Group establishing algorithm for strategic mobile scenario in MANETS

摘要

Wireless communication network has such features as limited bandwidth, changeful channel and dynamic topology, etc. In MANETS, the performance is significantly degraded as the scale of the network grows, which has lots of difficulties in accessing control, bandwidth distribution, resource assign and congestion control. Therefore, in this paper, we have proposed an online self-organized group establishing mechanism for strategic mobile scenarios of MANETs to realize the maneuverability of putting the secure group operations into effect. First of all, the algorithm performs initialization for each node, and then the nodes determine group-manager based on condition function and invite neighboring nodes to join in, finally, the rest nodes without grouping confirm their own groups by the group condition function. Both theoretical analysis and simulation experiments have demonstrated that our method can meet the scalability requirement which plays an important role in prolonging the network lifetime and effectively saving the communication, computation and storage overhead in strategic mobile scenario of MANETs.
