Abstract

This paper presents a framework of wireless multi-hop networks exploiting an ad hoc routing protocol working on the layer 2.5, called CLARM (Cross Layer Adhoc-routing based on Reputation Management) routing protocol. The framework of CLARM routing protocol incorporates following three things: a new concept of wireless multi-hop network architecture, a new 2.5-layer routing technique with a reputation management scheme, high throughput network performance based on cross-layer approache between MAC (Medium Access Control) and CLARM layers. We compare the performance of the CLARM routing protocol with previous routing algorithms, DSR (Dynamic Source Routing) and AODV (Ad hoc On demand Distance Vector), previous reputation management scheme CORE (COllaborative REputation) and CONFIDANT (COoperation Of Nodes Fairness In Dynamic Ad Hoc NeTworks). A case study on practical experiments and simulations shows that the CLARM routing protocol yields better performance in terms of low rate of packet loss and high throughput network performance.
