Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed
