基于两跳邻居信息的功率感知实时路由算法
Power Aware Real-time Routing Algorithm Based on Two-hop Neighborhood Information
摘要
Abstract
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 forwarding energy policy of THVR, it reduces the energy consumption. Simulation and comparison analysis between THPAR and THVR are done. Simulation results show that THPAR can perform better than THVR in term of energy consumption and delay.关键词
