Adaptive security established on the requirements and resource abilities of network nodes

Mobile wireless networks have fascinating characteristics of rapid deployment and network connectivity anywhere and anytime. Due to their very nature of being mobile, grievous security issues may arise, for which some homogeneous solutions have already been proposed. However, each node may have its own security requirements depending on the available resources and the services or applications it uses. In this paper, we propose a requirement and resource friendly security framework established on Merkle trees and then present an adaptive security service-level association (ASSA) for mobile wireless networks.
