Suppose that a mobile station is moving along a straight line from base station BS1 to base station BS2 as shown in the figure below. The distance between the base stations is D = 2000 m. The received power (in dBm) at base station i, from the mobile station, is modeled as a function of distance as follows: P_i(d) = P - 10v*log10(d/D) (dBm), where d is the distance between the mobile and the base station i, in meters. P is the received power at distance d from the mobile antenna. Assume that the base stations' antenna heights are negligible compared to the distance between the mobile and the base stations. Further assume that P = 0 dBm and d = 1 m. Let v denote the path loss exponent, which is assumed to be equal to 2. Consider the four handoff algorithms: "RSS", "RSS + Threshold of -61 dBm", "RSS + Hysteresis of 2 dBm", and "RSS + Hysteresis of 2 dBm + Threshold of -61 dBm". For each of the algorithms, determine how far the mobile is from BS1 when it changes its association from BS1 to BS2. BS1 BS2 mobile D = 2000m d1 d2

As a mobile node gets farther from a base station, what are two possible (even if not always probable) actions that the base station could take to ensure that loss of frames does not increase? Describe the practical limitations of both approaches.
As a mobile unit in communication with a base station moves, what factors determine the need for power control and the amount of power adjustment?
