He-SERIeS: An inventive communication model for data offloading in MANET

Mobile Ad-hoc Network (MANET) is the dynamic infrastructure-less network that contains a heterogeneous wireless mobile devices. There are several issues that can occur in MANET such as limited bandwidth, dynamic topology, routing overhead, and battery constraints. In this paper, the heterogeneous MANET comprising of different MAC layer protocols are considered. The problems faced by the Heterogeneous Secure-dEed-Reflection-Inducement-eState (He-SERIeS) algorithm are scalability and offloading. In order to resolve these challenges of the existing SERIeS algorithm, a He-SERIeS algorithm is designed. The Cluster Head (CH) is elected using the on-demand clustering algorithm and the nodes with similar requirements are clustered into a distinct cluster using the similarity measure algorithm. The auxiliary key management schemes such as MD5 and SHA1 are used to predict the faulty nodes. The performance of the proposed He-SERIeS algorithm is analyzed with the existing algorithms such as Random Cache (RC), Centrality based Cache (CC), Set Cover Based Caching (SCBC) and SERIeS algorithm. The metrics used for comparison are throughput, Packet Delivery Ratio (PDR), end-to-end delay, replication overhead and offloading ratio. The proposed scheme achieved 92.8% PDR, a high throughput of 96.6% and a high offloading ratio of 0.532, less replication overhead, and end-to-end delay.
