Abstract: A cross-layer optimization based routing protocol for Real-Time Energy-Balance(RTEB) is proposed, which achieves application-specified communication delays by collaborative design of MAC and routing. RTEB features an energy-balance forwarding policy and an active congestion control mechanism that are optimized for resource-constrained multimedia sensors. Simulation experiments show that RTEB effectively reduces the number of deadlines missed and energy consumption.

摘要： 提出一种能量均衡的实时路由算法。通过MAC层和路由层协同设计，在路由转发策略中，充分考虑节点的剩余能量和可靠性。在拥塞控制机制中，基于节点的缓存队列长度并结合收发数据速率来检测拥塞。仿真实验显示，该路由算法有效地保证了数据的实时传输，降低了通信能量的开销。
