Resources are scarce in Wireless Sensor Networks (WSN) and one of the challenges is to design a lightweight communication protocol to support efficient and uniform power consumption among nodes. In this paper, we propose an energy aware routing scheme based on a cross-layer approach for WSNs with the objective to minimize the overall consumed energy; thus,(More)
Media access control (MAC) protocols for mobile ad-hoc networks are of interest in applications ranging from wireless local area networks (WLANs) to global skywave highfrequency radio networks. Much of the recent work in wireless MAC protocols has emphasized networks with short turnaround times (e.g., IEEE 802.11 WLANs). However, some wireless networks(More)
The integration of wireless networking technologies with medical information systems (telemedicine) have a significant impact on healthcare services provided to our society. Applications of telemedicine range from personalized medicine to affordable healthcare for underserved population. Though wireless technologies and medical informatics are individually(More)
A sensor net consists of tiny devices with severe energy constraints. Employing energy efficient, sensor-specific MAC protocols is of necessity for sensor nets, and such protocols have been proposed in the literature. Sensor MAC protocols introduces sleep in sensor nodes to conserve energy and the impact of sleep on protocol performance needs a detailed(More)
Information prioritization would be crucial for several emerging applications of wireless and sensor networks (WSNs) that require real-time event monitoring (disaster/intrusion monitoring, industrial automation, telemedicine). The current Quality-of-Service (QoS) literature for sensor applications is still premature, since most of the development efforts(More)
Efficient wireless-networked health monitoring re-quires integrated operation of multiple platforms. In-body medical sensors can network using low-range personal area communication standards, such as Zig-bee/802.15.4. The data collection and distribution back-haul requires long-range, high-data rate technolo-gies (WiFi), and finally a mobile communication(More)
The foray of wireless networks into time-sensitive applications demands support for emergency services, with guaranteed QoS bounds. The IEEE 802.11e technology could be an attractive option for emergency networking, if the protocol design is enhanced to achieve deterministic QoS for emergency traffic during distributed network operation. We propose Channel(More)
Abstract – One of the significant applications of Wireless Sensor Networks (WSNs) is threat surveillance, where events are rare and the sensing nodes are idle most of the time. Sleep is essential for conserving energy in such applications, since, for sensor technology, the energy consumption rate during idle state is in the same order of magnitude as during(More)
Distributed Wireless Sensor Networks (WSNs) operate under severe energy constraints and are largely characterized by short-range multi-hop radio communications, which signify the role of energy-efficient routing schemes for such networks. Fuzzy Diffusion, an energy optimization on the general diffusion schemes for application-aware sensor networks, has been(More)
