Dynamic Fusion for Ad-hoc Delay Tolerant Networks Based on Distribution Sensing

In order to ensure the self-organization of delay tolerant network can be reliable and efficient transmission of data,in order to better realize between the transmission efficiency and network overhead balance,proposed one kind based on the integration of distributed perception of self organization DTN routing algorithms.The algorithm in the analysis of self organization later network nodes based on the distribution and characteristics of distributed node density,through perception,quickly informed node distribution of regional hot spots in the network,and between the regional hot node limited dynamic routing function,to the greatest extent reduce the redundancy in the data of regional hot spots,reducing overall network transmission delay and cost effectively.The simulation results show that,the algorithm shows has obvious advantages in the transmission efficiency and delay,and effectively reduce the network redundancy overhead.
