Ad hoc network is a wireless network without having fixed equipment/components. Here, the mobile device functions as an endpoint as well as intermediate point. The intermediate points (devices) are used to forward the message if the two wireless mobile nodes are not within their transmission range. Current communication system is playing an important role to allocate the resources for the multimedia applications. This chapter discusses the various algorithms for the mobile wireless ad hoc networks, which is an efficient method to allocate the resources for the sensitive applications using the weighted fair queue system. This method is very important during the period of network congestion. This system allocates sufficient bandwidth and provides quality of service to the end-users. This chapter also talks about the quality of services at various layers of open system interconnection model. Adaptation schemes provide different levels of service to different classes of traffic. Some of the quality of service schemes propose that the class of traffic should be modified as a result of events occurring in the network. The quality of service driven resource management architecture is used to serve as a system-wide framework within which resource management decisions can be performed in a coordinated fashion. The resource allocation scheme for multimedia applications using mobile agent is used to allocate the resources in the mobile ad hoc network. In addition to that it allocates the resources for hand-off applications and new applications.
