Abstract: Mobile Ad hoc Networks (MANETs) in terms of resources, robustness and efficiency for replicated service applications. Most of the anycast routing protocols select unstable and congested intermediate nodes, thereby causing frequent path failures and packet losses. We propose a mobility and quality of service aware routing scheme in MANETs that employs three models: node movement stability, channel congestion, and link/route expiry time. These models are used in the route discovery process to select nearest k-servers. A server among k-servers is selected based on less congestion, route expiry time, number of hops, and better stability. The simulation results indicate that proposed method demonstrates reduction in control overheads, path delays and improved packet delivery ratio compared to existing methods such as queue utilization, residual energy and node degree.
