In this paper, the authors examine the question of designing and allocating transmission sequences to users in a mobile ad hoc network that has no spatial boundary. A basic tenet of the transmission sequence approach for addressing the media access control problem is that under normal operation conditions, there is no feedback based re-transmissions. This obviously is a major departure from the Slotted-ALOHA or CSMA type approaches. While these latter solutions enjoy excellent throughput performance, a fundamental drawback is that they are based on information feedback. For systems in which there is no unique, naturally defined central controller that plays the role of a base station, the task of providing feedback information could easily become unmanageable.
