N2 - The use of periodic invalidation reports (IRs), has been shown to be a useful technique for conserving wireless bandwidth and battery power. However, IR-based schemes have some drawbacks, such as long query delay and low client caching availability, even if the clients have sufficient local cache capacity. In this paper, we propose an efficient cache access protocol to address these problems. Instead of passively waiting, the clients use the local cache actively. Using our protocol, we can remove the "false alarm" that causes unnecessary delay. Based on our threshold-based scheme, the proposed protocol can optimize response time with little loss of data currency. Our simulation results are carried out to evaluate the proposed methodology. Compared to previous IR-based schemes, our scheme can reduce the response time significantly with a very little loss of data currency.
