In today's smart world, the privacy protection of data is an important issue. Data distributed, reproduced, and disclosed with extensive use communication technologies. Many non-traditional challenges arise rapid increase IoT devices for system design implementation. However, security are main issues in IoT. With advanced technologies, illegal copy content can easily be generated shared. Theref...

Data aggregation plays an important role to improve the transmission efficiency in wireless body area networks (WBANs); however, it inherently induces additional aggregation delay. Therefore, the effect of packet aggregation on WBAN applications, which are vulnerable to delay, must be analyzed rigorously. In this paper, we analyze the packet aggregation delay for multisource sensor data with an...

Wireless Sensor Networks is a fast leading technology which has showed up many opportunities in the field of data reporting and monitoring. It has a collection of sensor nodes which can report data to the base station. It increases energy consumption and traffic. So to avoid network traffic and to prolong network lifetime clustering scheme is used. Mobile sinks can easily move to the deployed a...

However, primarily due to the severe constraints and secondarily due to the inherent increased costs in communications relative to that in processing, the WSNs follow in-network processing, wherein the emphasis is on on-thefly processing of the data packets before being communicated eventually to the base station [3]. The processing typically consists of the data aggregation operations like sum...

Sensor networks are currently an active research area mainly due to the potential of their applications. In this paper we investigate the use of Wireless Sensor Networks (WSN) for air pollution monitoring in Mauritius. With the fast growing industrial activities on the island, the problem of air pollution is becoming a major concern for the health of the population. We proposed an innovative sy...

Now days , interests in the application of Wireless Body Area Network (WBAN) have grown considerably. A number of tiny wireless sensors, strategically placed on the human body, create a wireless body area network that can monitor various vital signs, providing real-time feedback to the user and medical personnel. This communication needs to be energy efficient and highly reliable while keeping ...

In this paper, we focus on monitoring environments with wireless sensor networks in which mobile sink nodes traverse sensing fields in a specific spatialtemporal manner and aggregate various types of environmental data with different deadline constraints distributed over sensor nodes. For such environments, we propose an energy-efficient data aggregation method that reduces intermediate transmi...
