In wireless ad hoc networks, designing energy-efficient routing protocols is a major issue since mobile hosts are energy-limited. In this paper, we propose an energy saving cache-based routing protocol (ESCR) to address this issue. In the proposed routing protocol, when the energy of the grid header is not sufficient for data transmission, new grid header is elected directly by ESCR without the traditional grid header election. Moreover, the hosts could not wake up for registration in a period time. Therefore, the hosts could save more energy for data transmission and the routing lifetime could be prolonged. The simulation results show the routing lifetime, the host survival ratio, and the total energy consumption in comparison with existing grid-based routing protocols. Furthermore, when the host density is higher, the performance of ESCR is more outstanding.
