Six state routing model (SSRM) for mobile ad hoc networks

Although there have been a number of quality of service (QoS) routing protocols already proposed for the mobile ad hoc networks (MANETs), they share the idea that one route should be selected out of all available routes based on optimizing some parameters like delay, throughput or packet loss ratio. In this paper. Six state routing model (SSRM) has been proposed for QoS through real time traffic support in MANETs. In MANETs, one hop and two hop neighborhood links break frequently due to topology updates and transmission range, which require real time recovery. SSRM addresses the key issues like frequent topology update, transmission range and steep mode by introducing different states of nodes and switching from one state to other takes place through optimization criteria such as throughput and reliability. All nodes existing in SSRM perform effective routing discovery through proactive local route information updates. This provides reliability of communication by reducing packet loss ratio and increasing packet delivery ratio in highly dynamic mobile ad hoc networks.
