An experimental evaluation of two distributed algorithms for validation of E-ticket protocols in a mobile computing environment

Keywords and Phrases

E-tickets; Tree-based protocol


"An E-ticket is a variant of traditional ticket system. The E-tickets are issued by an agency that can be used by different vendors to authorize and accept those issued E-tickets. These E-tickets can then be used for different purposes such as transportation, shopping, or an entrance ticket for a football game. One major issue associated with the E-tickets is the problem of validating the E-tickets also known as validation problem. The validation problem becomes more severe in a mobile environment. Mobility of a Mobile Host (MH) and failure of servers which are known as Mobile Support Stations (MSSs) are two major causes for the validation problem. Additional problems include the identification of multiple submissions of an E-ticket by a MH and forgery of E-tickets. This thesis addresses the experimental evaluation of the algorithms proposed for E-ticket validation protocols for mobile clients. The objective of the research was to observe the efficiency and throughput of the algorithms. These experiments consider different scenarios as well as different network topologies. Also presented is a comparative study of the performance results of different algorithms in different scenarios and topologies"--Abstract, leaf iii.
