— The proliferation of wireless and mobile devices has fostered the demand of context aware applications, in which location is often viewed as one of the most significant context...
The Sybil attack in unknown port networks such as wireless is not considered tractable. A wireless node is not capable of independently differentiating the universe of real nodes f...
— In this paper we study a simple protocol utilizing two-hop cooperative diversity augmented with “automatic repeat request” (ARQ) for multi-hop ad-hoc networks. This protoco...
— This paper discusses a joint decentralized clustering and ranging algorithm for wireless ad-hoc sensor networks. Each sensor uses a random waiting timer and local criteria to d...
In this paper, we develop adaptive metrics to identify stable links in a mobile wireless networking environment based on the analysis of link durations in several different mobili...
