Most of protocols which are widely used in traditional wireless network are not suitable for DTNs. DTN adopts store-and-forward mechanism to cope with the problem of intermittent path. With limited storage of each node, it is a challenge for scheduling nodes’ transmission to avoid overflow of nodes’ buffers. In this paper we propose an optimal transmission scheduling algorithm for DTN with nodes’ buffer constraints. The object of the optimal algorithm is to get maximum throughput. We also present an algorithm for obtaining suboptimal transmission schedules. Our solution is certified through simulation, and it is observed that our solution can improve network performance in the aspects of avoiding overflow and increasing network throughput.展开更多
