Cache Coherency Algorithm to Optimize Bandwidth in Mobile Networks

Abstract

Mobile networks are becoming popular in catering to Internet through smart phones. The next generation phones provide ubiquitous communication of voice, video and data through the hand held devices. Unfortunately, the increase in service provider capacity has not kept up with the user demand for more bandwidth. It is becoming very expensive for service providers to cater higher bandwidth without investing on new technology or expansion. In this paper we propose a bandwidth optimization algorithm based on cache coherency where the user data transfer is optimized without compromising the user expectation or the need for service providers to expand their capacity. The proposed algorithm is compared with existing data transfer techniques and we show through representative analysis the efficiency of the algorithm to keep the same level of communication with less transfer. To emphasize the practicality of the algorithm, we also provide some insights into how it is implemented.
