The world is going wireless and the user-services are being mobile. With the characteristics like self-creation, self-organization and self-administration, Mobile Ad-hoc NETworks (MANETs) have become a great asset to this wireless world. MANETs are infrastructure-less and autonomous. This paper touches some major technical issues like security and service discovery, and their possible solutions for MANETs. A MANET is a self configuring network formed by mobile hosts having wireless communication devices. Main features of MANET are multi-hop and mobility. It can be standalone or can be connected to Internet. As communicating nodes might be out of range, the nodes must be able to relay traffic. All the nodes in MANET use same frequency spectrum or physical channel.
