متن کاملEfficient Channel-Hopping Rendezvous Algorithm Based on Available Channel Set
In cognitive radio networks, rendezvous is a fundamental operation by which two cognitive users establish a communication link on a commonly-available channel for communications. Some existing rendezvous algorithms can guarantee that rendezvous can be completed within finite time and they generate channel-hopping (CH) sequences based on the whole channel set. However, some channels may not be a...
متن کاملRendezvous in Highly-dynamic CRNs: A Frequency Hopping Approach
Establishing communications in a dynamic spectrum access (DSA) network requires communicating nodes to “rendezvous” before transmitting their data packets. Frequency hopping (FH) provides an effective method for rendezvousing without relying on a predetermined control channel. Current FH rendezvous designs have two main limitations. First, they do not account for fast primary user (PU) dynamics...
متن کاملOn Multi-Vehicle Rendezvous Under Quantized Communication
A rendezvous problem for a team of autonomous vehicles, which communicate over quantized channels, is analyzed. The paper illustrates how communication topologies based on uniform and logarithmic quantizations influence the performance. Since a logarithmic quantizer in general imposes fewer bits to be communicated compared to a uniform quantizer, the results indicate estimates of lower limits o...
متن کاملProtocol visualization using LOTOS multi-rendezvous mechanism
In this paper, we propose a method for visualizing LOTOS speciications using multi-rendezvous mechanism. For visualization, we have extended LOTOS by introducing some primitive animation events. Using the extended LOTOS, we describe a visualization scenario for events which we would like to visualize their execution. Then, we execute the original speciication and its visualization scenario in p...
