Mobility in wireless sensor networks can negatively impact latency for data transfer. As mobile nodes move, established links can deteriorate and disconnect, requiring the mobile node to repeatedly form new links with surrounding relay nodes. This new link formation leads to extra latency as data communication is interrupted. The paper sets up a mathematical model and runs simulations to analyze how latency is affected by increasing network density and duty cycle as node mobility rises. Both the model and simulations show that latency goes up with greater mobility from more network nodes and higher radio duty cycles.
