Using Wireless Sensor Networks (WSNs) in health care system has yielded a tremendous effort in recent years. However, in most of these researches tasks like sensor data processing, health states decision making and Continue reading
This study introduces a new approach of parking system by using Wireless Sensor Network (WSN) technology equipped with ultrasonic sensors. The system also implements shortest path algorithm to calculate the shortest distance from the parking berth to the nearest Continue reading
Voice over IP (VoIP) can be defined as the ability to make phone calls and to send faxes (i.e., to do everything we can do today with the Continue reading
The goal of the project is to design the star-based mesh topology by introducing multiple pan-coordinators (hub/switches) under a multipath-fading environment and to improve the Continue reading
Ad hoc based routing protocol is a reactive protocol to route messages between mobile nodes. It allows nodes to pass messages through their neighbors to nodes which they Continue reading
Short range wireless data communication networks that are used for sport and health care are sometimes called Wireless Body Area Networks (WBANs) and they are located more or less on a person. Sole Integrated Gait Sensor (SIGS) is a research project in Continue reading
Retrieving data from a patient in real-time is a challenging operation, especially when requiring information from the network to support the patient’s health. A real-time healthcare system process is conducted with a continual input, processing, and Continue reading
To implement a utility wireless sensor network, investigation of different wireless protocols has been performed. The protocols are Bluetooth, Wi-Fi, IEEE 802.15.4 and Continue reading
Sensor networks are commonly used for security and surveillance applications. As sensor nodes have limited battery power, computing, and storage resources, the energy efficient security techniques are needed.
We provide a new heuristic approach to search for balanced and small weight routing spanning trees in a network. The approach is Continue reading
Virtual multiple input multiple output (MIMO) techniques are used for energy efficient communication in wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing based on virtual MIMO. The simulation results show that virtual MIMO based routing is more energy efficient as compared to SISO (single input single output) for larger distances.
In recent years, virtual MIMO has attracted a growing interest because of its energy efficiency in large field of networks. In virtual MIMO network, a group of sensors cooperate Continue reading
Recently, there has been a growing interest in the potential use of Wireless Sensor Networks (WSNs) in many applications such as smart environments, disaster management, combat field reconnaissance, and security surveillance. Therefore, to realize their potential, there is a need of an architecture that facilities the deployment of a network that is optimized in terms of energy, query and network configuration.
This paper focuses on developing agent-based peer-to-peer layered system architecture for Continue reading
