A Security Framework for Buddy System based MANET Address Allocation Scheme
Security for dynamic address allocation service in Mobile Adhoc
Networks is still an open issue. This paper proposes a security
framework to thwart all possible attacks related to the buddy
system based Distributed Dynamic Address Assignment Protocol
(DDAAP) proposed by Thoppian and Prakash. Our proposed
protocol called SHEAP (Secured tHrEshold based DDAAP) is
based on a fully distributed PKI and a threshold based certified
pool address allocation model. NS2 simulation results show that,
while SHEAP is deployed, the increasing in communication
overhead and latency is quite reasonable. The availability and the
security are so guaranteed for the MANET auto-configuration
service while still ensuring efficiently both network and security
parameters for a newly arrived node.
