Growth Rate of Cached Data Items at clients in Mobile Ad Hoc Networks

摘要

Data Caching on mobile clients is widely seen as an effective solution to increase data availability. A population is a “group of plant, group of people, and group of animal etc.” all is same species that live together and reproduce. Here a group of cached data items at clients in mobile ad hoc network called Group of Cached Data items (GCD). In this paper, the growth rates of cached data items at clients in mobile ad hoc network calculated by using population dynamic model reflect the status of the regional group of cached data item at clients over the most recent period, called Growth Rate of Group of Cached Data Items. Here, we give two models: independence and dependence model. Independence model, cached data item growth is based on the concept that the cached data item grows at the same rate. Dependence Model, cached data item growth is based on the concept that the data item grows at the different rate because growth rate is depends on Birth Rate of Data item (BRD) and Death Rate of Data item (DRD).
