Transactions in m-commerce environm

Transactions in m-commerce environments are used to transmit messages and provide atomicity, consistency, isolation, and durability (ACID). Ensuring ACID or similar properties ishard to achieve in m-commerce due to the aforementioned limitations of the mobile terminals and frequent disconnections. A mobile transaction is atomic if either all the operationsspecified in the transaction are successfully executed or the executed operations are compensated (i.e., their effects deleted). Three types of atomicity can be defined for e-commerce:money atomicity, goods atomicity, and certified delivery (Tygar, 1996). They can be appliedto mobile environments. Money atomicity states that the m-commerce protocols must guarantee that funds are transferred from one party to another without the possibility of thecreation or destruction of money. Goods atomic protocols are money atomic and should beable to provide an exact transfer of goods for the money paid. Finally, a certified deliveryprotocol should be goods atomic and allow both the merchant and the customer to proveexactly which merchandise is received if the money is transferred. Ensuring atomicity in mcommerce is a complicated process. Mobile devices may be unreachable or may be unableto participate completely in the mobile transaction. In addition, atomicity needs to be jointlyhandled with security measures.
