Journal ArticleDOI
UWB wireless sensor networks: UWEN - a practical example
TL;DR: This article examines one example of a UWB sensor network for outdoor sport and lifestyle applications that has potentially low complexity and low cost, have noise-like signal, are resistant to severe multipath and jamming, and have very good time domain resolution allowing for location and tracking applications.
Journal ArticleDOI
Energy Optimization in Multihop Wireless Embedded and Sensor Networks
TL;DR: The results show that always using a simple multihop message relay strategy is not always the best procedure, and it is also important to maximize the lifetime of the entire network, that is, maintain full network connectivity for as long as possible.
Proceedings ArticleDOI
Cross-layer Energy Analysis of Multi-hop Wireless Sensor Networks
TL;DR: It is argued that single-hop communications has up to 40% lower energy consumption than multihop forwarding within the feasible transmission distances of an ISM radio.
Proceedings ArticleDOI
Coding for energy efficient wireless embedded networks
TL;DR: The numerical results obtained show that energy efficiencies of the codes used in a multihop routing scenario are strongly dependent on the channel conditions and on the number of hops used.
Journal ArticleDOI
Multihop medium access control for WSNs: an energy analysis model
TL;DR: In this article, the authors present an energy analysis technique applicable to medium access control (MAC) and multihop communications, which gives insight on using multi-hop forwarding instead of single-hop communications.
