Description
Summary:First we introduce the characteristics of the opportunistic networks, and analyze the shortcomings of the main acquisition strategy in this kind of network, such as low success rate and low efficiency. With this in mind, we propose a hybrid strategy called "Pull-Push" Based Algorithm (PPBA). In this algorithm, not only the source node actively disseminates some copies of service information, but also the user nodes actively send their search message. Then we analyze the acquisition success rate in different strategy, and give the guide to choose the important parameter in PPBA. Finally, the simulation results show that the performance of the PPBA with different parameter in different situation, and compared with other two strategies, it also shows a better performance on acquisition success rate in opportunistic networks.
