Mobility-Aware Mesh Construction Algorithm for Low Data-Overhead Multicast Ad Hoc Routing
Ruiz, Pedro M.,Antonio F., Gomez-Skarmeta The Korea Institute of Information and Commucation 2004 Journal of communications and networks Vol.6 No.4
We study the problem of controlling data overhead of mesh-based multicast ad hoc routing protocols by adaptively adding redundancy to the minimal data overhead multicast mesh as required by the network conditions. We show that the computation of the minimal data overhead multicast mesh is NP-complete, and we propose an heuristic approximation algorithm inspired on epidemic algorithms. In addition, we propose a mobility-aware and adaptive mesh construction algorithm based on a probabilistic path selection being able to adapt the reliability of the multicast mesh to the mobility of the network. Our simulation results show that the proposed approach, when implemented into ODMRP, is able to offer similar performance results and a lower average latency while reducing data overhead between 25 to 50% compared to the original ODMRP.
Intrinsic and extrinsic quality of data for open data repositories
Aurora González-Vidal,Alfonso P. Ramallo-González,Antonio F. Skarmeta 한국통신학회 2022 ICT Express Vol.8 No.3
This work assesses the quality of Internet of Things data not only as an intrinsic quality on how well it represents the related phenomenon but also, on how much information it contains to educate an artificial entity. The quality metrics here proposed are tested with real datasets. Also, they are implemented on OpenCPU, so the open data repositories can use them off-the-shelf to rate their datasets without computational cost and minimum human intervention, making them more attractive to potential users and gaining visibility and impact.
