Mobility-Aware Adaptive Counter-Based Forwarding Elimination to Reduce Data Overhead in Multicast Ad Hoc Routing
Most of the previous efforts regarding multicast routing in MANETs, have been devoted to the provision of low-control overhead protocols, being able to maximize the packet delivery ratio. In multicast routing, the non-optimality of the forwarding structure can also lead to transmission of additional data packets (compared to the minimum required). The authors call those additional data packets data-overhead. In this paper, they present a counter-based forwarding elimination scheme, being able to reduce that overhead depending upon the mobility of the nodes. Their results show that this approach is able to enhance the bandwidth consumption of mesh-based multicast ad hoc routing protocols while maintaining nearly the same packet delivery ratio.
