Departure Time

Currently mobile phones are not only used as a medium to communicate to phone and sms only, but also as a medium to communicate directly via the Internet or packet data service (GPRS) to send and receive data. DAMRI is a state-owned enterprises engaged in the transportation field. For existing activities in the company such as booking tickets, search the scheduled departure time, and the price of a bus ticket so prospective buyer can only do it queued through the outlet/counters and via telephone only. The development method used in this study is Mobile Application Development. The authors aimed to create a mobile application android-based ticket reservation (m-Reservation) application in order to facilitate the customer in activity booking tickets, viewing departure schedule, checking the list of reservations and seeing the info posted directly via android smartphone.

Packet Length

Energy level performances of three packet delivery schemes in Wireless Sensor Networks (WSN) are evaluated in presence of Rayleigh fading. Three different information delivery mechanisms are investigated using regenerative relays with or without error correction capability. Energy consumption for successful delivery of a data packet for each mechanism is evaluated and compared under several conditions of node density, bit rate, transmit power, and channel fading. Energy efficiencies of different retransmission schemes are also evaluated. Further, an optimal packet length based on energy efficiency is derived. Impact of optimal packet size on average number of retransmission and total energy expenditure is analyzed for each delivery scheme.
