摘要：
To solve the shortcomings in Energy-efficient Routing algorithm Based on Cross-layer design (ERBC), an Efficient Energy-saving Routing Algorithm for Opportunistic Networks based on Power Control and Waiting Time Estimation (EERPW) is proposed. The EERPW designs a new adaptive dynamical power control mechanism, in which data packets are forwarded after conditionally waiting for a period of time when two nodes are approaching to each other. Waiting time is added to improve accuracy of power control. Besides, the acknowledgement (ACK) is extended to use to improve the RSSI-based ranging mechanism, thus enlarging the range of power control to more messages. Simulation results show that EERPW has lower per-bit energy consumption and control overhead compared with the existing three relative algorithms ERBC, Epidemic and n-Epidemic. © 2015 by Binary Information Press.
