Mobile and Wireless Communications.

Abstract : This report lists publications, patents, presentations and honors related to an ONR sponsored research grant on Mobile and Wireless Communications. The investigation develops new techniques, as well as performance evaluation models and tools for mobile and wireless communication systems. Configurations that support a mixture of mobile platform types and mixed types of telecommunications traffic are emphasized. Channel assignment and cellular layout strategies are investigated and an analytical framework based on multi-dimensional birth-death processes is developed to encompass a broad range of relevant issues. Specific topics include consideration of new channel borrowing schemes, mixed satellite and terrestrial systems, and methods that support platforms with differing mobilities and mixed teletraffic sources, such as data, voice and images. Important recent contributions include: (1) several important extensions of our analytical framework which allow platforms with highly variable mobility characteristics to be considered; (2) adaptive location management schemes for mobile communications; (3) performance models for mobile computing and communications; and, (4) cellular systems with multibeam antenna configurations.
