We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...
We consider the rate allocation problem when two users (each one associated with one receiver) send packets through a symmetric broadcast channel. Under the assumption that the packet lengths are exponentially distributed, we establish the delay optimality ...
Mobility in ad hoc networks causes frequent link failures, which in turn causes packet losses. TCP attributes these packet losses to congestion. This incorrect inference results in frequent TCP re-transmission time-outs and therefore a degradation in TCP p ...
Inter-vehicle communication is regarded as one of the major applications of mobile ad hoc networks (MANETs). In these so called vehicular ad hoc networks (VANETs) security and privacy are crucial factors for successful deployment. In a scenario, where each ...
Method of detecting anomalous behaviour in a computer network comprising the steps of - monitoring network traffic flowing in a computer network system, - authenticating users to which network packets of the network traffic are associated, - extracting par ...
In this work we present a multi-path routing strategy that guarantees in-order packet delivery for Networks on Chips (NoCs). We present a design methodology that uses the routing strategy to optimally spread the traffic in the NoC to minimize the network b ...
The performance of multiband-OFDM UWB systems is analyzed using the S-V indoor channel model. Based on the analysis, two methods are proposed to improve the reliable transmission range of UWB devices by exploiting the rich spectral and spatial diversity av ...
We show that network coding allows to realize significant energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus ...
This paper presents the Simple Packet Combining (SPaC) error-correction scheme for wireless sensor networks. Nodes buffer corrupt packets, and when two or more corrupt versions of a packet have been received, a packet combining procedure attempts to recove ...
Some forms of ad-hoc networks need to operate in extremely performance- challenged environments where end-to-end connectivity is rare. Such environments can be found for example in very sparse mobile networks where nodes ”meet” only occasionally and are ab ...
