Improved cache policy on group mobility condition in mobile Ad Hoc networks

In mobile ad hoc networks(MANETs),since mobile nodes move freely,disconnections occur frequently and unavoidably cause frequent network partitioning,and consequently data availability is decreased.Replication techniques provide a feasible solution for improving data accessibility in MANETs.The group mobility based classifying for data replica allocation(GM_Rep) is proposed to improve data accessibility by replicating data items dynamically on mobile groups.MATLAB simulation results show that the proposed algorithm greatly increases data availability in grouped mobile scenarios.
