In Mobile Ad Hoc NETworks (MANETs), routing is a challenging task due to node mobility, traffic and network size. It is very important to analyze the scalability characteristics of the routing protocols with respect to these parameters. Zone Routing Protocol (ZRP) is considered to be one of the most scalable routing protocols due to its multi-scoping and hybridization features. The authors propose a general, parameterized model for analyzing control overhead of ZRP. A generic probabilistic model for data traffic is also proposed which can be replaced by different traffic models. Their analytical model is validated by comparisons with simulations performed under different network scenarios.
