In this paper, we propose a novel caching scheme, called energy efficient cooperative caching with optimal radius (ECOR), to overcome the limitations of hybrid wireless networks such as high energy consumption, long access latency and poor load balance. In ECOR, each mobile user (MU) forms a cooperation zone with MUs in proximity to share cached data items. An analytical model of ECOR is developed to determine the optimal radius of the cooperation zone based on MU's location, data popularity and node density. Experimental results show that ECOR achieves significant performance improvement in power saving, network throughput and load balance in comparison with other existing approaches. © IFIP International Federation for Information Processing 2004.
