Wireless body sensor networks (WBSN), elected as a promising infrastructure for mobile health (m-health) applications and e-healthcare, are facing many challenges related to their powering and processing capabilities. In depth, the available hardware resources and energy embedded on these tiny body sensors, to record and transmit continuous streams of unprocessed biosignals, are limited and cannot...
In this paper the entire area is divided into clusters. Each of the clusters has a set of nodes which are spread randomly across the clusters. Cluster Head Election algorithm LEACH elects a different cluster heading each round. LEACH routing algorithm is also simulated for sending the packets for inter cluster communication and intra cluster communication between source node and destination node....
Many physical devices and sensors make it possible to obtain more localized data and applications which provide more localized information for users will appear. Generally, those applications use a storage server for computing location-dependent data. Traffic of Internet of Things (IoT) devices may cause concentration, when data is stored into a server. It is desirable that each location-dependent...
The Internet of Things (IoT) is being applied in a wide variety of applications, which demand a range of networking support. This includes wide area communication networks. Novel long range network technologies such as LoRa and Sigfox are emerging, but they remain difficult to deploy and configure for end-users who are not specialists in embedded systems. This paper addresses this problem by introducing...
Bus transports in the cities of many developing countries are marred with severe problems, like information unavailability, bad road and bus conditions, lack of proper scheduling and timing, and so on. An information service can become extremely handy for the travelers in countries with emerging economy, where public traffic systems are generally riddled with uncertainty. We have developed CrowdMap...
Wireless sensors are used to acquire the data from different environments such civilian applications, military, tracking, seismic measurements and monitoring applications in order to take necessary actions or to prevent the disasters, to do so all sensors consumes more energy. Since, the sensor is a battery operated device the lifetime of each sensor is reduced. Therefore effective cluster formation...
Wireless acuusuc sensor networks (wasns) are a promising technology for performing acoustic surveillance because of their flexibility and low cost. However, their commercialization is nowadays limited due to their high energy consumption, which is mainly a result of the high data rates required to stream audio data between sensor nodes. In order to improve energy efficiency in WASNs, we explore the...
Despite of continuous evolution of Wireless Sensor Networks, Energy exhaustion issue of wireless sensors is still remained. Thus, it is difficult to guarantee the self-sustainability of each sensor. Researchers in areas of energy conservation and energy harvesting have been consecutively developing new methods to increase the lifetime of a sensor. One of the methods is the Adaptive Sampling Algorithm...

Generally the data sensed by the sensors are collected and routed to the sink in a specific manner for further processing. In this proposed work, the sink node is dynamic rather than being mobile. The dynamic sink collects the data from the pervasive environment continuously. The dynamic route (path) to the sink is established, maintained and updated. Finally the comparison is made between the mobile...
The proposed work aims at designing routing method and data compression algorithm for WSN's. An ad-hoc network (WANET) is considered and based on certain criteria the data is forwarded dynamically. Various parameters such as Compression Ratio, Packet Delivery Rate, Energy consumption are considered to determine the efficiency of the network. One of the primary parameters to be considered in the configuration...

Radio frequency (RF) recharging can extend maintenance-free operation of wireless sensor networks. However, the period between recharging is limited by the distance between the most distant sensor node and the master which sends out recharging pulses. To increase this period, we propose a scheme in which nodes are logically grouped into circular zones centered at the master, so that nodes in a given...
Networks of unmanned aerial vehicles (UAVs), capable of providing flexible aerial views over large areas, are playing important roles in today's distributed sensing systems. Since camera sensors are sensitive to occlusions, it is more challenging to deploy UAVs for sensing in geometrically complex environments, such as dense urban areas and mountainous terrains. This paper proposes a new occlusion-aware...
Energy efficiency has become a main challenge in Wireless Sensor Networks (WSNs) and their applications. Localization is one of the indispensable stages in WSN.
