This research work provides a method for forming a communications link of Wireless Sensor Networks (WSN) by enabling each WSN to act as a smart antenna. Each WSN is simulated as a set of randomly placed sensor nodes within a planar area. The proposed method involves a searching WSN, a receiving WSN and a link budget for establishing the link. The searching WSN has the task of transmitting a sea...

a wireless sensor network (wsn) is a wireless decentralized structure network consists of many nodes. nodes can be fixed or mobile. wsn applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in wsn. wireless localization used to determine the position of nodes. the precise localization in wsns is a co...

Tracking multiple targets in an energy efficient way is an important challenge in wireless sensor networks (WSNs). While most of the prior work consider tracking multiple targets as execution of single target tracking algorithms multiple times and utilize only single parameters for efficient energy consumption, we identify multiple parameters that can influence the energy efficiency of sensors ...

Deployment, coverage and energy efficiency are the main goals set in wireless sensor network. The network constituted by the small sensor nodes having the three main tasks of sensing, data processing and forwarding with the aim to reach base station. The base station works as the sink for the data which is generated by the sensor nodes in case of wireless sensor networks. The sensor networks ha...

AbstractIn the present work we introduce an integrated approach for structured design of Wireless Sensor Networks (WSNs) that enables step-by-step design, optimization, and flexibility in choosing the trade-offs. Founded on the knowledge accumulated by the WSN community, our approach merges the recent advances in optimization of the multitude of WSN dimensions in one complete design strategy. A...

Wireless Sensor Network (WSN) are the network of sensor nodes which communicate with each other and with the base station using wireless channel. Due to extensive use of wireless sensor networks it is necessary to improve its security. WSN nodes are prone to physical attacks. Wireless sensor networks (WSN) face security threats so traditional key management schemes are no longer accurate for WS...

A WSN is composed of a large number of sensor nodes that are communicating using a wireless medium. The sensor nodes are deployed in the environment to be monitored in ad hoc structure. In WSN, there is sink node that collects data from all sensors, and usually not all nodes hear all other nodes. WSN is considered a multi-hop network. Although a WSN is a wireless multi-hop network, the ease of ...

Various enhancements have been provided for wireless sensor network (WSN) to increase the capability and availability of the small and cheap nodes in WSN. One of the most important features of WSN is the ability of sending and receiving the data effectively. There are several limitations of WSN like, transmission range, storage, lifetime, and energy resources. Routing in WSN came to ensure reli...

After earthquakes, qualified inspectors typically conduct a semisystematic information gathering, physical inspection, and visual examination of the nation’s public facilities, buildings, structures. Manual examinations, however, take lot time frequently demand too much work. In addition, there are not enough professionals to assess such structural damage. As result, in this paper, efficiency c...
