Abstract: In Wireless Sensor Network (WSN) the sensor nodes are very much sensitive to the energy consumption. The success of the wireless sensor network applications highly depends on the reliable communication among the sensor nodes. One of the major problems in WSN environments is the limitation of the physical resource that is energy resources. More energy is consumed in transmitting and re...
The deterministic energy efficient protocol for adjustable sensing range (ADEEPS) is one of the important protocols for enhancing the lifetime of a wireless sensor network. This protocol however considers the underlying network of homogeneous nature. In this paper, we propose hetADEEPS (heterogeneous ADEEPS) protocol that considers the underlying network of heterogeneous nature. The heterogeneo...
Heterogeneous wireless sensor networks such as High Performance Wireless Research and Education Network (HPWREN) have environmental sensors located in remote and hard-to-reach locations far from the main high-bandwidth data links. The sensed data needs to be routed through multiple hops before reaching the backbone. The routing is done by battery-powered nodes using license free radios such as ...
Wireless sensor networks consist of many small nodes. Each node has a microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. Since the nodes are battery powered and communication consumes more power th...
Wireless sensor networks (WSNs) contain multiple nodes of the same configuration and type. The biggest challenge nowadays is to communicate with heterogeneous nodes of different WSNs. To communicate with distinct networks, an application requires generic middleware. This middleware should be able to translate the requests for contrary WSNs. Most of the wireless nodes use the TinyOS or Contiki o...
In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accuracy and cost, in order to study the Earth's surface. One of the most important challenges in this area, is the signaling network coverage and finding holes. In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accurac...
Wireless sensor networks have many applications in the real world and have been developed in various environments. But the limitations of these networks, including the limitations on the energy and processing power of the sensors, have posed many challenges to researchers. One of the major challenges is the security of these networks, and in particular the issue of authentication in the wireles...
