Performance of slotted ALOHA in multiple joint cells of wireless networks

In wireless networks, multiple-cell structure to cover a wider area is a common approach. As the channels are usually hard to predict due to fast, deep, and dynamic fading, many traditional protocols like token passing, carrier sense multiple access, etc. are not appropriate to maintain successful performance. Slotted ALOHA and its variations are still attractive approaches. Traditional analysis on slotted-ALOHA is based on single-cell structure which is not the best model in future wireless personal communication networks. The authors study the performance of the slotted-ALOHA in joint cells of wireless networks. The impact of joint cells is well analyzed and numerical results are provided
