Multi-hop wireless networks (such as ad-hoc or sensor networks) consist in sets of mobile nodes without the support of a pre-existing fixed infrastructure. For scalability purpose...
An ad-hoc network is the cooperative engagement of a collection of typically wireless mobile nodes without the required intervention of any centralized access point or existing ...
In this paper we present a protocol for sensor applications that require periodic collection of raw data reports from the entire network in a timely manner. We formulate the probl...
—Wormhole attack is a severe threat to wireless ad hoc and sensor networks. Most existing countermeasures either require specialized hardware devices or make strong assumptions o...
