Wireless Mesh Networks (WMNs) have been widely deployed as a new communication paradigm that can provide innovative services for a community (neighborhood, campus, etc.). WMNs are capable to provide both delay-sensitive services such as Voice over Internet Protocol (VoIP) and delay-insensitive services such as peer-to-peer file sharing. Network routing protocols in WMNs often employ the minimum-hops...
In this paper, we examine the effect of retransmission cutoff in slotted ALOHA systems employing the binary exponential backoff (BEB) algorithm, in terms of throughput and delay performance, system stability and packet dropping probability. For comparison, the performance of the BEB algorithm without retransmission cutoff is presented. We consider a finite population of users competing for channel...
This paper examines throughput and delay performances of multipacket reception (MPR) slotted ALOHA systems with the exponential backoff (EB) algorithm which consists of an initial transmission probability, exponentially decaying factor and a maximum number of backoff stages. We assume a finite population model and the saturated traffic condition where every terminal always has a packet to transmit...
