Dynamic Content Adjustment in Mobile Ad Hoc Networks

As mobile ad hoc networks are generally applied for the resource access and sharing, enormous amount of resource query may occur in a short period of time, which will easily lead to heavy traffic load in the network. Therefore, the traffic reduction for queries is an important issue. Most of the researches in this area focus on the optimal resources placement strategy under static query traffic and overlook the dynamic nature of the traffic. In this paper, we propose the Dynamic Content Grid Adjustment Strategy (DCGAS) to balance the dynamic traffic load in a network. The main feature behind DCGAS is to adjust the number of resources in a network when the query traffic exceeds or falls behind some critical thresholds. The simulation results demonstrate that our strategy outperforms the state-of-the-art data replication schemes.
