A Mobile Ad hoc NETwork (MANET) consists of wireless nodes that can be formed anywhere and anytime without any fixed infrastructure in which every node can act as a host or router. Nodes that want to access the channel may compete in a distributed way via Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) scheme in MAC (Medium Access Control) layer. Due to the distributed nature of the nodes and heavy traffic, packet collisions cannot be fully eliminated. MAC layer adopts Binary Exponential Backoff (BEB) for collision avoidance.
