摘要
低功耗设计是MANET(Mobile Ad Hoc Network)研究中面临的一个挑战性问题。根据跨层设计思想,提出了一种基于能量约束的MANET路由算法。利用MAC层反馈信息,以分组交付所需的发送次数作为选路标准,提高分组发送的成功率,减少竞争和重传造成的功耗,从而优化网络性能。并具体结合AODV路由协议,通过仿真分析对该方案的可行性进行了评估。
Low dissipated-energy design has become a major challenge to MANET research and development activities.In this paper,the author proposes an energy-constrained routing algorithm based on cross-layer design.Using MAC-originated information, the new routing scheme selects routes according to the total sending times in the process of packets delivery,in order to enhance packets-sending fraction,reduce the energy consumption caused by competition and retransmission,and optimize network's performance.The feasibility of energy-constrained routing scheme is estimated by simulation with AODV routing protocol.
