Abstract

Caching has been widely used to improve system performance in wireless mobile environment. Mobility management is a key component in allowing a client to maintain normal communication with the server while on the move, independent of its location. A cache invalidation strategy ensures that any cached item by a client has same value as on the origin server. Mobility of clients makes the cache maintenance task more complex. This paper extends our previous caching strategy in a wireless environment to handle inter-cell clients’ mobility. Experiments are performed to evaluate the proposed strategy and compare the results with other existing strategies.
