Broadcasting in UDG radio networks with missing and inaccurate information

Emanuele G. Fusco, Andrzej Pelc
2010 Distributed computing  
It turns out that this combination of missing and inaccurate information substantially changes the problem: the main new challenge becomes fast broadcasting in sparse networks (with constant density),  ...  We study broadcasting time in radio networks, modeled as unit disk graphs (UDG).  ...  It turns out that the combination of missing and inaccurate information (unknown density and unknown error in perceiving positions) substantially changes the problem with respect to the easier scenario  ...

Broadcasting in UDG Radio Networks with Missing and Inaccurate Information [chapter]

Emanuele G. Fusco, Andrzej Pelc
Lecture Notes in Computer Science  
Thus, the mere stopping requirement for the special case of the lonely source causes an exponential increase in broadcasting time, for networks of any density and any small diameter.  ...  Nevertheless, under our very weak scenario, we construct a broadcasting algorithm that maintains optimal time O min D + g 2 , D log g for all networks with at least 2 nodes, of diameter D and granularity  ...  It turns out that this combination of missing and inaccurate information substantially changes the problem: the main new challenge becomes fast broadcasting in sparse networks (with constant density),  ...

Distributed Routing for Vehicular Ad Hoc Networks: Throughput-Delay Tradeoff

Ali Abedi, Majid Ghaderi, Carey Williamson
2010 2010 IEEE International Symposium on Modeling, Analysis and Simulation of Computer and Telecommunication Systems  
Vehicular networks are highly dynamic, and hence routing algorithms that require global network state information or centralized coordination are not suitable for such networks.  ...  In this paper, we address the problem of low-latency routing in a vehicular highway network.  ...  Financial support for this research was provided by iCORE (Informatics Circle of Research Excellence) in the Province of Alberta, as well as NSERC (Natural Sciences and Engineering Research Council) in  ...

Modeling low-power wireless communications

Behnam Dezfouli, Marjan Radi, Shukor Abd Razak, Tan Hwee-Pink, Kamalrulnizam Abu Bakar
2015 Journal of Network and Computer Applications  
Third, we highlight the importance and effects of system variations and radio irregularity on the real applications of wireless sensor networks.  ...  The results presented in [12] and [15] showed the existence of radio irregularity around low-power transmitters.  ...  The existing propagation range confinement methods are either complicated and cannot be used in various network configurations, or they are very simple and cause inaccurate evaluation results.  ...
