In wireless sensor networks (WSNs), especially in underwater networks, the problem of reporting data to sink with minimum latency has been widely discussed many research works. Many studies address using aggregation report same type without collision a short period time. However, due rapid development technology recent years, is allowed have multiple sensing capabilities, that is, it can generate and collect different types data. Because meanings required functions, only belong are be aggregated. addition, interference environment or noise, links WSNs often not bidirectional. This motivates us study scheduling aggregate multiple-data-type having unidirectional links, which shown NP-hard article. The Relative-Collision-Graph-Based Scheduling Algorithm (RCGBSA) proposed accordingly. Simulations conducted demonstrate performance RCGBSA.
