Abstract Recent convergence of information communications technology and computing is creating new demands and opportunities for ubiquitous computing via wireless and mobile equipments. The demanding networking environment of wireless communications and the fast-growing number of mobile users impose several challenges in terms of channel estimation, network protocol design, resource management, systematic design, application development, and security.

In this paper, we investigate how to design greedy routing to achieve sustainable and scalable in a large-scale three-dimensional (3D) sensor network. Several 3D position-based routing protocols were proposed to seek either delivery guarantee or energy-efficiency in 3D wireless networks. However, recent results [1, 2] showed that there is no deterministic localized routing algorithm that guarantees either delivery of packets or energy-efficiency of its routes in 3D networks.

Abstract Energy efficient routing and power control techniques in wireless ad hoc networks have drawn considerable research interests recently. In this paper, we address the problem of energy efficient reliable routing for wireless ad hoc networks in the presence of unreliable communication links or devices or lossy wireless link layers by integrating the power control techniques into the energy efficient routing.
