Modeling and performance evaluation for both infrastructured and infrastructureless wireless networks

During the last decade, advances in both hardware and software techniques have resulted in mobile communications and wireless networking common and miscellaneous. Next generation of wireless communications will include both prestigious infrastructured wireless networks and novel infrastructureless wireless networks. The future wireless mobile networks will generally be characterized by heterogeneity---a mixture of wireless cellular networks, wireless LANs (WLANs), mobile ad hoc networks (MANETs), wireless sensor networks (WSNs), etc.; The objective of this dissertation is to address the modeling and performance evaluation issues for both infrastructured and infrastructure less wireless networks. For this sake, we discuss the modeling and performance evaluation methods and develop a number of analytic models or schemes and analyze the system performance of associated wireless networks through many different performance measures.; We develop the dynamic partition with preemptive priority (DPPP) scheme and complete sharing with preemptive priority (CSPP) scheme for wireless cellular networks and analyze their performance by two-dimensional Markov process. We also develop analytic models and performance evaluation methods for hierarchical cellular networks (HCNs) with bidirectional overflow and take-back strategies, and for the integrated 3G (3rd generation wireless systems) and WLAN networks. In addition, we develop an analytic traffic flow model and a connection availability model for evaluating the performance of homogeneous mobile ad hoc networks (MANETs), and an analytic traffic model and three queue management schemes for a heterogeneous multi-hop MANET. Finally, we develop a QoS (quality of service) supporting scheme and an explicit solution on the energy distribution at different clusters through analytic modeling for a cluster based wireless sensor network.
