Previous literatures articulated that the NDN architecture may possess unique advantages in supporting battlefield communications , and that NDN can provide superior performance over TCP/IP under various scenarios, in particular in supporting multiparty distributed applications  by using a novel dataset synchronization protocol. In this paper we first describe the designs of dataset synchronization protocols (Sync in short), in particular ChronoSync and PSync, that run over NDN to support multiparty applications, and summarize the lessons from their designs. We then perform a preliminary suitability assessment of the existing Sync protocols in ad hoc mobile environments with intermitted connectivity. Our assessment suggests that Sync protocols based on state vectors can operate most resiliently under highly dynamic conditions, and identifies remaining issues for further investigation.
