Several misbehavior detection and reputation systems have been proposed for mobile ad-hoc networks, relying on direct network observation mechanisms, so-called watchdogs. While these approaches have so far only been evaluated in simulations and restricted ...
The vision of nomadic computing with its ubiquitous access has stimulated much interest in the mobile ad hoc networking (MANET) technology. However, its proliferation strongly depends on the availability of security provisions, among other factors. In the ...
We investigate secure routing in ad hoc networks in which security associations exist only between a subset of all pairs of nodes. We focus on source routing protocols. We show that to establish secure routes, it is in general not necessary that security a ...

Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is ...
Mobile ad-hoc networks rely on the cooperation of nodes for routing and forwarding. For individual nodes there are however several advantages resulting from noncooperation, the most obvious being power saving. Nodes that act selfishly or even maliciously p ...
In this paper we propose a novel approach for multicasting in Mobile Ad-hoc Networks (MANETs). Since no fixed infrastructure of servers is assumed in MANETs, efficient location management schemes are necessary in order to store and provide information abou ...
Providing reliable group communication is an ever recurring issue in distributed settings. In mobile ad hoc networks, this issue becomes more significant since all nodes act as peers, while the issue gets even more challenging due to highly dynamic and unp ...
We propose a micro-payment scheme for multi-hop cellular networks that encourages collaboration in packet forwarding by letting users benefit from relaying others` packets. At the same time as proposing mechanisms for detecting and rewarding collaboration, ...
In this paper we propose a new probabilistic Fair Exchange Protocol which requires no central Trusted Third Party. Instead, it relies on a virtually distributed and decentralized Trusted Third Party which is formalized as a Guardian Angel: a kind of Observ ...
