Improving network lifetime is the fundamental challenge of wireless sensor networks. One possible solution consists in making use of mobile sinks. Sink mobility along a constrained path can improve the energy efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly...
The function of the nodes in Wireless Sensor Networks which are connected via wireless links are sensing the events when placed in the environment and sending those sensed data to the base station. Routing, power management, and data dissemination protocols have been employed for WSN. In WSN where nodes are mobile and communicate directly to base station like MANET (Mobile Ad-hoc Network), the Proactive...
Wireless sensor networks are mainly designed for environment monitoring. The lifetime of wireless sensor networks depends on the durability of the battery resource sensors, so it is crucial for sensors to efficiently use their limited battery resources. The energy expends by sensors in data communication makes up a significant quantum of their total amount of energy consumption. In the existing research,...
A Wireless Sensor Network (WSN) consists of a large number of small sensors with limited battery power. Prolonged network lifetime, scalability, node mobility and load balancing are important requirements for many WSN applications.

Through efficient clustering of WSN we...
The advances in the area of the micro-electro-mechanical systems (MEMS) technology provides to send the data without any physical connection from Wireless Sensor Node (WSN) to the Base Station, this data may be modified by an attacker or dropped, if no security is provided. There is various secured routing protocol to resist the attacks.
Ubiquitous computing provides access to information and computing resources for the users in the place where they are, anywhere and anytime. In Ubiquitous Computing, every applications uses Context awareness as the most important properties. In particular, for smart bank, context awareness attempts to bring the best services to the bank customers. Since bank is the place where most of the people have...
Wireless sensor networks are of a large number of low cost resource constrained sensor nodes.

The proposed system utilizes the concept of multi hop communication in Wireless Sensor Networks (WSNs). On the other hand, the single hop communication leads to more power dissipation in the nodes at the time of transmitting sensed data. The proposed system rectifies the above mentioned problem with the multi hop communication among the finite number of nodes to determine the distance for transferring...

In nonuniform sampling based Compressed Sensing the DCT coefficients of an image block are scanned in zigzag order to form a single column vector. This column vector is divided into important and unimportant component. If same measurement matrix is used to measure the unimportant component of all blocks of an image, it results in large number of measurements. In this paper, a two measurement matrix...
The major issue in wireless sensor network (WSN) is the power control since it is impossible to recharge or replace the batteries of the sensors. The sensors transmit at high power to make its transmission successful. Transmitting at high power not only reduces the lifetime of the nodes and that of the network, it also introduces excessive interference. Therefore, every node should transmit at minimal...
