A Novel Cooperative Cache Policy for Wireless Networks

Table 5

The summary of the reduction ratio of the average latency and the increase ratio of the offloading ratio by comparing CPP-CC policy with the UPC, CLFU, and CLRU policies.

	SBS cache capacity: 50~ 150		Number of content requests: 3000~ 3000
	Average latency	Offloading ratio	Average latency	Offloading ratio
CPP-CC vs. UPC	9.2% ~ 10.4%	6.8% ~ 9.1%	8.9% ~ 11.1%	7.2% ~ 10.5%
CPP-CC vs. CLFU	12.8% ~ 18.5%	8.6% ~ 15.3%	12.2% ~ 18.2%	11.6% ~ 13.7%
CPP-CC vs. CLRU	37.7% ~ 40.9%	35.9% ~ 48.1%	32.8% ~ 39.7%	38.1% ~ 40.1%
