Accés obertThis paper deals with the communication protocol intended to control up to 1016 devices of a new supervisory system. It has been conceived in two complementary phases. The first one (Cycle-A) is intended to inform the ... -
A GA-based simulation system for WMNs: performance analysis for different WMN architectures considering transmission rate and OLRS protocol
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertIn this paper, we evaluate the performance of two WMN architectures considering throughput, delay, jitter and fairness index metrics. For simulations, we used ns-3. We compare the performance for two architectures considering ... -
A game theoretic trust model for on-line distributed evolution of cooperation in MANETs
(2011-01-13)
Article
Accés restringit per política de l'editorialCooperation among nodes is fundamental for the operation of mobile ad hoc networks(MANETs). In such networks, there could be selfish nodes that use resources from other nodes to send their packets but that do not offer ... -
A genetic algorithm-based system for Wireless Mesh Networks: analysis of system data considering different routing protocols and architectures
(Springer, 2016-07-01)
Article
Accés obertWireless mesh networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in ... -
A multi-agent adaptive protocol for femto-satellite applications
