All-to-all communication with low communication cost
In an all-to-all broadcast, every user wishes to broadcast its message to all the other users. This is a process that frequently appears in large-scale distributed systems such as voting and consensus protocols. In the classic solution, a user needs to receive n messages and n signatures where n is …

Caching techniques for reducing the communication cost of federated learning in IoT environments
… methods. These methods are intended to lower the communication demands that come with regularly updating the model between the network's edge devices and the server. High communication costs can limit the use of FL, especially in situations involving many IoT devices with restricted bandwidth and …

Energy efficient compressed sensing in wireless sensor networks via random walk
… of wireless sensor networks require we minimize communication cost for efficient power usage. At first, a compressive distributed sensing (CDS) algorithm is proposed but is then modified to decrease communication costs. The final algorithm presented is compressive distributed sensing with random …
