Group randomly addressed polling with reservation for wireless integrated service networks

Group randomly addressed polling (GRAP) protocol has been demonstrated as an efficient and reliable multiple access protocol for wireless data networks. To serve time-bounded or integrated service traffic, a reservation technique is proposed in this paper to modify GRAP as reservation-group randomly addressed polling (R-GRAP) protocol. We first evaluate its performance for voice wireless networks to highlight the adequacy of adopting R-GRAP for future personal communications. Based on our evaluations to adopt R-GRAP to serve integrated voice and data traffic, we demonstrate the superiority of R-GRAP for wireless integrated service networks.
