Abstract
In the mobile ad-hoc network (MANET), mobile nodes can freely move to anywhere whenever they want to. As MANET is no communication infrastructure, the route maintenance for transmitting the data and the volume of being transmitted data are important issues. In this paper, we adopt the content caching scheme to reduce the consumption of network bandwidth and node’s battery power. The proposed caching scheme stores the data being delivered by a neighboring node located in 1 hop away from itself. This has resulted in the increases of the probability that a mobile node stores the data to be used in future request. In evaluation, we examined our proposed scheme in the view of the cache hit ratio as the function of the number of mobile nodes and 4 mobility models: random way point, random direction, boundless simulation area and Gaussian-Markov. From simulation results, we confirm that the proposed scheme offers better performance substantially.
