In recent years, energy efficiency and data gathering is a major concern in many applications of Wireless Sensor Networks (WSNs). One of the important issues in WSNs is how to save the energy consumption for prolonging the network lifetime. For this purpo... see more

Limited battery power directly affects the performance and survival time of sensor networks. In this study, solar energy was used to provide additional energy for sensor nodes, and a clustering algorithm for heterogeneous wireless sensor networks (WSNs) b... see more

In order to optimize the network architecture, addressing mechanism, heterogeneous nodes and other functions of wireless sensor networks, this study begins with the issue of networking of large-scale heterogeneous networks. A layered distributed network a... see more

Sensor networks are being used to implement different types of sophisticated emerging applications, such as those aimed at supporting ambient intelligence and surveillance systems. This usage is enhanced by employing sensors with different characteristics... see more

The data aggregation is a widely used mechanism in Wireless Sensor Networks (WSNs) to increase lifetime of a sensor node, send robust information by avoiding redundant data transmission to the base station. The privacy preserving data aggregation is a cha... see more

Home Area Networks designed for the delivery of both multimedia contents (e.g. TV programs, movies, music) and home automation services (e.g. household appliances commands, lighting and surveillance controls) are becoming widespread, especially thanks to ... see more

Wireless Sensor Network (WSN) is a combination of homogeneous andheterogeneous sensor nodes which are physically deployed at different places. HeterogeneousWSM can be characterized with different parameters such as hardwareresources, application, services... see more

Congestion control and energy consumption in Wireless Multimedia Sensor Network is a new research subject which has been ushered in through the introduction of multimedia sensor nodes that are capable of transmitting large volume of high bit rate heteroge... see more

Due to the sensibility of power issue in wireless sensor networks and the limitations of power sources, preserving energy issue prepossess most recent advances researches in this field. Routing protocols have considerable space in those researches, and th... see more
