In recent years, the growth of Mobile Computing, Electronic Commerce and Mobile Electronic Commerce has created a new concept of Mobile Electronic Marketing. New marketing models are being developed and used to target mobile users. Mobile environments introduces new challenges that need to be overcome by these marketing models in order to be successful and effective. This paper proposes a framework, called eNcentive, which addresses many of the issues that are characteristic of mobile environments. eNcentive facilitates peer-to-peer electronic marketing in mobile ad hoc environments. Our framework employs a intelligent marketing scheme, by providing users the capability to collect information like sales promotions and discounts. Users can propagate this marketing information to other users in the network. Participating users benefit from such circulation since businesses that originally created the promotions reward the active distributors with additional promotions and other compensations.

A mobile ad-hoc network is an autonomous system of mobile routers that are self-organizing and completely decentralized

Abstract-Policy based networks provide high levels of flexibility by allowing definition of packet handling rules within a network, resource allocation strategies, network management, or access control. Commonly used policy specification mechanisms are, however, limited in their expressibility and rely mostly on packet headers that convey limited information about the semantics of the content. We propose a new model for policy based networking that utilizes the W3C Web Ontology Language tags carried in data packets that can provide detailed semantic information about the packet or stream. Using this model, a policy decision point can reason over these tags and infer the correct set of operations to invoke. Policies are expressed in the W3C Semantic Web Rule Language using a common ontology and take into consideration the content of the streams, relevant contextual information and external domain constraints. Using this framework, fine grained, highly specialized services can be offered within the network that are context-aware, easy to manage, deploy and verify for consistency.

The pervasive computing environments of the near future will involve the interactions, coordination and cooperation of numerous, casually accessible, and often invisible computing devices. These devices, whether carried on our person or embedded in our homes, businesses and classrooms, will connect via wireless and wired links to one another and to the global networking infrastructure. The result will be a networking milieu with a new level of openness. The localized and dynamic nature of their interactions raises many new issues that draw on and challenge the disciplines of agents, distributed systems, and security. This paper describes recent work by the UMBC Ebiquity research group which addresses some of these issues.
