Middleware design of bandwidth constrained QoS model for multi hop ad hoc networks

Middleware is actually a resource manager that guarantees the implementation of all policies, contracts to be satisfied, and it ensures that contracts do not go beyond the limits of network capacity. It also authentication, so that only the legitimate users could avail the network resources according to the agreed format. The middleware is supposed to be the backbone for QoS assurance and the system behavior depends on it. This paper proposes design of a middleware based on a bandwidth constrained QoS model for multi hop ad hoc networks. Our model is designed not only on the basis of conceptualization but we have considered the basic functionalities available in networking equipments like routers etc. The elements of QoS aware middleware are admission control, resource reservation, policy control and a feedback module. Finally we discuss our future work to find the primary and alternative route to the destinations by keeping the bandwidth constraints in mind.
