Video transmission over wireless network requires link reliability. Videos are having more data to be transmitted during communication. The criticality and load of the network increases when some video data is communicated over the network. Firstly, describes the characteristics of Mobile Ad hoc Networks and their Routing protocol, and second a mobile ad hoc network (MANET) which consists of set mobile wireless nodes and one fixed wireless server are design using ns-2. In this research we will simulate three MANET routing protocols such as AODV against three different parameters i.e. delay, network load, throughput and retransmission.
