Delay tolerant network (DTN) is opportunistic network where each nodesearches best opportunity to deliver the message called bundle to thedestination. DTN implements a store and forward message switching system bysimply introducing another new protocol layer called the Bundle Layer on top ofthe transport layer. The bundle layer is responsible for storing and forwardingentire message in message segments called bundles between source node anddestination node. This paper evaluates the performance of delay tolerantnetwork layer in heterogeneous highly dense mobile node environment. Theheterogeneous network is created with the help of stationary wired node andBase Station node by introducing dynamic dense Mobile node network. Mobilenodes are assigned with continuous mobility. Three parameters are suggested$\Delta$, $\Theta$ and $\lambda$ to correlate the results obtained usingrigorous simulation. Results show that after some threshold values, densefeature about mobile node does not pretend the delay cause for delay tolerantnetwork packets. Also, increase in number of mobile node and number of FileTransfer connection rarely change the overall performance of the delay tolerantnetwork.
