Robust quality of service backbone for mobile ad hoc networks

Mobile ad hoc networks (MANETs) are a rapidly growing field today. Unlike conventional wireless networks, MANETs have no physical backbone infrastructure and no administrative support. Generally, these networks are characterized by scarce resources (e.g. bandwidth, power, etc.), high error rates, and a dynamic topology. In MANETs, the quality of service (QoS) aspect, in general, and QoS routing, in particular, need more attention as a result of the rising popularity and necessity- of real-time multimedia applications. Currently, no robust QoS backbone algorithm can efficiently serve a MANET environ. This paper proposes a novel QoS backbone construction algorithm for MANETs. The backbone nodes are mainly selected based on individual node stability and available bandwidth for each node. Then, these nodes are implicitly connected using link bandwidth and delay as QoS metrics. The proposed algorithm, its performance analysis, and simulation results are presented in this paper
