A Novel Methodology For Securing Ad Hoc Network By Friendly Group Model

摘要

MANETs may be considered as a society in which nodes agree to cooperate with each other to fulfill the common goal. But noncooperation is genuine to save itself in terms of their battery power and bandwidth. Ad hoc network is still a challenge as lots of work has been proposed but they have serious limitations in terms of routing overhead and attacks. Modification of routing information's can be handled by secure routing protocols but non cooperation is still in its natal stage. Our proposed FG Model minimizes resource utilization by cutting down the routing overhead, so that less number of nodes participates in routing activities by creating smaller friendly groups. The proposed method minimizes routing overhead to a ratio of k:1|k＞1 (where k is the no. of friendly groups) and it can be implemented on the existing MNAET routing protocol (e.g., DSR, AODV and TORA).
