为弥补传统路由协议网络实时性质量不高的缺陷,提出一种基于两跳邻居信息的功率感知实时路由算法（THPAR）,利用两跳邻居信息进行路由决策,为应对不同的包传输速率需求,融入功率控制机制动态调节节点发射功率,降低截止期错失率及链路丢包率,提高鲁棒性。改进THVR的转发能量策略,以减小能耗。对THPAR和THVR算法进行仿真实验及比较分析,结果表明,THPAR在能量有效性和延迟性方面具有优势。

To make up the defect that the real-time quality of traditional routing protocol is not high,this paper proposes a Power Aware Real-time routing algorithm based on Two-hop neighborhood information（THPAR）.THPAR uses two-hop neighborhood information for routing decisions,and employs power-control mechanism to dynamically adjust nodes＇ transmitting power in order to meet demand of different packet transmission velocity.As a result,it reduces the Deadline Miss Ratio（DMR）,link packet loss ratio and increases robustness.Besides THPAR improves fo...
