Abstract :
We propose the wireless integrated multiple access (WIMA) protocol under fixed contention non-interleaved-frame fixed-length (F-NIFFL) scheme, in which hybrid contention/reservation access is used for data. In this scheme, some of data packets are first transmitted in the contention-based slots, and the packets which collided or not transmitted in these slots are made reservation and are transmitted in the later reserved slots. A two-dimensional first-order Markov chain model is used for our analysis, and we show that our protocols can decrease the data-packet delay in the conventional WIMA under pure reservation NIFFL (PR-NIFFL). Especially in satellite networks, because of large round-trip propagation delay, our protocol is more effective
