计算和协议管理的能源意识正在成为协议和算法设计中的一个关键因素。另一方面，为了支持节点的移动性，设计了可扩展的路由策略，这些协议试图考虑路径时长，以尊重某些服务质量约束，减少路由发现过程。通常，节能和路径持续时间和稳定性可能是两个截然不同的努力，试图同时满足这两个目标可能非常困难。本文提出了一种新的路由策略。这种提出的方法试图考虑链路稳定性和最小排泄率能耗。为了验证所提方案的正确性，设计了一种双目标优化公式，并提出了一种新的路由协议--链路稳定和能量感知路由协议(LAER)。与其他三种协议Perra、GPSR和E-GPSR进行了比较。从数据包投递率、归一化控制开销、链路时长、节点寿命和平均能量消耗等方面对协议的性能进行了评估。
Energy awareness for computation and protocol management is becoming a crucial factor in the design of protocols and algorithms. On the other hand, in order to support node mobility, scalable routing strategies have been designed and these protocols try to consider the path duration in order to respect some QoS constraints and to reduce the route discovery procedures. Often energy saving and path duration and stability can be two contrasting efforts and trying to satisfy both of them can be very difficult. In this paper, a novel routing strategy is proposed. This proposed approach tries to account for link stability and for minimum drain rate energy consumption. In order to verify the correctness of the proposed solution a biobjective optimization formulation has been designed and a novel routing protocol called Link-stAbility and Energy aware Routing protocols (LAER) is proposed. This novel routing scheme has been compared with other three protocols: PERRA, GPSR, and E-GPSR. The protocol performance has been evaluated in terms of Data Packet Delivery Ratio, Normalized Control Overhead, Link duration, Nodes lifetime, and Average energy consumption.
