In this paper we consider the problem of searching for a node or an object (i.e., piece of data, file, etc.) in a large network. Applications of this problem include searching fo...
Topology control algorithms usually reduce the number of links in a wireless network, which in turn decreases the degree of connectivity. The resulting network topology is more su...
Sensor networks are often desired to last many times longer than the active lifetime of individual sensors. This is usually achieved by putting sensors to sleep for most of their ...
Interactive communications among nodes in Vehicular Ad Hoc Networks (VANET) and the safety-oriented nature of many VANET applications necessitate a robust security framework. An a...
We present a new protocol for routing in multi-radio, multi-hop wireless networks. Our protocol, Multi-Radio Link-Quality Source Routing, is designed for wireless networks with st...
