Radio Frequency (RF) Energy Harvesting holds a promising future for generating a small amount of electrical power to drive partial circuits in wirelessly communicating electronics devices. Reducing power consumption has become a major challenge in wireless sensor networks. As a vital factor affecting system cost and lifetime, energy consumption in wireless(More)
Improving network lifetime and reliability are the fundamental challenges in Wireless Sensor Networks (WSNs). The main issue in events sensing and relaying in WSN is the formation of energy-holes near the sink. Nodes near the sink are more likely to use up their energy because they have to forward all the traffic generated by the nodes farther away to the(More)
This research focuses on detection of unauthorized access to residential and commercial buildings when the residents are far away from the access gate of the house. The system is a simple and reliable touch activated security system and uses sensor technology to revolutionize the standards of living. The system provides a best solution to most of the(More)
High efficient routing is an important issue in the design of limited energy resource Wireless Sensor Networks (WSNs). Due to the characteristic of the environment at which the sensor node is to operate, coupled with severe resources; on-board energy, transmission power, processing capability, and storage limitations, prompt for careful resource management(More)
Termites present a very good natural metaphor to evolutionary computation. While each individual's computational power is small compared to more evolved species, it is the power of their colonies that inspires communication engineers. This paper presents a study of artificial termites in sensor networks for the purpose of solving its' routing problem. The(More)
