A Resource-Efficient Adaptive Caching Scheme for Mobile Ad Hoc Networks

Abstract

In a Mobile Ad-Hoc Network environment, wireless devices have finite resources such as memory, energy and they work within the wireless constraints such as limited bandwidth and unreliable communication. Therefore, storage space, bandwidth, and battery life must be managed effectively in order to extend the usefulness and lifespan of wireless devices and the network. Caching is one of those techniques which reduce the latency and tuning time for mobile devices in the wireless network. We propose a novel scheme that seeks to distribute the storage, bandwidth and energy burden through a resource efficient adaptive caching scheme for mobile ad-hoc networks. Our performance results show that our scheme reduces both response time and bandwidth utilization by, 36%, through a reduction in hop count, as well as both a 79% increase in energy efficiency and a 53% reduction in storage utilization when compared with a leading alternate methodology.
