Ultra Wide Band (UWB) technologies have attracted a lot of attention recently due to their large bandwidth and low emission, which are suitable for in-door, high-speed multimedia c...
We describe a novel Geometric Localized Routing (GLR) protocol in Disruption (Delay) Tolerant Network (DTN). Although DTNs do not guarantee the connectivity of the network all the...
Building a “Straightforward” path in wireless ad hoc sensor networks (WASNs) not only avoids wasting energy in detours, but also incurs less interference in other transmission...
Broadcast of information in wireless sensor networks is an important operation, e.g., for code updates, queries, membership information, etc. In this paper, we analyze and experim...
We introduce a dynamic battery model that describes the variations of the capacity of a battery under time varying discharge current. This model supports a co-design approach for ...
