中文摘要：

基于已有容迟网络（DTN）路由算法对能量考虑不足的问题，提出了基于能量约束和历史信息的DTN路由算法（ERHR），并在The One（the opportunistic networking environment）平台上，用Java语言进行仿真比较．仿真结果表明，ERHR在能量消耗、传递成功率和平均缓冲时间等性能上优于其他DTN路由算法，适应DTN网络的需求，是一种有效的DTN网络路由解决方案．

英文摘要：

Some delay-tolerant network（DTN） routing algorithms considered little on energy, so a DTN routing algorithm is proposed based on energy restriction and history information（ERHR）, and realized simulations on a platform using Java. Simulation results showed that ERHR has better performance in energy-consumption, successful delivery ratio and average buffering time than other DTN routing algorithms. ERHR can suit the need of DTN. ERHR is an effective DTN routing algorithm.
