Ad-hoc networks formed by peers without relying on any preexisting infrastructure, have been a very attractive field of academic and industrial research in recent years due to their potential applications. An ad-hoc network allows a peer node further to form a task-driven sub-network such that each node in the generated sub-network may exchange data with each other but any other non-member node is...
