Defending against denial-of-service (DoS) in a mobile ad hoc network (MANET) is challenging because the network topology is dynamic and nodes are selfish. In this paper, we propos...
We propose a new routing graph, the Restricted Delaunay Graph (RDG), for ad hoc networks. Combined with a node clustering algorithm, RDG can be used as an underlying graph for geo...

As small digital cameras become more popular, opportunities to take photos are rapidly increasing. Photo sharing is a great way to maintain and revitalize relationships between fa...
In this paper we present SECTOR, a set of mechanisms for the secure verification of the time of encounters between nodes in multi-hop wireless networks. This information can be u...
In typical single-link 802.11 ad-hoc networks, devices often move from one network to the next, forming transitory associations without a fixed support infrastructure. The state i...
