Abstract: The term MANET (Mobile Ad-hoc Network) refers to a multihop packet based wireless network composed of a set of mobile nodes that can communicate and move at the same time, without using any kind of fixed wired infrastructure. MANET is actually self-organizing and adaptive network that can be formed and deformed on-the-fly without the need of any centralized administration. In practice some of the nodes in MANET act as selfish node that is such kind of nodes reserve their resource and energy for its own use but they do not cooperate with other nodes in the network. This paper discusses several techniques to detect selfish nodes in MANET.
Keywords: Credit Based, MANET, Reputation Based, Selfish nodes in MANET.

Abstract: In the challenging field of software project development, the work is invariably performed by teams. In today’s world of privatization and globalization, where the development costs are increasing at a breakneck speed, the focus is now on cost reduction and availability of highly motivated and suitably trained workforce. Keeping the above mentioned parameters in mind, Companies worldwide are relying on virtual software teams to do the work. This paper highlights the characteristics and throws light on the specifics of virtual software teams. It also illustrates some of the most common issues and challenges that virtual teams face while working on a project there by exposing some of the ground realities as de scribe the most.
