Abstract: The term wireless Ad Hoc network is used for the type of network that is established between communicating nodes for the specified period of time. After sometime, the nodes involve in the network move to the other location. This happens due to the wireless ad hoc network is made up of multiple mobile nodes. However, each time user changes location, the device of the user become hidden for the other nodes involved in the network to which the user’s node was connected. This sometimes becomes large problem named collision. This study provides the information related to hidden node problem and it also enlists some of the mechanism to avoid the hidden node problem. Moreover, if the hidden node problem occurred in network, even if after applying these mechanism some of the solutions to be applied to solve this problem. This study discussed about some of the protocols called MAC protocols to solve Hidden problems in wireless networks.
