Sensor networks is an interdisciplinary research area that draws on contributions from signal processing, wireless networking and associated routing protocols, database management and information systems, distributed algorithms and MEMS technology. Recent developments in Wireless Sensor Networks have resulted in wide variety of realtime applications. Many(More)
One of the most important and challenging issues in wireless sensor networks (WSNs) is to optimally manage the limited energy of nodes without degrading the routing efficiency. In this paper, we propose an energy-efficient adaptive routing mechanism for WSNs, which saves energy of nodes by removing the much delayed packets without degrading the real-time(More)
Reliability, Power efficiency and timeliness are the critical issues in Wireless Sensor Networks (WSNs). The engineers must fulfill the QoS requirements imposed by the applications(users).To satisfy QoS metrics such as Reliability, timeliness and energy efficiency, these WSNs must overcome major obstacles such as dynamic environmental changes, limited(More)
