Node Interactivity Self Assessment (NISA) and Data Replication in MANETs

The idea of increasing data accessibility in Mobile Ad Hoc Networks (MANETs) by replicating data still remains a challenge due to the inherent unreliable and unstable nature of MANETs. Being aware of relative host mobility changes provides useful instability information of mobile hosts and helps in managing replicas. This paper introduces a new concept as Node Interactivity Self Assessment (NISA), or more conceptual sociability, which presents the percentage of relative movement for each mobile host and can be obtained by considering the diversity of incoming requests from the nodes in the vicinity. Using this concept, we propose a novel replication technique. Simulation results show that by this technique, we achieve a balanced energy consumption as well as high data accessibility among the nodes in the network.This idea comes and being extended from the simple phrase that the more interactive you are, the more knowledge you have!
