We propose and evaluate wireless sensor routing algorithms designed to extend the lifetime of a heterogeneous wireless sensor network. The network is heterogeneous in the sensorsā...
āIn sensor networks, both energy and bandwidth are scarce resources. In the past, many energy efļ¬cient routing algorithms have been devised in order to maximize network lifetim...
During the last decade, many works were devoted to improving the performance of relaying techniques in ad hoc networks. One promising approach consists in allowing the relay nodes ...

The problem of optimal data gathering in wireless sensor networks (WSNs) is addressed by means of optimization techniques. The goal of this work is to lay the foundations to devel...
We define a transmission power adaptation-based routing technique that finds optimal paths for minimum energy reliable data transfer in multi-hop wireless networks. This optimal ch...
