The Research On The Cooperation Technology Of The Wireless Heterogeneous Network

With the development of wireless communication technology, oriented from the various requirements from the networks'coverage, the scale of the customers'commodity and the Quality of service (QoS), various wireless networks -such as the different kind of cellular networks, Wireless Local Area Network (WLAN), Wireless Personal Area Network (WPAN) and satellite communication networks are developed and applied. And more novel and different wireless networks are emerging. Perceive from the current state of wireless network, not any one of the aforementioned networks has the capability that it could satisfy the requirements from all users to all kind of services with high QoS, low prices with seamless access in global area. So it is commonly agreed that the future wireless network will be an integration of all kinds of wireless network with different technologies and different service. The heterogeneous developing trend in all aspects of the network topology, the bottom physics layer technology, the network protocols architecture, the service provision, and the strategies of network control and management put forward challenges and theoretical and technological problems for further research. And the appeal to all these networks should interconnected corporately made the problem stringent.Based on the perception to the trend of heterogeneity and cooperation for the future wireless network, the cooperation of the wireless heterogeneous network is taken as the research area of this dissertation. The main works include:1) Start from the analysis to the traffic model of the Low Earth Orbit(LEO) satellite systems, aim to the problem that the traffic burst in some time duration and in some"hot spot"area may affect the performance of LEO system, a new LEO-Ad hoc dual-mode networking model(LEO-Ad hoc dual-mode networking model- LADMNM)is proposed. Under the model, a novel geographic location based route (GLBR) algorithm for Ad Hoc networking is proposed. Theoretical analysis and simulation results have shown that the networking model and the route algorithm have distributed the traffic burst peak in the cell and have decreased the realistic call blocking probability and increased the valid channel utility rate of the system.2) Oriented from the analysis to the sense information distribution and practical engineering requirements to the wireless sensor network, a different Wireless Sensor Network Heterogeneous DePloyment Model (WSNHEDPM) is proposed, which is differ from the normal homogeneous deployment plan with huge quantitative trivial, resource-limited, random distributed in interesting area. The theoretical and experimental analysis is made to compare the both deployment plan in the parameters of the deployment cost, the power consumed and the survival time. The analytical and simulation results show that the heterogeneous deployment is more generic and more reasonable for the wireless sensor network to face the universal application area.3) Research work has been done on the Radio Resources Management and the utility optimization of the wireless heterogeneous network. A new Flexible Bandwidth Reservation Scheme (FBRS) for handover management and call admission control to the heterogeneous services in Low Earth Orbit (LEO) satellite systems is proposed. According to the analysis into the utility of all participants in future wireless networks and the analysis of the influence of the utility of all participants to the long-tern revenue of the service-provider, an Utility Oriented Radio Resource Management Algorithms (UORRMA) is proposed. The algorithms is composed of the pricing strategy, the call access control (CAC) strategy and the radio resource allocation (RRA) strategy and make decision based on the long-term utility of both the network and the customer to achieve an optimize equilibrium for the utility of the service-provider and the customer of the network.The dissertation is supported by the Armament Research Foundation 51421010805JW05 and the Jiangxi Science and Technology Project"the intellectual remote Bluetooth2.0 controller for energy saving".
