摘要：Large wireless networks are envisioned to play increasingly important roles as more and more mobile wireless devices are available to use. In these networks, it is often the case that some critical information needs to be readily accessible by the regular nodes, requiring a careful design of the information distribution technique. In this work, we propose PeB, Periodic Broadcast, that takes advantage of periodic broadcast from the information server(s) to leave traces for nodes requesting for the information. One salient feature of the PeB scheme is its periodic broadcast schedule that maintains the freshness of the trace toward the information servers. We present our extensive investigation of the PeB scheme on cost and network dynamics.
