Abstract
This work proposed a clustering scheme for Point Of Interests’ (POIs’) geo data sharing in Vehicular Social Network (VSN). In the proposed scheme, some vehicles can form a cluster to downloaded POIs’ geo data when they are approaching to a new set of POIs. One vehicle is chosen as the cluster head to download POIs’ geo data using its cellular network and shares the downloaded POIs’ geo data to its cluster members using IEEE 802.11p network. This work (1) uses GPS to get vehicles’ locations to calculate the timing of triggering the clustering process, and (2) proposes a clustering method to organize a group of vehicles that are proximate with each other for a while during their touring to become a cluster. The simulation results show that the proposed scheme can have higher available distance and higher successful ratio of the complete sharing of downloaded POIs’ geo data.
Highlights
Vehicular Social Network (VSN) is a special kind of Mobile Social Networks (MSN) that can connect nearby vehicles with common interest to perform some social interactions, e.g., downloading and sharing some geo data of Point Of Interests’ (POIs)
If cluster head Hi, i=1... m-1, m-2, .. d, reaches its GPS sampling time point, i.e., the SPd time point depicted in Figure 4, and still does not receive the JOIN_CONFIRM (Y, Cluster_ID) message sent from vehicle Y, it means that Y does not join Hi’s cluster, i=1... m-1, m-2 ... d
To avoid the situation that (1) cluster members and cluster head drive to different roads, e.g., cluster head or some cluster members drive to the other road in a road intersection, or (2) the connected time between cluster head and it cluster member is not enough due to the sudden speed up/down of vehicles, the VSN server periodically checks whether the topology of each cluster keeps the same or not
Summary
Vehicular Social Network (VSN) is a special kind of Mobile Social Networks (MSN) that can connect nearby vehicles with common interest to perform some social interactions, e.g., downloading and sharing some geo data of POIs. The cluster head is in charge of downloading POIs’ geo data using cellular network and forwarding the downloaded data to other vehicles using IEEE 802.11p Dedicated Short Range Communication (DSRC) network. To tackle the issue for POIs’ geo data sharing in VSN, a clustering scheme was proposed in this work. In this way, proximate vehicles that belong to the same VSN can form a cluster to share downloaded POIs’ geo data, in which cluster head downloads POIs’ geo data using its cellular network and shares the downloaded data to its members using IEEE 802.11p DSRC network.
