中文摘要：
针对机会网络中的节点能耗与消息扩散程度之间存在矛盾,基于节点能耗与副本状态感知的路由机制可以显著地改善资源受限场景的网络性能,综合考虑消息扩散程度与节点剩余能量,并结合节点相遇概率预测方法,提出能量有效的副本分布状态感知路由机制,为消息分布式地选择合理的中继节点。仿真结果表明,所提出的路由机制能够有效降低网络负载,并大幅改善消息投递率和平均时延性能。
英文摘要：
In opportunistic network, the relation between the node energy and message spreading degree is tradeoff. As a result, the network performance can be dramatically improved in limited resource scenarios by an effective routing mechanism considering the node energy and copy status. Both the message spreading degree and node residual energy were taken into consideration, and then combined with the encounter probability predicting methods, an energy efficient copy distributing status aware routing mechanism was proposed, which could be used to choose the relay nodes reasona- bly. Numerical results show that the overhead can be reduced efficiently, and the message delivery ratio and latency can also be ootimized.
