The Expected Uncertainty of Range Free Localization Protocols in Sensor Networks
We consider three range-free localization protocols for sensor networks and analyze their accuracy in terms of the expected area of uncertainty of position per sensor. Assuming a ...

Distributed localization using noisy distance and angle information
Localization is an important and extensively studied problem in ad-hoc wireless sensor networks. Given the connectivity graph of the sensor nodes, along with additional local info...

Coordinated Robust Routing by Dual Cluster Heads in Layered Wireless Sensor Networks
In this paper, we propose the coordinated robust routing (CRR) scheme to address the fault tolerance requirements in the layered wireless sensor networks. In the proposed scheme, ...

Integrated distributed energy awareness for wireless sensor networks
Energy in sensor networks is a distributed, non-transferable resource. Over time, differences in energy availability are likely to arise. Protocols like routing trees may concent...

Transmission Schemes for Lifetime Maximization in Wireless Sensor Networks: Uncorrelated Source Observations
Abstract— We study transmission schemes for lifetime maximization in wireless sensor networks. Specifically we consider the network where all the sensors observe uncorrelated si...
