Wireless Sensor Networks are a set of sensor nodes that probe their surroundings and send data over multi-hop routes to base-station (BS) for processing. Many routing protocols have been developed WSNs. A great attention has given geographic protocols, which rely only on local knowledge disseminate towards the BS. In this paper, we propose new energy efficient protocol called Improved Energy-aw...

Wireless sensor networks are expected to revolutionize our abilities in sensing and controlling the physical environment. Power conservation is a primary research concern for these networks, due to the limited energy resources of the sensor nodes. In this paper we study the data delivery approaches, suitable for hierarchical cluster based wireless sensor networks. A radio energy dissipation mod...
