In this paper, we proposed the context-awareness routing algorithm DDV (Dynamic Direction Vector)-hop algorithm at Mobile Ad-hoc Networks. Existing algorithm in MANET, it has a vulnerability that the dynamic network topology and the absence of network expandability of mobility of nodes. This proposed algorithm forms cluster formation using a range of direction and threshold of velocity by base-station, and we calculate exchange cluster head node probability using direction and velocity for maintaining cluster formation. DDV algorithm forms a cluster based on the cluster head node. As a result of simulation, our scheme could maintain the proper number of cluster and cluster members regardless of topology changes. In response to maintain cluster formation, we prove a continuous connection between nodes.
