The area of MANets is still in its infancy in the research community, but it plays a vital role surrounded by the growing trend of mobile technology for business, private and governmental uses. Ubiquitous and pervasive computing concept is almost intrinsically tied to wireless communications. Emerging next-generation wireless networks enable innovative service access in every situation. Apart from many remote services, proximity services (context-aware) will also be widely available. People currently rely on numerous forms of identities to access these services. The inconvenience of possessing and using these identities creates significant security vulnerability, especially from network and device point of view in MANet environments. The emergent notion of ubiquitous computing also makes it possible for mobile devices to communicate and provide services via networks connected in an ad hoc manner. Digital identity is at the heart of many contemporary strategic innovations, ranging from crime, internal and external security, business models etc. This requires disclosing personal information and the applicability of contextual information as well as allowing users to be in control of their identities. We illustrate the requirements and framework to develop an innovative, easy-to-use identity management mechanism within MANet environment. We convey various possibilities, challenges, and research questions evolving in these areas. The issue of context-awareness and making use of partial identities as a way of protecting user’s identities as well as providing a better way of identifying nodes has been addressed. We also examined the area of user-centricity for MANets together with its security issues and implications. We propose a framework for MANets that makes the flow of partial identities explicit and gives users control over such identities based on the respective situation and context as well as it creates a balance between convenience and privacy.
