On Throughput Estimation of CDMA Unslotted ALOHA System for Random Access Networks

We employ the Simplified Improved Gaussian Approximation (SIGA) to estimate the performance of a connectionless-type CDMA packet communication system. In this system, a user s station can asynchronously and randomly transmit, making performance analysis hard due to the fluctuation of interfering users. We address this performance hardness by simulating a real world setting of the unslotted ALOHA network. Our simulation provides means of observing and reporting the system s specifications and performance under diverse boundaries.
