Abstract: In CDMA wireless ad-hoc networks; an important goal is, permitting the requested calls of different users maintaining the quality of service. Because of interference and power, the CDMA capacity is restricted in general. The interference will increase as soon as the number of users rises by the reason of non-orthogonal factor. Consequently, there is a limit to the maximum number of users. In this paper, a cross-layer based joint scheduling and power control algorithm has been proposed with the objective of minimizing the interference level and call rejection rate. For achieving this, the algorithm determines the optimum set of admissible users with suitable transmitting power level. We introduce the notion of power control as part of a contention-based multiple access protocol that characterizes successful transmissions depending on a set of signal-to-interference-and-noise ratio (SINR) constraints (which directly translates to quality of service (QoS) constraints !
on the bit-error rate (BER) at individual receivers). The performance of our algorithm in a set of admissible and non-admissible users has been assessed using simulation results. Moreover, it is exposed that power control algorithm converges for a set of admissible users.
Keywords: Ad-hoc networks, CDMA, SINR (signal-to-interference-and-noise ratio), QoS (Quality of service), BER (bit-error rate), Cross layer design.
