In the coming future, a pervasive computing Environment can be predictable based on the current advancements in computing and Communication technologies. Next generation of Mobile Communications will consist of both prominent Infrastructures Wireless Networks and novel Infrastructure-less Mobile Ad hoc NETworks (MANETs). The particular features of MANET get these technology huge opportunities together with rigorous dispute. This paper illustrates the essential issues of Ad hoc Networking by giving its associated Research background consisting of the ideas, features, condition, and applications of MANET. Particular concentration is given to Network layer Routing method of MANET and main Research issues consist of fresh X-cast Routing Algorithms, Security & consistency methods, QoS model, and mechanisms for networking with outside IP Networks.
