ON-CRP:cache replacement policy for opportunistic networks
Ming Zhao · Journal of Communications · 2010
A novel cache replacement policy was proposed,which referred as ON-CRP(opportunistic networking cache replacement policy).Differing from most of existing policies,ON-CRP choosed the data item to replace based on the correlation between the nodes and the item.It utilized the probability of destination-matching to judge the correlation which was gotten from humans' mobile patterns.Moreover,the visit and update frequency ratio was used to design the standard of cache data replacement.The simulation results show that ON-CRP policy can reduce the latency of remote data access.Furthermore,the resource consumption is reduced about 30% while cache hit ratio of data is improved about 10%～30%.
