There is large change in the utilization of wireless sensor network over the last few years. A Wireless sensor network essentially consists of a group of nodes deployed for monitoring the system via means of measurement of its parameters. WSN mostly consist of two terms i.e. wireless network and sensors. Wireless Sensor is a significant technology designed for large-scale monitoring, providing sensor...
Optimization Wireless Sensor Network (WSN) is necessary to reduce redundancy and energy consumption. To optimizing wireless sensor networks for secured data transmission both at cluster head and base station data aggregation is needed. Data aggregation is performed in every router while forwarding data. The life time of sensor network reduces because of employing energy inefficient nodes for data...
Wireless Sensor networks are non-infrastructure networks which consist of mobile sensor nodes. Since the mobile nodes have limited battery power, it is very important to use energy efficiently in sensor networks. In order to maximize the lifetime of sensor networks, traffic should be sent via a route that can avoid nodes with low energy thereby minimizing the total transmission power. In addition,...
Wireless Sensor Networks (WSN) consist of spatially distributed sensor to monitor physical or environmental conditions and cooperatively pass their data to a central location. Such networks become importance due to its potential to transform many segments of our life from ecological monitoring and maintenance to computerization in traffic surveillance and healthcare commerce. The design, implementation...
Wireless sensor networks consist of spatially distributed sensor to monitor physical or environmental conditions and cooperatively pass their data to a central location. These kinds of network have come into prominence because they hold the potential to revolutionize many segments of our life from environmental monitoring and conservation to automation in traffic monitoring and health-care business...
The sensors in sensor networks have limited energy and thus energy preserving techniques are important but in many cases like war zone the time for complete a task is more important than energy and in large-scale sensor networks, redundant communication between sensor nodes is necessary to propagate data in a large monitoring region. The main objective of this paper is to efficiently disseminate information...
Wireless sensor networks are widely used in different fields. Because of its distinguished characteristics, we must take account of a factor of energy consumed when designing routing protocol. The routing protocols of the wireless sensor networks have mainly two types: flat routing protocol such as directed diffusion and SPIN, and hierarchical routing protocol such as LEACH and its variations. In...
A wireless sensor network refers to a group of sensors, or nodes/bluetooth, linked by a wireless medium to perform distributed sensing tasks. Traditional routing protocols developed for wireless ad hoc networks cannot be used for sensor. This is because conventional protocols focus on avoiding congestion or maintaining connectivity when faced with mobility and not on the limited energy supply. We...
