    Abstract:

    This paper presents a search algorithm called probabilistic search team (PST). In PST, all nodes advertise their resource sharing information, maintain and broadcast the information based on DDBF (distributed discarding bloom filter), which discards some information when transmitted to their neighbors. During the search process, PST extends the concept of walker in RW to search team. PST realizes collaborative and parallel search of multiple search teams by aggregating the resource information obtained in search process. Experimental results show that PST achieves a good tradeoff between performance and overhead.
