Friend and point-of-interest (POI) recommendation are two primary individual services in location-based social networks (LBSNs). Major social platforms such as Foursquare and Instagram are all capable of recommending friends or POIs to individuals. However, most of these social websites make recommendations only based on similarity, popularity, or geographical influence; social trust among individuals...
Aiming at the problem that existing network performance measurements have low accuracy for (Request for Comments) RFC 2544, this paper proposes a high-speed network performance measurement based on field-programmable gate array (FPGA). The active measurement method is used to generate probe data frames, and a passive measurement method is employed to count network traffic. According to the statistical...
This paper studies the capacity of hybrid wireless networks with opportunistic routing (OR). We first extend the opportunistic routing algorithm to exploit high-speed data transmissions in infrastructure network through base stations. We then develop linear programming models to calculate the end-to-end throughput bounds from multiple source nodes to single as well as multiple destination nodes. The...
