Abstract :
The performance analysis of unslotted spread-spectrum packet radio network is very difficult because the received signal-to-noise ratio (SNR) fluctuates during the packet transmission. Past analyses are either based on complete enumeration or restricted to performance bounds. Here, a technique based on ballot theory is developed to analyze the performance of unslotted ALOHA spread-spectrum packet radio networks. This technique is also used to analyze the channel load sensing access protocol. An L-channel model is assumed
