrogator with wireless transfer of ...

A language for wireless sensor webs
Proceedings. Second Annual Conference on Communication Networks and Services Research, 2004., 2004A language for wireless sensor webs called the sensor web language (SWL) is presented. SWL is especially useful for transmitting information over low power wireless networks with relatively low bandwidth. The language has been designed for automated translation into three software layers.

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
