Fuzzy-controlled cache management (FCM) in Experience-based Energy-efficient Routing Protocol in ad hoc networks

A mobile ad hoc network is an infrastructure less network where the nodes can move freely in any direction. Since the nodes have limited battery power, energy efficient route discovery mechanisms are critical for proper performance of this kind of networks. Experience-based Energy-efficient Routing Protocol (EXERP) [1] is one such protocol that intelligently addresses this issue and it requires two caches, namely, history cache (H-cache) and packet cache (P-cache). These two caches are dependent upon one another. In this article, we propose a fuzzy controlled cache management (FCM) technique for EXERP in ad hoc networks. Simulation results establish that the proposed scheme achieves a high hit ratio at low complexity than other cache management schemes.
