  • Taking mobile pattern into consideration
    can bene¯t routing performance in Delay tolerant networks
    (DTN). Based on common sense, the more similar the mo-
    bile patterns of nodes are, the more stable their relative
    positions are resulting in a connection with a longer du-
    ration. In this paper, a scheme named Similarity degree
    based Mobile pattern aware routing (SD-MPAR) is pro-
    posed. A comprehensive metric called similarity degree is
    applied to scale the degree of similarity between the mobile
    pattern of nodes which includes deviation of the sender's
    speed direction from that of the destination, and distance
    from the sender to the destination. Similarity degree is
    also a key factor to decide the next hop. A message is
    forwarded to the next hop node with the largest similarity
    degree. Through theoretical analysis and simulation, SD-
    MPAR shows the advantages deliver ratio, overhead, de-
    liver latency and average number of hops over other rout-
    ing schemes including epidemic and distance-based rout-
    ing.
