We consider the issue of which criteria to use when evaluating the design of a wireless multihop network. It is known, and we illustrate in this paper, that maximizing the total capacity, or transport capacity, leads to gross imbalance and is not suitable. ...
Securing ad hoc networks is notoriously challenging, notably due to the lack of an on-line infrastructure. In particular, key management is a problem that has been addressed by many researchers but with limited results. In this paper, we consider the case ...
Despite many good (secure) key agreement protocols based on public-key cryptography exist, secure associations between two wireless devices are often established using symmetric-key cryptography for cost reasons. The consequence is that common daily used s ...
In this paper, we propose resource allocation strategies for a class of wireless networks with a clustering protocol. The nodes are assumed stationary and establish connections with the master node according to a priority scheme that relates to their dista ...
A robust power and rate control algorithm is proposed for distributed wireless networks where the network dynamics is modelled as an uncertain discrete-time state-delayed system. ...
Inter-Vehicular Communications (IVC) are a cornerstone of the future intelligent transportation systems. A crucial enabling component of IVC is its security and privacy. Indeed, as vehicular computing systems become interconnected, there will be new venues ...
Securing ad hoc networks is notoriously challenging, notably due to the lack of an on-line infrastructure. In particular, key management is a problem that has been addressed by many researchers but with limited results. In this paper, we consider the case ...
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 ...
So far, the problem of positioning and distance measurements in wireless networks has been studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance modification attacks; we propose two ...
Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are establi ...
