A comparative study of on-demand and cluster-based routing protocols in MANETs

We introduce the virtual base station on-demand (VBS-O) routing protocol for wireless mobile ad hoc communications, which built on top of any mobile infrastructure protocol, the warning energy aware clusterhead (WEAC) infrastructure protocol. The WEAC protocol establishes a dynamic wireless mobile infrastructure to mimic the operation of the fixed infrastructure in cellular networks. In the WEAC protocol, a mobile station is elected from a set of nominees, based on its energy level, to act as a temporary base station within its zone. Mobile stations elected as VBSs are used to track other mobile stations in the ad hoc network. The VBS-O routing algorithm utilizes the mobility-tracking mechanism of the WEAC infrastructure creation protocol to route the packets. The VBS-O architecture complying with QoS guarantees imposes the use of a MAC method that guarantees the successful transmission of packets under high mobility and/or heavy load circumstances, and hence meets the QoS constraints dictated by the communications application.
