Title :
Location balancing in ALOHA RAN by power control
Abstract :
Power control schemes for a packet radio access network based on S-ALOHA are investigated with the aim of achieving location balance. As a performance measure, packet delay, as a function of distance from the central base station, is derived analytically for a uniform distribution of users over a circular cell. The effect of shadow fading is accounted for and this is found to improve the performance of the system. A scheme that equalizes the average received power is proposed to achieve perfect location balance in terms of packet delay. Additionally, a scheme supporting a limited dynamic range and discrete levels of transmission power is proposed as a more realistic approach for implementation purposes.
