Delays and queuing problems are common features in our daily lives. We may also find it in technical environments, such as in manufacturing, computer networking and telecommunications. Queuing theory is the mathematics of waiting lines. It has been extensively applied to represent and analyse resource sharing systems, such as communication and computer systems. Unlike traditional wireless networks that need an expensive infrastructure to support mobility, Mobile Ad hoc Networks (MANETs) are completely infrastructure-less. In MANET, each node is connected through wireless links with other nodes. Because of the limited transmission range of mobile nodes, more than one hop may be needed to send and receive data across a wireless network. Therefore in order to facilitate communication within the network, a routing protocol is used to discover paths between the nodes. Nodal mobility can …
