Coding Scheme Improved Query Efficiency of Hierarchical MIIS Servers with Cache in Heterogeneous Networks
The rapid development of wireless network technologies trending toward seamless heterogeneous networks, query efficiency of handover process while accessing neighboring networks for seamless mobility is a major concern issue. Our previous paper proposes Hierarchical MIIS Servers in Heterogeneous Networks by Caching (HMSHNc) in limited network, in which a hierarchical network classifies the stored information by network level (class) and distributes the location of the MIIS server cache to reduce query cost. To deal with increasing larger network, this paper proposes an enhanced method called HMSHNcC, which using the coding scheme to the ID assignment of all MIIS servers—ZMIIS, LMIIS and GMIIS. Simulation result shows the proposed HMSHNcC can satisfy to reduce query cost and to improve query efficiency.
