Role management in adhoc networks

The purpose of an ad-hoc network is to enable interactions among its participants. It is thus important to ensure that these interactions are governed by well-defined policies that define the rules for accessing services and resources in the network. In order to address explicit specification of policies for each activity, an architectural framework is proposed to adapt policy based access control called role based access control (RBAC) model in the MANET environment. We analyze the possible wireless adhoc communication environment with respect to security and propose a layer where routine or dynamic analysis of adopted roles by devices can be formulated. We present analysis of such parameters and show that framework for these parameters within the proposed layer leads to better management during time critical operations of wireless adhoc networks.
