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 performance of the used routing protocol...

The geographic routing technology is good for the self-organizing and large-scale Wireless Sensor Networks(WSNs), and the energy-limited sensor nodes require the energy used for routing to be minimum. In this paper a new energy-efficient geographic routing algorithm is proposed and it is distributed and based on the geographic routing, the topology characteristics of the network and the wireles...

Wireless Sensor Networks (WSNs) have become one of the most prominent areas of research in the field of modern communication systems. But unlike IP based routing, WSNs focus on data centric communication. Thus routing is one of the important issues to be considered for a wireless network. As sensor networks are generally deployed in hostile environments, batteries cannot be recharged often. Thu...

Energy is the vital resource in the life of a wireless sensor node. So, its usage must be optimized to extend the network life. Routing protocols should also be concerned about the overhead energy which is wasted at each hop during data transfer. Main feature of routing protocol, I n order to be efficient wireless sensor networks, is the energy consumption and the extension of the network’s lif...

Routing Optimization in mobile ad hoc networks is an ever-demanding task. Mobile ad hoc networks are highly dynamic topology natured and hence several routing protocols meet the challenge of link quality, delay and energy conscious routing. This paper proposes a link quality, delay and energy conscious routing approach based on ant colony optimization. Based on the estimated link quality, delay...
