Current advances in wireless sensor networks have contributed to the development of multi-hop wireless body sensor networks (WBSNs). These networks, which are primarily comprised of low-power sensor nodes, provide long term health and physiological monitoring of patients without obstructing their normal activities. However, the time-varying nature of network resources poses a significant challe...

This work describes the implementation of a complete wireless body-area network (WBAN) system to deploy in medical environments. Issues related to hardware implementations, software and wireless protocol designs are addressed. In addition to reviewing and discussing the current attempts in wireless body area network technology, aWBAN system that has been designed for healthcare applicationswill...

Routing protocol for wireless mobile sensor networks can be active, can also be passive. The network all wireless sensor node is base station and the gateway for two-way communication. To complete the training parameters, which can be called the training function is used to train the BP neural network. The paper presents design and implementation of wireless sensor network nodes based on BP neu...

This paper introduced about the data aggregation in wireless sensor network. We have presented SOM Based Data Aggregation Algorithm in Neural Network based Multihop Wireless Sensor Network and AdWAS: Adaptive Weighted Aggregation Scheme for Single-hop and Multi-hop Wireless Sensor Network.

Sensor networks are gaining importance as they have vast potential for diverse application areas like monitoring, localizing and tracking of environmental phenomenon. The sensors are constrained by extremely scarce resources, unreliable communication link and faulty nodes. There is a need to address these harsh operating conditions. Real time sensitive applications which require fault free obse...

Wireless sensor networks (WSNs) consist of a large number of sensor nodes which are capable of sensing different environmental phenomena and sending the collected data to the base station or Sink. Since sensor nodes are made of cheap components and are deployed in remote and uncontrolled environments, they are prone to failure; thus, maintaining a network with its proper functions even when und...

Rowing is an intensive, all-body sport, where bad technique can lead to injury. Crew cohesion, particularly timing, is vital to the performance of the boat. The coaching process, and injury prevention, could be enhanced if data relating to the movement of the oarsmen could be collected, without hindrance to the oarsmen, during on-water training. Literature until recently has concentrated upon b...

A mobile ad hoc network is comprised of mobile hosts that can communicate with each other using wireless links. It is also possible to have access to some host in a fixed infrastructure depending on the kind of the mobile ad hoc network. Mobile ad hoc networks can be realized by different networks such as body area network (BAN), vehicular ad hoc network (VANET), wireless sensor network (WSN). ...

In wireless sensor network, traditional security mechanisms such as cryptographic methods need a large consumption of resources such as memory, speed, and communication bandwidth. And by using such techniques it is not possible to detect malicious, faulty and selfish nodes that harm to network. Alternatively, trust methods calculate trust of sensor nodes and thereby help to detect malicious, se...

Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...
