Opis produktu
This book provides an original graph theoretical approach to the fundamental properties of wireless mobile adhoc networks. This approach is combined with a realistic radio model for physical links between nodes to produce new insight into network characteristics like connectivity degree distribution hopcount interference and capacity. The book establishes directives for designing adhoc networks and sensor networks. It will interest the academic community and engineers who roll out adhoc and sensor netAdhoc Networks Fundamental Properties and Network Topologiesprovides an original graph theoretical approach to the fundamental properties of wireless mobile adhoc networks. This approach is combined with a realistic radio model for physical links between nodes to produce new insights into network characteristics like connectivity degree distribution hopcount interference and capacity./This book clearly demonstrates how the Medium Access Control protocols impose a limit on the level of interference in adhoc networks. It hasbeen shown that interference is upper bounded and a new accurate method for the estimation of interference power statistics in adhoc and sensor networks is introduced here. Furthermore this volume shows how multihop traffic affects the capacity of the network. In multihop and adhoc networks there is a tradeoff between the network size and the maximum input bit rate possible per node. Large adhoc or sensor networks consisting of thousands of nodes can only support low bitrate applications. /This work provides valuable directives for designing adhoc networks and sensor networks. It will not only be of interest to the academic community but also to the engineers who roll out adhoc and sensor networks in practList of Figures. List of Tables. Preface. Acknowledgement. 1.
