Group adaptive hybrid routing algorithm based on group mobility in Tactical MANET

Routing algorithm is very important in MANET. In Tactical MANET, nodes usually form many groups, and inner-group nodes generally have similar moving rules, the topology of one group is thus inner-stable. According to the inner-stable group feature, a group adaptive hybrid routing algorithm (GAHRA) based on group mobility is proposed, which applies table-driven routing process in stable groups and on-demand routing process between mobile groups. Based on the paper provided adaptive mechanism for switching between table-driven routing and on-demand routing algorithm, every nodes can thus distinctly improve the performance of Tactical MANET routing algorithm. Theoretical analysis and simulation results show that the proposed algorithm is superior to conventional single routing algorithms and more suited for Tactical MANET application.
