Communication packet conversion
View Patent ↗Techniques for converting communication packets in a network having multiple nodes are described herein. A node may receive communication packets from one or more neighboring nodes. Each communication packet may include control data and payload data. The node may extract the payload data and store the payload data for a time period. The node may determine whether to concatenate the extracted payload data of the communication packets (e.g., based on destinations to where each of the extracted payload data are to be sent, a supported data rate, an application type associated with the extracted payload data, etc.). The node may concatenate the extracted payload data of the communication packets and send the concatenated payload data to another node in a communication packet.
