Wireless sensor network (WSN) is a collection of large number of self-organized types of sensors which chain together to monitor and record physical or environmental conditions (i.e. used to measure temperature, sound, pressure) and passes gathered information to the central location. WSN build bridge between real world and virtual environment, which makes it more utilizable for many applications...
A versatile framework for automation of sophisticated farm machinery has been proposed in this paper. The paper details the functional design and development of the hardware and software architecture of the framework for electronic monitoring and control of a complex system. The framework aims to provide a user friendly bridge between the digital world and the physical world and covers the core software...
Energy efficient data collection is the major challenging task in the Wireless Sensor Network(WSN). Since, batteries are the main power sources of sensor nodes which has limited energy. In multi hop clustering, Base Station's neibourhood nodes have overload compare to far nodes because nearer nodes transmit their own data as well as other nodes data. As a result, the Base Station (BS) nearby nodes...
WSN is a network in which sensors are distributed randomly in space to keep track of any environmental or physical conditions. The uses of WSN is innumerable. Energy conservation and enhancing network lifetime are always been a challenging task.

There are many applications for which location information plays a crucial role. Finding location information by a sensor node is called the localization problem. The major challenge is to determine the location of unknown nodes based on the known location of other nodes. In this paper, a range-free localization scheme based on fuzzy-logic approach has been proposed. The localization scheme uses the...
While using Wireless Sensor Network for monitoring the remote patient's health situations, data related to that patient is stored in the sensors and the huge amount of data results in buffer and link overflow. The buffer and link overflow causes the problem of congestion which results in loss of packet and transmission delay. Congestion is a situation in which buffer overloaded with excessive data,...

Wireless sensor network (WSN) is very important these days. It is used frequently in many applications in the area such as health care, security, home and military. As the sensor nodes in the domain may change over the time due to number of factors such as environment condition, lifetime of the battery (low battery power) and coverage (area of interest), then a sensor network needs periodically to...
Concentration of Carbon monoxide (CO) and Carbon dioxide (CO2) that high in the air is very dangerous for human life. Carbon monoxide is a poisonous gas that damages the circulation of oxygen in the blood when inhaled, while carbon dioxide is one of the gases that cause global warming. Both gases are classified as colorless and odorless gas so that the necessary special tools to monitor their concentration...
Most of researches about the design of the topology and the operation of a wireless sensor network are focusing on how to take advantage of all sensor nodes to collect information that covering the whole sense area.
