Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...
Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. To cope with misbehavior in such self-organized networks, nodes need to be able to automatically adapt their strategy ...
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 ...
This thesis is primarily concerned with two security mechanisms for wireless networks: location verification and key management. These mechanisms are potential building blocks in the security architectures of a range of applications. Under location verific ...
Misbehavior in mobile ad-hoc networks occurs for several reasons. Selfish nodes misbehave to save power or to improve their access to service relative to others. Malicious intentions result in misbehavior as exemplified by denial of service attacks. Faulty ...
We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...
In this paper, we propose a power control strategy for distributed wireless networks by using a quadratic state-space control design. Simulation results show the effectiveness of the proposed power control algorithm. ...
How efficiently can a malicious device disrupt a single-hop wireless network? Imagine two honest players attempting to exchange information in the presence of a malicious adversary that can disrupt communication by jamming or overwriting messages. Assume t ...
There is a fundamental tradeoff between power consumption, data transmission rates, and congestion levels in a wireless network. These three elements influence the performance of rate and power control strategies, and they need to be coordinated judiciousl ...
