In Vehicular Ad-hoc network (VANETs) the communication is performed on the roads among the vehicles. There are many proposed localization algorithms for VANETs. Some are based on global positioning system (GPS) and others are not GPS based. The common problem with all the available algorithms is non-continuous availability i.e. Not available in the tunnel or in the busy area where heavy traffic. Therefore...
Wireless Sensor Networks (WSNs) are designed for supporting applications in long-term deployments. However, the researchers have recently explored many new WSN systems. To address the issue of noise presence in real time scenarios, a noise-measuring system based on WSN is presented in this paper. It can be used to collect data at unattended measuring-points, and transmit it to the data center. After...
For the design of a network layer routing scheme for Underwater Wireless Sensor Network (UWSN), physical layer cooperation is used in this paper which ensures energy efficiency. For achieving major goal of efficient data routing, a key factor is reliability for application-oriented UWSNs. All the nodes of network fortified by a unidirectional antenna cooperatively perform their propagation of data...
Provisioning buffer management mechanism is especially crucial in resource-constrained delay tolerant networks (DTNs) as maximum data delivery ratio with minimum overhead is expected in highly congested environments. However, most DTN protocols do not consider resource limitations (e.g., buffer, bandwidth) and hence, results in performance degradation. To strangle and mitigate the impact of frequent...
In the modern digital age the world became a global village. Finger tips availability of all government services is the goal of every government. That's why the governments of today's world are transforming their manual government services to electronic government services frequently. In the meantime the entire digitization of the system is prone to various security issues. Clear steps must be taken...
