In wireless sensor networks (WSNs)‎, ‎sensor nodes have limited resources with regard to computation‎, ‎storage‎, ‎communication bandwidth‎, ‎and the most important of all‎, ‎energy supply‎. ‎In addition‎, ‎in many applications of sensor networks‎, ‎we need to send images to a sink node‎. ‎Therefore‎, ‎we have to use methods for sending images in which the number and volume of packets are optim...

wireless sensor networks are the new generation of networks that typically are formed great numbers of nodes and the communications of these nodes are done as wireless. the main goal of these networks is collecting data from neighboring environment of network sensors. since the sensor nodes are battery operated and there is no possibility of charging or replacing the batteries, the lifetime of ...

Recent advances in wireless sensor networks have provided many opportunities for researchers on wireless networks around the body such as Body Area Network (BAN) or Body Sensor Network (BSN). A BSN allows health monitoring of patients whereby caregivers receive feedback from them without disrupting their normal activities. This monitoring requires the employment of the low-power sensor nodes im...

Wireless Body Area Network is an Emerging field in the branch of Wireless Sensor Network for research due to its various applications in healthcare, entertainment, defense etc. In Body Area Network, sensors monitor the human’s activities and actions like their health parameters so it is necessary to secure the privacy of the user and the medical information collected by the sensors from the bod...

In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...

Wireless sensor networks are rapidly growing as they have many outstanding characteristics such as the low power consumption, remote location sensing, low cost wirelessly communication and mobility. There has been increase in using wireless sensor networks in the biomedical and healthcare. However, using wireless sensor network introduce new challenges that are related to privacy and security. ...

Unlike existing wireless sensor network (WSN) environments, wireless body sensor network (WBSN) environments can have dynamic channel characteristics depending on sensor placements, human movements, and surrounding environments. In this study, to analyze such WBSN channels, the stomach, back, forearm, wrist, thigh, and ankle were set as sensor placements and standing, walking, and running were ...
