As the devices in Wireless Sensor Networks (WSNs) are small in size, and have resource constraints such as memory utilization, power consumption, and processing speed that needs to be taken in consideration. The security and life span of sensor nodes is compromised with these restraints. The purpose of this paper is to assess the performance of the Secure Force algorithm on an 8-bit microcontroller...
This paper proposes and implements an embedded wireless access control system using a combination of RFID and MMS technologies. The RFID and MMS sections are each controlled by a cost effective AT89C52 microcontroller. The microcontroller in RFID section is responsible for reading the user tag information, searching the read information in a memory chip for a match and triggering the microcontroller...
This paper proposes and implements a solution for enhancing public transportation management services based on GPS and GSM in Punjab province of Pakistan. The system consists of four modules: BUS Station Module, In-BUS Module, BASE Station Module and BUS Stop Module. Equipped with PC and GSM modem, BUS Station Module sends the initialization information containing the bus number and license plate...
